Abstract
Duck hepatitis A virus genotype 3 (DHAV-3) is the major cause of viral hepatitis in ducks in Asia. Previous studies have shown that ducklings younger than 21 days are more susceptible to DHAV-3. To elucidate the mechanism by which age affects the differential susceptibility of Pekin ducks to DHAV-3, intestinal (n = 520), liver (n = 40) and blood (n = 260) samples were collected from control and DHAV-3-infected ducks at 7, 10, 14, and 21 days of age. Comparisons of plasma markers, mortality rates, and intestinal histopathological data showed that the resistance of Pekin ducks to DHAV-3 varied with age. 16 S sequencing revealed that the ileal microbial composition was influenced by age, and this correlation was greater than that recorded for caecal microbes. Candidatus Arthromitus, Bacteroides, Corynebacterium, Enterococcus, Romboutsia, and Streptococcus were the differntially abundant microbes in the ileum at the genus level after DHAV-3 infection and were significantly correlated with 7 differentially expressed genes (DEGs) in 7- and 21-day-old ducklings. 3 immunity-related pathways were significantly different between 7- and 21-day-old ducklings, especially for IFIH1-mediated induction of the interferon-alpha/beta pathway, which induces differential production of CD8(+) T cells and was influenced by a combination of differentially abundant microbiota and DEGs. We found that microbes in the ileum changed regularly with age. The intestinal microbiota was associated with the expression of genes in the liver through IFIH1-mediated induction of the interferon-alpha/beta pathway, which may partially explain why younger ducklings were more susceptible to DHAV-3 infection.

Abstract
As the most prevalent pathogen of duck viral hepatitis (DVH), duck hepatitis A virus genotype 3 (DHAV-3) has caused huge economic losses to the duck industry in China. Herein, we obtained whole-transcriptome sequencing data of susceptible (S) and resistant (R) Pekin duckling samples at 0 h, 12 h, and 24 h after DHAV-3 infection. We found that DHAV-3 infection induces 5,396 differentially expressed genes (DEGs), 85 differentially expressed miRNAs (DEMs), and 727 differentially expressed lncRNAs (DELs) at 24 hpi in S vs. R ducks, those upregulated genes were enriched in inflammation and cell communications pathways and downregulated genes were related to metabolic processes. Upregulated genes showed high connectivity with the miR-33, miR-193, and miR-11591, and downregulated genes were mainly regulated by miR-2954, miR-125, and miR-146b. With the construction of lncRNA-miRNA-mRNA axis, we further identified a few aberrantly expressed lncRNAs (e.g., MSTRG.36194.1, MSTRG.50601.1, MSTRG.34328.7, and MSTRG.29445.1) that regulate expression of hub genes (e.g., THBD, CLIC2, IL8, ACOX2, GPHN, SMLR1, and HAO1) by sponging those highly connected miRNAs. Altogether, our findings defined a dual role of ncRNAs in immune and metabolic regulation during DHAV-3 infection, suggesting potential new targets for treating DHAV-3 infected ducks.

Abstract
The aim of the experiment was to evaluate the status of innate immunity, oxidative status and lipid accumulation in ducklings exhibiting varying susceptibilities to DHAV-3 infection. In the experiment, ducklings with different DHAV-3 susceptibilities were used. Samples were collected at 6, 12, 15, and 24 h post infection (hpi), with 5 samples per time point. Plasma biochemistry, antioxidant enzyme activities, lipid content of liver and kidney were detected in the experiment. Elevated plasma level of total bilirubin, direct bilirubin, and creatinine indicated the injury of liver and kidney in susceptible ducklings (P < 0.05). The histopathological sections showed the injury in kidney. During the infection time, there was an increase in the concentrations of reactive oxygen species and oxidative damage markers (malondialdehyde and nitric oxide) in plasma of susceptible ducklings, particularly at 24 hpi (P < 0.05). Compared with the resistant ducklings, DHAV-3 infection resulted in a significant increase in the plasma total triglyceride (TG) level and a decrease in glucose level in susceptible ducklings. Gene expression of the innate immune response was both investigated in liver and kidney. In resistant ducklings, the expressions levels of pattern recognition receptors RIG-I, MDA5 remained constant. In contrast, the gene expressions peaked at 24 hpi in the susceptible ducklings. DHAV-3 infection promoted the expression of IFN, IL6, IL12β, caspase-8 or caspase-9 in both liver and kidney of susceptible ducklings. In conclusion, DHAV-3 infection led to the mobilization of antioxidant defenses, alterations in lipid metabolism, and oxidative stress in susceptible ducklings during DHAV-3 infection.

Abstract
Duck hepatitis A virus type 1 (DHAV-1) can cause severe liver damage in infected ducklings and is a fatal and contagious pathogen that endangers the Chinese duck industry. The objective of this study was to explore the correlation mechanism of liver metabolism-gut microbiota in DHAV-1 infection. Briefly, liquid chromatography-mass spectrometry and 16S rDNA sequencing combined with multivariate statistical analysis were used to evaluate the effects of DHAV-1 infection on liver metabolism, gut microbiota regulation, and other potential mechanisms in ducklings. In DHAV-1-infected ducklings at 72 h postinfection, changes were found in metabolites associated with key metabolic pathways such as lipid metabolism, sugar metabolism, and nucleotide metabolism, which participated in signaling networks and ultimately affecting the function of the liver. The abundance and composition of gut microbiota were also changed, and gut microbiota is significantly involved in lipid metabolism in the liver. The evident correlation between gut microbiota and liver metabolites indicates that DHAV-host gut microbiome interactions play important roles in the development of duck viral hepatitis (DVH).

Abstract
To investigate the distribution and genetic variation in four vertically transmitted duck pathogens, including duck hepatitis B virus (DHBV), duck circovirus (DuCV), duck hepatitis A virus 3 (DHAV-3), and avian reoviruses (ARV), we conducted an epidemiology study using PCR and RT-PCR assays on a duck population. We found that DHBV was the most prevalent virus (69.74%), followed by DuCV (39.48%), and then ARV (19.92%) and DHAV-3 (8.49%). Among the 271 duck samples, two, three or four viruses were detected in the same samples, indicating that the coinfection of vertical transmission agents is common in ducks. The genetic analysis results showed that all four identified DuCV strains belonged to genotype 1, the DHAV-3 strain was closely clustered with previously identified strains from China, and the ARV stain was clustered under genotype 1. These indicate that different viral strains are circulating among the ducks. Our findings will improve the knowledge of the evolution of DuCV, DHAV-3, and ARV, and help choose suitable strains for vaccination.

Abstract
Adenovirus serves as an excellent viral vector and is employed in vector vaccine research. Duck hepatitis A virus type 1 (DHAV1) and duck adenovirus type 3 (DAdV3) cause significant economic losses in the Chinese duck industry. In this study, we found an excellent exogenous gene insertion site in DAdV3 genome of CH-GD-12-2014 strain, within 3 intergenic regions (IGR). Subsequently, we generated a recombinant duck adenovirus named rDAdV3-VP1-188, which exhibits excellent replication characteristics and immunogenicity of DAdV3 and DHAV1. Animal experiments showed that rDAdV3-VP1-188 can provide 100% protection against the DAdV3 and 80% protection against DHAV1. These results showed that rDAdV3-VP1-188 could induce protection against DAdV3 and DHAV1 in ducks, thus indicating the feasibility of DAdV3 as a vector for the development of avian vector vaccines. These insights contribute to the further development of DAdV3 vectors and other adenovirus vectors.

Abstract
Duck hepatitis A virus (DHAV) is one of key pathogens for duck viral hepatitis, especially in Asian duck industry. Currently, two main genotypes (DHAV-1 and -3) exist. To explore insightfully the evolutionary character, we assessed the available 141 full-length genome sequences of DHAV isolated in 1986-2020 globally and divided DHAV-1 and DHAV-3 into further seven (DHAV-1 a-g) and five (DHAV-3 a-e) sub-clades, respectively. Phylogenetic and phylogeographic network analyses indicated great genetic diversity of DHAV identified in China, where the DHAV-1 cluster and DHAV-3 cluster were linked by virus strain HDHV1-BJ (GenBank ID: FJ157172.1) and Du_CH_LSD_090612 (GenBank ID: JF828995.1) via a long mutational branch and intermediate strains. Several strains previously identified as DHAV-1 according to the partial gene sequences were actually clustered within DHAV-3 in full-length genome-based analysis. Furthermore, we identified 32 recombination events across virus genome with the recombination hotspot at the 5' end and upstream of the capsid coding region. The highest variability of DHAV polyprotein was shown at the upstream region of the N terminus P-loop region, e.g., amino acids 672-716, followed by the aa 334-359 in the Capsid encoding region. The results presented here provides a robust insight into the genetic exchange patterns of DHAV genomes during the past decades, which may be used to map the evolutionary history and facilitate preventive measures of DHAVs.

Abstract
BACKGROUND Duck hepatitis A virus (DHAV) is a single-stranded, positive-strand small RNA virus that causes a very high mortality rate in ducklings. The DHAV-3 subtype incidence rate has recently increased in China, causing great economic losses to the waterfowl breeding industry. We analyzed the protection rate of DHAV vaccines used in mainland China from 2009 to 2021 and evaluated the effectiveness of vaccine prevention and control to reduce the economic losses caused by DHAV to the waterfowl breeding industry. We screened five electronic research databases and obtained 14 studies and patents on the protection efficiency of DHAV-1 and DHAV-3 vaccines. RESULTS Meta-analysis demonstrated that immunized ducklings produced higher antibody levels and had a significantly higher survival rate than non-immunized ducklings [relative risk (RR) = 12, 95% confidence interval (CI) 6-26, P < 0.01]. The age of the ducks and vaccine valence did not affect protection efficiency. Data source analysis of the vaccine protection rate demonstrated that the vaccines conferred immune protection for ducklings in both small-scale experiments and large-scale clinical conditions. The analysis results revealed that although the vaccines conferred protection, the immune protective effect differed between small-scale experimental conditions and large-scale clinical conditions. This might have been due to non-standard vaccination and environmental factors. CONCLUSIONS Domestic DHAV vaccines can protect ducklings effectively. The subjects immunized (breeding ducks or ducklings) and vaccine valence had no effect on the protective effect. Both small-scale experiments and large-scale clinical conditions conferred immune protection on ducklings, but vaccine immunization under small-scale experimental conditions had slightly better protective effects than large-scale clinical immunization.

Abstract
Duck viral hepatitis (DVH), mainly caused by duck hepatitis A virus (DHAV), is a highly fatal and rapidly spreading infectious disease of young ducklings that seriously jeopardizes the duck industry worldwide. DHAV type 1 (DHAV-1) is the main genotype responsible for disease outbreaks since 1945, and the disease situation is complicated by the emergence and dissemination of a novel genotype (DHAV-3) in some countries in Asia and Africa. Live attenuated DHAV vaccines are widely used to induce a considerable degree of protection in ducklings. Breeder ducks are immunized with inactivated or/and live DHAV vaccines to achieve satisfactory levels of passive immunity in progeny. In addition, novel characteristics of virus transmission, pathogenicity and pathogenesis of DHAV were recently characterized, necessitating the development of new vaccines and effective vaccination programmes against DVH. Therefore, a systematic dissection of the profiles, strengths and shortcomings of the available DHAV vaccines is essential. Moreover, to further increase the efficiency of vaccine production and administration, the development of next-generation DHAV vaccines using cutting-edge technologies is also required. In this review, based on a comprehensive summary of the research advances in the epidemiology, pathogenicity, and genomic features of DHAV, we focus on reviewing and analysing the features of the commercial and experimental DHAV vaccines. We also propose perspectives for disease control based on the specific disease situations in different countries. This review provides essential information for vaccine development and disease control of DVH.

Abstract
DNAzymes effectively inhibit the expression of viral genes. Duck hepatitis A virus type-1 (DHAV-1) genomic RNA carries an internal ribosome entry site (IRES). The IRES initiates the translation of DHAV-1 via a mechanism that differs from that of cap-dependent translation. Therefore, it is an attractive target for the treatment of DHAV-1. In this study, we designed 6 DNAzymes (Dzs) specifically targeting 300-618 nt sequence in the DHAV-1 5'untranslated region (UTR; a predicted IRES-like element). In the presence of divalent metal ions, three designed DNAzymes (DZ369, DZ454, and DZ514) efficiently cleaved the 300-618 nt sequence of the DHAV-1 5'UTR RNA. The activity of the Dzs was particularly dependent on Mg2+ ions. Subsequently, the translation inhibitory activity of these Dzs was determined by western blotting experiments. The Dzs effectively inhibited the translation mediated by the 300-618 nt of DHAV-1 5'UTR in duck embryo fibroblasts (DEFs). Importantly, DZ454 showed the strongest inhibitory effect, and its inhibition was time and dose dependent. However, none of the Dzs showed significant inhibition of cap-dependent translation. These results suggest that these Dzs show specificity for target RNA. Moreover, DZ454 inhibited the replication of DHAV-1. In conclusion, the designed DNAzymes can be used as inhibitors of DHAV-1 RNA translation and replication, providing new insights useful for the development of anti-DHAV-1 drugs.

Abstract
BACKGROUND Duck viral hepatitis (DVH) has a significant economic impact on duck industry, and duck hepatitis A virus genotype 3 (DHAV-3) is the most prevalent pathogen of DVH in Asian duck industry. The detailed study connecting differentially expressed genes (DEGs) and the differential resistance to DHAV-3 have not been accurately described, although a large numbers of DEGs have been identified by transcriptomic studies. RESULTS Here, a resistant Pekin duck line (Z8R) and a susceptible Pekin duck line (Z8S) as models, high mortality and dramatically increased aspartate aminotransferase (AST), alanine aminotransferase (ALT) and the expression of immune-related genes of Z8S group were shown to be noticeable signs of cases caused by DHAV-3 infection. Compared with the control (Con) group, 1117 down-regulated DEGs and 612 up-regulated DEGs were found in the Z8S group and 37 down-regulated DEGs and 82 up-regulated DEGs were found in the Z8R group. Ultimately, the expression patterns of 10 DEGs were found to be diametrically opposite in Z8R and Z8S group. Functional analysis revealed that IFITM1 was associated with cell growth suppression, which was considered a key candidate gene. Results of flow cytometry showed that the conserved regions of IFITM1 (213-317 bp) could affected the cell cycle of duck embryo fibroblast (DEF) cells after infection with DHAV-3. Transcriptome and western blot analysis suggested that the CCND1, CCNE1 and CDK6 were significantly up-regulated in susceptible ducks by comparing with Con group. CONCLUSIONS The hepatic injury and pathogenic outcomes caused by DHAV-3 infection were more severe in Z8S group compared to Z8R. Results of transcriptomics analysis and flow cytometry suggested that DHAV-3 infection can induce cell cycle changes that may be associated with IFITM1 expression level. These data will greatly enhance our understanding of the pathogenesis of DHAV-3 infection in ducklings and have implications for development of resistance breeding.

Abstract
Duck hepatitis A virus type 1 (DHAV-1) is one of the main pathogens responsible for death in ducklings. Autophagy is a catabolic process that maintains cellular homeostasis, and the PI3KC3 protein plays an important role in the initiation of autophagy. DHAV-1 infection induces autophagy in duck embryo fibroblasts (DEFs) but the molecular mechanism between it and autophagy has not been reported. First, we determined that DHAV-1 infection induces autophagy in DEFs and that autophagy induction is dependent on the integrity of viral proteins by infecting DEFs with UV-inactivated or heat-inactivated DHAV-1. Then, in experiments using the pharmacological autophagy inducer rapamycin and the autophagy inhibitor chloroquine, autophagy inhibition was shown to reduce intracellular and extracellular DHAV-1 genome copies and viral titres. These results suggest that autophagy activated by DHAV-1 infection in DEFs affects DHAV-1 proliferation and extracellular release. Next, we screened the autophagy-inducing effects of the DHAV-1 structural proteins VP0, VP3, and VP1 and found that all DHAV-1 structural proteins could induce autophagy in DEFs but not the full autophagic flux. Finally, we found that VP1 promotes protein expression of PI3KC3 and Beclin1 by western blot experiments and that VP1 interacts with PI3KC3 by co-immunoprecipitation experiments; moreover, 3-MA-induced knockdown of PI3KC3 inhibited VP1 protein-induced autophagy in DEFs. In conclusion, the DHAV-1 structural protein VP1 regulates the PI3KC3 complex by interacting with PI3KC3 to induce autophagy in DEFs.

Abstract
The nomenclature of duck viral hepatitis (DVH) was historically not a problem. However, 14 hepatotropic viruses among 10 different genera are associated with the same disease name, DVH. Therefore, the disease name increasingly lacks clarity and may no longer fit the scientific description of the disease. Because one disease should not be attributed to 10 genera of viruses, this almost certainly causes misunderstanding regarding the disease-virus relationship. Herein, we revisited the problem and proposed an update to DVH disease classification. This classification is based on the nomenclature of human viral hepatitis and the key principle of Koch's postulates (“one microbe and one disease”). In total, 10 types of disease names have been proposed. These names were literately matched with hepatitis-related viruses. We envision that this intuitive nomenclature system will facilitate scientific communication and consistent interpretation in this field, especially in the Asian veterinary community, where these diseases are most commonly reported.

Abstract
Duck hepatitis A virus type 1 (DHAV-1) is a highly lethal virus that severely affects the duck industry worldwide. Long noncoding RNAs (lncRNAs) exert crucial roles in pathogen attacks. Here, we conducted deep transcriptome analysis to investigate the dynamic changes of host lncRNAs profiles in DHAV-1-infected duck embryo fibroblasts. We identified 16,589 lncRNAs in total and characterized their genomic features. Moreover, 772 and 616 differentially expressed lncRNAs (DELs) were screened at 12 and 24 h post-infection. Additionally, we predicted the DELs’ cis- and trans-target genes and constructed lncRNA-target genes regulatory networks. Functional annotation analyses indicated that the putative target genes of DELs participated in diverse vital biological processed, including immune responses, cellular metabolism, and autophagy. For example, we confirmed the dysregulation of pattern recognition receptors (TLR3, RIG-I, MDA5, LGP2, cGAS), signal transducers (STAT1), transcription factors (IRF7), immune response mediators (IL6, IL10, TRIM25, TRIM35, TRIM60, IFITM1, IFITM3, IFITM5), and autophagy-related genes (ULK1, ULK2, EIF4EBP2) using RT-qPCR. Finally, we confirmed that one DHAV-1 induced lncRNA-XR_003496198 is likely to inhibit DHAV-1 replication in DEFs. Our study comprehensively analyzed the lncRNA profiles upon DHAV-1 infection and screened the target genes involved in the innate immune response and autophagy signaling pathway, thereby revealing the essential roles of duck lncRNAs and broadening our understanding of host-virus interactions.

Abstract
In this study, to improve the quality of a live attenuated vaccine for duck viral hepatitis (DHV), the lyophilization of a heat-resistant duck hepatitis virus vaccine was optimized. The optimized heat protectors were made of 10% sucrose, 1.2% pullulan, 0.5% PVP, and 1% arginine, etc., with a titer freeze-drying loss of ≤0.50 Lg. The vaccine product’s valence measurements demonstrated the following: the vaccine could be stored at 2–8 °C for 18 months with a virus titer loss ≤0.91 Lg; at 37 °C for 10 days with a virus valence loss ≤0.89 Lg; and at 45 °C for 3 days with a virus titer loss ≤0.90 Lg. Regarding safety, no deaths occurred in two-day-old ducklings immunized with a 10 times dose vaccine; their energy, diet, and weight gain were all normal, demonstrating that the DHV heat-resistant vaccines were safe for ducklings and did not cause any immune side effects. Duck viral hepatitis freeze-dried vaccine began to produce antibodies at 7 d after immunization, reached above 5.0 on 14 d, and reached above 7.0 on 21 d, showing a continuous upward trend. This indicates that duck viral hepatitis vaccine has a good immunogen level. The optimization of the freeze-drying process saves costs and also improves the quality of the freeze-drying products, which provides important theoretical and technical support for the further study of vaccine products.

Abstract
Duck hepatitis A virus 1 (DHAV-1) is a highly contagious etiological agent that causes acute hepatitis in young ducklings. MicroRNAs (miRNAs) play important regulatory roles in response to pathogens. However, the interplay between DHAV-1 infection and miRNAs remains ambiguous. We characterized and compared miRNA and mRNA expression profiles in duck embryo fibroblasts cells (DEFs) infected with DHAV-1. In total, 36 and 96 differentially expressed (DE) miRNAs, and 4110 and 2595 DE mRNAs, were identified at 12 and 24 h after infection. In particular, 126 and 275 miRNA-mRNA pairs with a negative correlation were chosen to construct an interaction network. Subsequently, we identified the functional annotation of DE mRNAs and target genes of DE miRNAs enriched in diverse Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, which may be important for virus resistance, cell proliferation, and metabolism. Moreover, upregulated miR-222a could negatively regulate DHAV-1 replication in DEFs and downregulate integrin subunit beta 3 (ITGB3) expression by targeting the 3' untranslated region (3'UTR), indicating that miR-222a may modulate DHAV-1 replication via interaction with ITGB3. In conclusion, the results reveal changes of mRNAs and miRNAs during DHAV-1 infection and suggest miR-222a as an antiviral factor against DHAV-1.

Abstract
Since the first report from Cherry Valley ducks on a commercial duck farm in China (2008), duck astrovirus type 1(DAstV-1) -associated duck viral hepatitis (DVH) have been detected in several commercial duck flocks. A highly acute disease characterized by hepatitis broke out in ducklings in Shandong Province in March 2021, all diseased ducks have been immunized against duck viral hepatitis vaccine. One DAstV-1 strain, designated as DAstV-SDWF, was isolated from a diseased duckling. Here, the isolation, cultivation and characterization of DAstV-1 isolate are described. The isolated astrovirus grew well in the LMH cell line. To determine the entire genomic of the DAstV-SDWF isolate, next-generation sequencing (NGS) technique was conducted on Illumina HiSeq platform. Complete genome sequence analysis revealed that DAstV-SDWF isolate was 91.6%-98.6% homology with others DAstV-1 deposited in Genbank. Similar clinical symptoms were successful reproduced by experimental infection study using the DAstV-SDWF isolate. DAstV-SDWF is the first DAstV-1 strain whose experimental infection study has been conducted in China. Results of above data demonstrated the DAstV-1 could be one of the causative agents of the DVH occurring in China. The present works are likely to provide new insights into the pathogenicity and evolution of DAstV-1 in ducks. This article is protected by copyright. All rights reserved.

Abstract
Duck enteritis virus (DEV) and duck hepatitis A virus (DHAV) are prevalent duck pathogens, causing significant economic losses in the duck industry annually. Using a fosmid-based rescue system, we generated two DEV recombinants, rDEV-UL26/27-P13C and rDEV-US7/8-P13C, in which the P1 and 3C genes from DHAV type 3 (DHAV-3) were inserted into the DEV genome between genes UL26 and UL27 or genes US7 and US8. We inserted a self-cleaving 2A-element between P1 and 3C, allowing the production of both proteins from a single open reading frame. P1 and 3C were simultaneously expressed in infected chicken embryo fibroblasts, with no difference in growth kinetics between cells infected with the recombinant viruses and those infected with the parent DEV. Both recombinant viruses induced neutralizing antibodies against DHAV-3 and DEV in ducks. A single dose of the recombinant viruses induced solid protection against lethal DEV challenge and completely prevented DHAV-3 infection as early as 7 days post-vaccination. These recombinant P1- and 3C-expressing DEVs provide potential bivalent vaccines against DEV and DHAV-3 infection in ducks.

Abstract
The duck hepatitis A virus 1 (DHAV-1) 2C protein was predicted to be a superfamily III helicase member and includes nucleotide binding (NTB) and putative RNA helicase activity motifs. To study whether DHAV-1 2C protein has NTB activity, we expressed DHAV-1 2C protein with maltose binding protein (MBP) to solve its poor solubility in a prokaryotic expression system. We showed that the DHAV-1 2C protein has nucleoside triphosphatase (NTPase) activity by measuring the released phosphate. The NTPase of the DHAV-1 2C protein is Mg2+ indispensable and affected by other biochemical characteristics such as Mn2+, Ca2+, Zn2+, Na+ and pH. Guanidine hydrochloride (GdnHCl), a potent inhibitor of viral RNA replication, inhibited ATPase activity of the DHAV-1 2C protein in a dose-dependent manner. Finally, we constructed three mutants to identify the key site for the ATPase activity of the DHAV-1 2C protein. These results indicate that lysine at position 151 of the DHAV-1 2C protein is very important for NTPase activity. Here, we demonstrated and partially characterized that the DHAV-1 2C protein has NTPase activity and showed that mutation of the lysine in the conserved Walker A impairs that activity. The results serve to confirm what is readily predicted from previous work on picornavirus 2C proteins. It also provides a basis for further study of the 2C protein and the function of NTPase activity on the viral life cycle.

Abstract
Duck hepatitis A virus (DHAV), which mainly infects 1- to 4-week-old ducklings, has a fatality rate of 95% and poses a huge economic threat to the duck industry. However, the mechanism by which DHAV-1 regulates the immune response of host cells is rarely reported. This study examined whether DHAV-1 contains a viral protein that can regulate the innate immunity of host cells and its specific regulatory mechanism, further exploring the mechanism by which DHAV-1 resists the host immune response. In the study, the dual-luciferase reporter gene system was used to screen the viral protein that regulates the host innate immunity and the target of this viral protein. The results indicate that the DHAV-1 3C protein inhibits the pathway upstream of interferon (IFN)-β by targeting the interferon regulatory factor 7 (IRF7) protein. In addition, we found that the 3C protein inhibits the nuclear translocation of the IRF7 protein. Further experiments showed that the 3C protein interacts with the IRF7 protein through its N-terminus and that the 3C protein degrades the IRF7 protein in a caspase 3-dependent manner, thereby inhibiting the IFN-β-mediated antiviral response to promote the replication of DHAV-1. The results of this study are expected to serve as a reference for elucidating the mechanisms of DHAV-1 infection and pathogenicity.

Abstract
Duck hepatitis A virus (DHAV), an avian picornavirus, causes high-mortality acute disease in ducklings. Among the three serotypes, DHAV-1 is globally distributed, whereas DHAV-2 and DHAV-3 serotypes are chiefly restricted to Southeast Asia. In this study, we analyzed the genomic evolution of DHAV-1 strains using extant GenBank records and genomic sequences of 10 DHAV-1 strains originating from a large disease outbreak in 2004-2005, in Hungary. Recombination analysis revealed intragenotype recombination within DHAV-1 as well as intergenotype recombination events involving DHAV-1 and DHAV-3 strains. The intergenotype recombination occurred in the VP0 region. Diversifying selection seems to act at sites of certain genomic regions. Calculations estimated slightly lower rates of evolution of DHAV-1 (mean rates for individual protein coding regions, 5.6286 × 10-4 to 1.1147 × 10-3 substitutions per site per year) compared to other picornaviruses. The observed evolutionary mechanisms indicate that whole-genome-based analysis of DHAV strains is needed to better understand the emergence of novel strains and their geographical dispersal.

Abstract
Duck hepatitis A viruses (DHAV-1, DHAV-2, and DHAV-3) are the predominant causes of duck virus hepatitis (DVH), a disease of ducklings that leads to massive morbidities, mortalities, and economic losses. As a duck-producing country, Egypt suffered lately from several attacks of DVH, despite the regular vaccination of birds. Between Spring 2016 and Summer 2018, 54 duckling flocks in the Sharkia province of Egypt were tested using the reverse-transcription PCR (RT-PCR) based on the DHAV-3D targeting primers. Of them, 27.8% (15/54) were positive. Upon retesting of positive samples using RT-PCR and duck hepatitis A virus (DHAV)-3 VP1-based primers, 33.3% (5/15) contained DHAV-3 RNA. For further analysis at the molecular level, the VP1 and the 3D genes were sequenced using the same primer sets used earlier. The phylogenetic trees confirmed that study sequences belonged to DHAV-3. However, they were displayed as a separate cluster following a geographically dependent distribution. They were also completely unrelated to the Egyptian DHAV-1-based vaccine. This was further confirmed by low nucleotide and amino acid identities in relation to this vaccine. In addition, the VP1 and 3D genes had the same phylogenetic topography. The study VP1 sequences had three unique amino acid substitutions (L59, V208 only in one strain, and C219). As far as we know, this is the first report on DHAV-3 outside Asia, particularly in Egypt. Accordingly, the vaccination strategy against DHAV should be quickly updated to avoid further dissemination of the virus. The epidemiology, pathogenicity, and evolution of DHAV-3 should be carefully monitored in Egypt.

Abstract
Duck hepatitis A virus 1 (DHAV-1) can cause high morbidity and fatal acute infectious hepatitis in ducklings, which seriously endangers animal husbandry. Viroporin is a small molecular weight hydrophobic transmembrane protein encoded by the virus, that has been suggested to induce autophagy in host cells by increasing the membrane permeability through disturbing the ion balance. In this study, we aimed to investigate whether the DHAV-1 2B protein can induce autophagy in DEF cells with a viroporin-like function. Bioinformatics analysis has indicated that the 2B protein is characterized by a viroporin domain, which is consistent with the type IA viroporin transmembrane protein. We experimentally confirmed that the 2B protein disturbed the Ca2+ balance of infected cells by elevating the intracellular Ca2+ concentration. Eukaryotic expression of the 2B protein upregulates the expression of microtubule-associated protein 1 light chain 3 II (LC3-II) and the number of autophagosomes in the cell. Interestingly, the Western Blot (WB) results showed that 2B protein expression induced less protein degradation of the autophagic substrate sequestosome 1 (SQSTM1/p62) than the positive control, while microscopy observations showed that the autophagosomes did not colocalize with the lysosomes. In summary, 2B protein expression induced autophagy in host cells, but the autophagic flow was incomplete. The results of this experiment are expected to provide reference scientific data for elucidating the infective and pathogenic mechanism of DHAV-1.

Abstract
Duck hepatitis A virus type 1 (DHAV-1) is the main pathogen of duck viral hepatitis, but the efficacy of the licensed commercial vaccine needs to be further improved. Therapeutic measures of specific drugs for DHAV-1-infected ducklings need to be urgently developed. Baicalin possesses good antiviral effects. This study aims to investigate the mechanism of baicalin in protecting hepatic mitochondrial function from DHAV-1. The ELISA method was used to detect changes of hepatic and mitochondrial catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPX), inducible nitric oxide synthase (iNOS), adenosine triphosphate (ATP), and malondialdehyde (MDA) levels in vivo and vitro. Hematoxylin and eosin sections and transmission electron microscopy were used to observe liver pathological changes and mitochondrial structural changes. The changes in mitochondrial membrane potential were detected by JC-1 staining method. Western blot and quantitative real-time PCR were employed to analyze the gene and protein expressions in the nuclear erythroid 2-related factor 2 (Nrf2)/antioxidant responsive element (ARE) pathway in duck embryonic hepatocytes infected with DHAV-1. Results showed the administration of baicalin increased the survival rate of ducklings, and alleviated hepatic damage caused by DHAV-1 by enhancing the antioxidant enzyme activities of the liver and mitochondria, including SOD, GPX, CAT, and reducing lipid peroxidative damage (MDA content) and iNOS activities. The mitochondrial ultrastructure changed and the significant increase of ATP content showed that baicalin maintained the structural integrity and ameliorated mitochondrial dysfunction after DHAV-1 infection. In vitro, DHAV-1 infection led to loss of mitochondrial membrane potential and lipid peroxidation and decreased antioxidative enzyme activities (SOD, GPX) and mitochondrial respiratory chain complex activities (succinate dehydrogenase, cytochrome c oxidase). Baicalin relieved the above changes caused by DHAV-1 and activated the gene and protein expressions of Nrf2, which activated ARE-dependent genes including heme oxygenase-1 (HO-1), nicotinamide adenine dinucleotide phosphate quinone oxidoreductase 1 (NQO1), SOD-1, and GPX-1. In addition, baicalin increased the protein expressions of antioxidative enzymes (SOD, GPX). Hence, baicalin protects the liver against oxidative stress in hepatic mitochondria caused by DHAV-1 via activating the Nrf2/ARE signaling pathway.

Abstract
Duck viral hepatitis (DVH) mainly affects ducklings under 1 month of age, causes liver necrosis, enlargement, and hemorrhage, and is highly lethal, seriously jeopardizing the duck industry. The prevalence of serotypes DHAV-1 and DAstV-3 is increasing, and co-infection is common. Moreover, the similar clinical characteristics of the DHAV-1 and DAstV-3 infections and high frequency of co-infection make diagnosis difficult. In this study, to establish a method for the rapid simultaneous detection of DHAV-1 and DAstV-3 , two pairs of specific primers were designed according to their conserved gene regions. A SYBR Green I-based real-time PCR assay was successfully established that can quickly and differentially detect the two viruses. Moreover, the assay is highly specific and does not show cross-reaction with other common viruses. The detection limit of the method is 7.34 × 10 1 copies/μL and 3.78 × 10 1 copies/μL for DHAV-1 and DAstV-3, respectively, indicating high sensitivity. A total of 34 clinical samples were tested using the established method; the positive rates for DHAV-1 and DAstV-3 was 14.71% and 8.82%, respectively, and that for co-infection was 2.94% (1/34), which was better than that obtained with conventional PCR. In summary, the SYBR Green I-based real-time PCR assay established in this study has high specificity, good sensitivity and accuracy, high feasibility, and is rapid. Thus, it can be a powerful tool for the co-infection detection of DHAV-1 and DAstV-3 and for future epidemiological studies.

Abstract
The diseases with watery droppings (diarrhea and/or polyuria) can be considered some of the most severe health problems in domestic pigeons of various ages. Although they do not always lead to bird death, they can contribute to poor weight gains and hindered development of young pigeons and, potentially, to poor racing results in sports birds. The gastrointestinal tract disorders of pigeons may be of various etiology, but some of the causative agents are viral infections. This review article provides information collected from scientific reports on RNA-viruses belonging to the Astroviridae, Picornaviridae, and Coronaviridae families; the Avulavirinae subfamily; and the Rotavirus genus that might be implicated in such health problems. It presents a brief characterization, and possible interspecies transmission of these viruses. We believe that this review article will help clinical signs of infection, isolation methods, occurrence in pigeons and poultry, systemize and summarize knowledge on pigeon enteropathogenic viruses and raise awareness of the importance of disease control in pigeons.

Abstract
Duck hepatitis A virus 3 (DHAV-3) is a wild endemic virus, which seriously endangers the duck industry in China. The present study aims to elucidate the mechanism of duck resistance to DHAV-3 infection. Both resistant and susceptible ducks were challenged with DHAV-3 in this experiment. The histopathological features and serum biochemical indices (ALT and AST) were analyzed to estimate liver injury status at 6, 12, 15, and 24 h post-infection (hpi). The dynamic transcriptomes of liver were analyzed to explain the molecular regulation mechanism in ducks against DHAV-3. The result showed that the liver injury in susceptible ducks was more serious than that in the resistant ducks throughout the four time points. A total of 2,127 differentially expressed genes (DEGs) were identified by comparing the transcriptome of the two populations. The expression levels of genes involved in innate immune response increased rapidly in susceptible ducks from 12 hpi. Similarly, the expression of genes involved in cytokine regulation also increased at the same time points, while the expression levels of these genes in resistant ducks remained similar between the various time points. KEGG enrichment analysis of the DEGs revealed that the genes involved in cytokine regulation and apoptosis were highly expressed in susceptible ducks than that in resistant ducks, suggesting that excessive cytokine storm and apoptosis may partially explain the mechanism of liver injury caused by DHAV-3 infection. Besides, we found that the FUT9 gene may contribute to resistance towards DHAV-3 in resistant ducklings. These findings will provide insight into duck resistance and susceptibility to DHAV-3 infection in the early phases, facilitate the development of a strategy for DHAV-3 prevention and treatment, and enhance genetic resistance via genetic selection in animal breeding.

Abstract
In 2019, flocks of Muscovy ducks presented with clinical signs typical of MDPV infection. The MDPV GD201911 strain was isolated by inoculating samples from positive birds into Muscovy duck embryos. Challenge with the isolate GD201911 caused typical MDPV disease symptoms and resulted in 25%-40% mortality, depending on the challenge dose, indicating the high pathogenicity of GD201911 for Muscovy ducks. Genome sequencing and phylogenetic analysis demonstrated that GD201911 clustered with recombinant MDPV strains, indicating that recombinant MDPV is circulating in China. Epidemiological monitoring should be performed continuously to assist with decision making for disease control.

Abstract
Duck hepatitis A virus type 1 (DHAV-1) disease causes significant economic losses to the duck industry. Duck enteritis virus (DEV) is frequently used as a viral vector for aquatic poultry vaccination, but no recombinan DEV expressing DHAV-1 VP0 has been developed. In this study, we established a system for rescuing the DEV C-KCE vaccine strain by transfecting cells with six fosmid DNAs. We generated a recombinant virus (rDEV-ul41VP0) by inserting the VP0 gene of DHAV-1 into the ul41 region in the DEV C-KCE genome. DHAV-1 VP0 was stably expressed in the rDEV-ul41VP0 infected cells, but did not affect the replication properties of DEV C-KCE in cells. Duck experiments showed that rDEV-ul41VP0 could provided full protection against the lethal DEV Chinese standard challenge (DEV CSC) and conferred 70% protection against DHAV-1 161/79 at 3 days postvaccination. These results indicate that rDEV-ul41VP0 rapidly induces protection against DEV CSC and DHAV-1 in ducks, and can be served as a bivalent vaccine against DEV and DHAV-1.

Abstract
Duck hepatitis A virus (DHAV) causes acute hepatitis and mortality, resulting in high economic losses in the duck farm industry. The current study describes the outbreak of DHAV in vaccinated duck farms in North Egypt during 2019 and molecular characterization of the 3' untranslated region (UTR) and viral protein VP1 genes. The 30 samples were collected from 7- to 28-day-old commercial Pekin ducks that showed a history of nervous signs and sudden deaths and were on farms in 6 governorates. DHAV was typed by reverse transcription-polymerase chain reaction (RT-PCR) for 3' UTR and VP1 genes and revealed 20 positive farms, with the first detection of DHAV genotype 3 (DHAV-3) in 18 samples and the classic DHAV-1 in 2 samples. The phylogenetic analysis of VP1 and 3' UTR genes of the nine selected strains representative of six governorates revealed that seven strains were clustered with DHAV-3 Chinese and Korean-Vietnamese strains within different subgroups with 92.4%-93.7% amino acid identity; such strains were distinguishable from the vaccine strain of DHAV-1 used in Egypt with 74.4% amino acid identity. The other strains were closely related to the DHAV-1 Asian strain and the vaccine strain used in Egypt with 98.7%-99.6% amino acid identity for the VP1 gene with different clustering than that of recently isolated DHAV-1 Egyptian strains. The VP1 gene of DHAV-3 had 1 hypervariable region (HVR) with 10 amino acid mutations compared with DHAV3/DN2/Vietnam/2011, but DHAV-1 had 3 HVRs with 1 amino acid mutation in HVRII compared with the DHAV-1 vaccine strain. In conclusion, a new introduction of DHAV-3 with the classical DHAV-1 was recorded in Pekin duck farms in North Egypt that is genetically distant from the vaccinal strain.

Abstract
Duck hepatitis A virus genotypes 3 (DHAV-3) has become the most prevalent pathogen of duck viral hepatitis (DVH) in Asian duck industry in recent years. Previous studies on the pathogenic mechanism of DHAV-3 mainly focused on examine host gene expression levels. However, the study about host protein expression levels has not been reported. For this, proteomics analysis on livers of infected 7-day-old Pekin ducks with DHAV-3 112803 strain was performed to screen differentially expressed proteins. A total of 3,385 proteins were identified, and we found 39 proteins in the challenged group (CH) were significantly up-regulated and 15 proteins were significantly down-regulated in comparison with control group (CON). GO results showed that 9 of the top 20 GO terms were involved in type I interferon regulation, and the KEGG pathway enrichment results showed that innate immune responses were significantly enriched, such as RIG-1-like, Toll-like and NOD-like receptor signaling pathways. Notably, interaction between 11 up-regulation proteins promoted interferon-induced protein synthesis and supported viral genome replication, which could aggravate inflammatory response and liver damage. These findings, together with RT-qPCR verification of related genes, support the view that the type I interferon may play an extremely important role in the pathogenic mechanism of DHAV-3.

Abstract
Duck hepatitis A virus (DHAV) causes a highly contagious and acute disease in ducklings younger than 3 weeks of age and spreads rapidly by horizontal transmission to all susceptible ducklings in the flock. To date, there is no evidence of vertical transmission of DHAV-1. In a previous study, we identified a novel DHAV type 1 (DHAV-1) isolate that could infect adult ducks and induce laying drop. In this study, 30 non-embryonated duck eggs and 60 17-day-old embryos were collected from three breeding duck flocks with egg drop syndrome caused by DHAV-1 in China, and 30 17-day-old embryos were randomly selected from the 60 embryos and allowed to hatch. DHAV-1 RNA was detected by RT-PCR in 10 of 30 non-embryonated eggs, 9 of 30 17-day-old embryos, 5 of 7 dead embryos and 5 of 23 newly hatched ducklings. Overall, 29 of 90 (32.2%) eggs and embryos were positive for DHAV-1. Three DHAV-1 strains were isolated from the dead duck embryos of the three breeding duck flocks, respectively. Pathogenicity studies showed that the three DHAV-1 isolates had median embryo lethal doses but were highly pathogenic to healthy ducklings. Compared with the DHAV reference strains, there were two specific amino acid mutation sites (F169 and S220 ) in VP1 of the three isolates. To the best of our knowledge, this is the first report that DHAV-1 is isolated from duck embryos. The findings provide evidence of possible vertical transmission of DHAV-1 from breeding ducks to ducklings.

Abstract
An indirect enzyme-linked immunosorbent assay (I-ELISA) based on the VP2 protein of duck hepatitis A virus type 3 (DHAV-3) was established in this study. The optimal dilutions of antigen, serum and goat anti-duck IgG conjugate were 1:1600 (2.23 μg/mL), 1:160 and 1:2000, respectively. The optimal blocking buffer was 1% skim milk. The cut-off value for the method was 0.25, and the analytical sensitivity of the method was 1:5120. The results of specific evaluation showed that except for DHAV-1, DHAV-3 antisera did not cross-react with any other common duck-sensitive pathogens, indicating that this method can be used to detect DHAV-3 and DHAV-1 antibodies. The coefficients of variation (CVs) were lower than 10 %. The coincidence rate between the VP2-DHAV-3-ELISA and the neutralization test was 93.3 %. In summary, the I-ELISA method based on VP2 protein has high sensitivity, specificity, and coincidence rate compared with the neutralization test and has advantages in serum monitoring. The I-ELISA method based on VP2 protein provides a simple and rapid method for the detection of anti-DHAV antibodies and the epidemiological monitoring of DHAV.

Abstract
Duck hepatitis A virus type 3 (DHAV-3) is an important pathogen that causes substantial losses in the Chinese duck industry. DHAV-3 is highly fatal to ducklings and there is no licensed vaccine in China available to reduce DHAV-3 infection. Our goal was to develop a live attenuated vaccine candidate against DHAV-3. A field isolated strain, SD, was attenuated by serially passaging in specific-pathogen-free (SPF) chicken embryos, and it lost its pathogenicity after 40 passages. The 70th passaged strain (SD70), which achieved good growth capacity in chicken embryos with a viral titer of 107.5 ELD50/mL, was chosen to be the live attenuated vaccine candidate. The SD70 strain did not cause clinical signs of disease or mortality in 1-day-old ducklings and showed no virulence reversion after seven rounds of in vivo back passages. The minimum effective dose of SD70 was determined to be 102.5 ELD50 via the vaccination route of subcutaneous inoculation. A single dose of the SD70 provided good protection to susceptible ducklings against the lethal DHAV-3 strain. Compared with the genomic sequence of the parent SD strain, the SD70 had 12 amino acid substitutions, some of which may play a role in virulence attenuation. This study demonstrated that the attenuated SD70 strain is a promising vaccine candidate for the prevention of DHAV-3 infection in China. It exhibited safety, good stability and excellent protection.

Abstract
Duck hepatitis virus (DHV) has always been considered one of the threats endangering duck farming in Egypt since the 1960s. In the current study, suspected DHV samples (n = 30) were obtained from commercial Pekin, Mulard (hybrid), and Muscovy duck farms and backyards in Beheira, Alexandria, Gharbia, Kafr El-Sheikh, and Giza provinces between 2012 and 2017. Diseased 3–21-day-old ducklings showed a clinical history of high mortality rates and nervous signs. Samples were screened by RT-PCR targeting the 5′UTR region and VP1 gene. The PCR-confirmed samples (n = 7) were isolated via allantoic route inoculation onto 9-day-old specific-pathogen-free embryonated chicken eggs. Embryos showed stunting, subcutaneous hemorrhages, and liver necrotic greenish-yellow foci. Duck hepatitis A virus-1 (DHAV-1) isolates were genetically analyzed in comparison to other field and vaccine strains. Phylogenetic analyses of the full-length VP1 gene sequences revealed that the obtained DHAV-1 field isolates clustered into genetic group 4 alongside other Egyptian strains isolated during the same period (95.9–99.72% similarity). Amino acid substitutions in the carboxyl-terminal of VP1 (I180T, G184E, D193N, and M213I) were identified in two strains. Also, deletion mutation at I189 was detected in three DHAV-1 strains. Additionally, the two amino acid residues E205 and N235 were common among the isolated strains and other virulent DHAV-1 strains. Two DHAV-1 isolates originated from Pekin source were selected for conducting the comparative pathogenicity testing based on detected point mutations at C-terminus of VP1. We evaluated the pathogenicity of these isolates by investigating clinical signs, mortality rates, and gross pathological and microscopic lesions. The study revealed that experimentally infected Pekin and Muscovy ducklings showed similar clinical signs including squatting down, lateral recumbency, and spasmodic kicking. Muscovy showed milder pathological changes in the liver compared to Pekin ducklings. Histopathological findings supported the gross pathological lesions detected in both breeds. In conclusion, these data provide updated information on the genetic diversity and pathotyping of Egyptian DHAV-1 strains. To the best of our knowledge, this is the first report of comparative pathogenicity of recent DHAV-1 strains in Pekin and Muscovy ducklings in Egypt and the Middle East region.

Abstract
Duck hepatitis A virus (DHAV) is one of the pathogens that cause fatal duck viral hepatitis (DVH) in ducklings, which is an acute and contagious disease with a high mortality rate. Despite a continuing official duck vaccination program, DHAV infection remains a major threat to the duck industry. Considerable changes were observed in the epidemiology of DHAV-1/-3 in China over time. Therefore, comparing the pathogenicity of different DHAV serotypes can provide a theoretical basis for the diagnosis and prevention of DVH. In this study, we systematically investigated the effects of infection with DHAV-1/-3 field strains on clinical signs, gross lesions, histopathological changes, viral RNA detection, enzymatic systems, and metabolite concentrations. The results demonstrated that the major macroscopic and microscopic lesions in ducks infected with DHAV-1/-3 in the liver, brain, spleen, pancreas, and kidneys exhibited no significant differences. After 24 h of infection, DHAV quickly appeared in blood and major organs. Significant changes in clinical chemical markers together with histopathological lesions and viral RNA detection indicated that the liver is the major target organ for both viruses, resulting in impaired of liver integrity and function. In addition, we found that both viruses were able to invade both central and peripheral immune organs. Also lipase plasma activity was substantially affected by DHAV-1/-3, indicating that the integrity and function of the pancreas was compromised. However, there was no significant difference in pathogenicity between DHAV-1 and -3. The results of this study provide new insights into the pathogenesis of DHAV-1/3, two viruses that cause serious depression, metabolic disorders, and immunosuppression.

Abstract
Earlier works identified the second generation (Z8R2) of a resistant Pekin duck line to duck hepatitis A virus genotype 3 (DHAV-3), which displays significantly strong resistance than that of the second generation (Z8S2) of a susceptible Pekin duck line. To understand the genetic mechanisms that determine the different resistance/susceptibility of Z8R2 and Z8S2 to DHAV-3, transcriptome analysis on livers of infected Pekin ducklings was performed to screen differentially expressed genes (DEGs). We found that DHAV-3 infection has a great effect on metabolism of Z8S2 at the transcription level. Using a newly created fourth generation of the resistant Pekin duck line (Z8R4) and an unselected Pekin duck flock (Z7) as models, hypoglycemia and dramatically increased aspartate aminotransferase and alanine aminotransferase were shown to be noticeable signs of fatal cases caused by DHAV-3 infection. These findings, together with expression analysis and verification of DEGs, support the view that DHAV-3 infection results in glucose metabolic abnormalities in susceptible individuals and that there are significant differences in expression patterns of glucose metabolism-related DEGs between susceptible and resistant individuals. Notably, cytokines displayed a negative correlation with glucose synthesis in terms of expression in susceptible individuals following DHAV-3 infection. Mechanism analyses suggests that cytokines will activate PI3K-AKT pathway and/or JAK-STAT pathway by up-regulated expression of JAK2, and thereby causes down-regulated expression of G6PC and/or ACAT1. Cytokines can also cause down-regulated expression of HPGDS by JAK2. The present work contributes to the understanding of pathogenesis of DHAV-3 infection and the resistance breeding project against DHAV-3.

Abstract
During 2015, duck farms (n = 27) in Sharkia Province, Egypt, experienced several disease outbreaks leading to mortality and nervous manifestations. Upon necropsy, the affected ducklings showed liver lesions, such as hemorrhage or necrosis, suggestive of duck virus hepatitis (DVH). Reverse transcription-PCR (RT-PCR), on the basis of the 3D gene, found duck livers from 21 farms to be positive for duck hepatitis A virus serotype 1 (DHAV-1). All duck breeds (Pekin, Mallard, and Muscovy) were infected. The virus was isolated in embryonated chicken eggs, which showed embryonic mortality (40%-80%) within 5-7 days, stunting or dwarfing (69.6%), and necrotic liver foci (60.9%). The VP1 gene of 11 DHAV-1 strains was characterized by RT-PCR and Sanger sequencing. All study strains were clustered in a monophyletic branch within subclade B2 of Group 4 and were separated from the Egyptian vaccine strain. Several amino acid (aa) residues, such as V129, S142 (only in four strains), L181, G184, and K217, were related to virus attenuation. However, two aa residues (N193 and E205), found in virulent DHAV-1 strains, were also observed in our strains. This study confirms the circulation of DHAV-1 (subclade B2) in Lower Egypt and elucidates the phylogenetic characters of the VP1 genes, which will be useful in following the local trends of DHAV-1 infections. Further studies are indicated to determine the correlation between these mutations and the virulence of the Egyptian DHAV-1 isolates.

Abstract
In industrialized countries, hepatitis E is now recognized as an emerging zoonosis. Autochthonous cases have been increased over recent years in Europe and are mainly associated with HEV-3 infections. Pigs and wild boars are considered the main reservoirs of the zoonotic HEV-3 and HEV-4 genotypes. Over the past decade, the number of wild boars has drastically increased in Europe. Due to habitats closer to humans and domestic animals, the role of wild boar as a reservoir of the zoonotic HEV is considered to be an emerging issue. In this study, we investigated the presence of HEV RNA by a real-time RT-PCR assay in paired liver and muscle samples collected from 196 wild boars (Sus scrofa) hunted in the two areas of Central and Southern Italy. Twenty animals (10.2%) were HEV RNA positive in livers, 11 of which were also positive in muscles. The ORF2 and ORF1 partial viral sequences were obtained for nine paired livers and muscles, and when aligned were identical to each other. Phylogenetic analyses confirmed detection of different HEV-3 subtypes: 3c, 3f, 3i and some that were not assigned to any subtypes that have so far been identified. Results need further investigation because they are based on analyses of sequences of short genome regions. Nevertheless, we observed that the same strains were circulating in the wild boar populations from the two investigated areas, confirming persistence of the same HEV strains in the wild boar population over time.

Abstract
Background Duck hepatitis A virus type 3 (DHAV-3) is one of the most harmful pathogens in the duck industry. However, the molecular mechanism underlying DHAV-3 infection in ducklings remains poorly understood. To study the genetic regulatory network for miRNA-mRNA and the signaling pathways involved in DHAV-3 infection in ducklings, we conducted global miRNA and mRNA expression profiling of duckling liver tissues infected with lethal DHAV-3 by high-throughput sequencing. Results We found 156 differentially expressed miRNAs (DEMs) and 7717 differentially expressed genes (DEGs) in livers of mock-infected and DHAV-3-infected duckling. A total of 19,606 miRNA-mRNA pairs with negatively correlated expression patterns were identified in miRNA-mRNA networks constructed on the basis of these DEMs and DEGs. Moreover, immune-related pathways, including the cytokine-cytokine receptor interaction, apoptosis, Toll-like receptor, Jak-STAT, and RIG-I-like receptor signaling pathway, were significantly enriched through analyzing functions of mRNAs in the network in response to DHAV-3 infection. Furthermore, apl-miR-32-5p, apl-miR-125-5p, apl-miR-128-3p, apl-miR-460-5p, and novel-m0012-3p were identified as potential regulators in the immune-related signaling pathways during DHAV-3 infection. And some host miRNAs were predicted to target the DHAV-3 genome. Conclusions This is the first integrated analysis of miRNA and mRNA in DHAV-3-infected ducklings. The results indicated the important roles of miRNAs in regulating immune response genes and revealed the immune related miRNA-mRNA regulation network in the DHAV-3-infected duckling liver. These findings increase our knowledge of the roles of miRNAs and their target genes in DHAV-3 replication and pathogenesis. They also aid in the understanding of host-virus interactions.

Abstract
Hepatitis E is an emerging threat in industrialized countries. The foodborne transmission linked to consumption of pork and game meat is considered the main source of autochthonous infection. In Europe, small outbreaks have been reported linked to the consumption of pork liver sausages and wild boar meat. Based on previous findings and on increasing evidence of pork and game meat as a vehicle for HEV infections, the present study investigated the occurrence of HEV in 99 pork and 63 wild boar sausages and salami sold in Southern Italy. The HEV genome was detected in four wild boar sausages. Sequencing from 2 wild boar sausages confirmed that the HEV strains detected belonged to HEV-3 genotype, not assigned to any defined subtype. Data obtained confirmed the possible occurrence of HEV in pork products and in game. Although the detection rate is low, these products are frequently consumed raw after curing, whose effect on virus viability is still unknown.

Abstract
Duck hepatitis A virus (DHAV) causes an infectious disease that mainly affects 1- to 4-week-old ducklings, resulting in considerable loss to the duck industry. Although there have been many studies on DHAV in recent years, the effects on host infection and pathogenesis of DHAV-1 remain largely unknown. This study investigated the effects of the DHAV-1 structural protein VP3 on DHAV-1 virus adsorption and apoptosis to explore the role of VP3 in the viral life cycle. The effects of DHAV-1 VP3 and an antibody against the protein on virion adsorption was analyzed by qRT-PCR. The results showed that the virus copy number for the rabbit anti-VP3 IgG-treated group was significantly lower than that for the negative control group but higher than that for the rabbit anti-DHAV-1 IgG-treated group. This result indicates that VP3 mediates DHAV-1 virus adsorption but that it is not the only protein that involved in this process. In addition, a eukaryotic recombinant plasmid, pCAGGS/VP3, was transfected into duck embryo fibroblasts (DEFs), and the apoptotic rate was determined by DAPI staining, the TUNEL assay and flow cytometry. DAPI staining showed nucleus fragmentation and nuclear edge shifting. TUNEL assay results revealed yellow nuclei, and flow cytometry indicated a significant increase in the apoptotic rate. In addition, qRT-PCR revealed increased in the transcriptional levels of the apoptotic caspase-3, −8 and −9, with the largest increase for caspase-3, followed by caspase-9 and caspase-8. Enzyme activity analysis confirmed these results. Furthermore, the VP3 protein decreased the mitochondrial membrane potential, and the transcriptional levels of the proapoptotic factors Bak, Cyt c and Apaf-1 in the mitochondrial apoptotic pathway were significantly upregulated. These data suggest that expression of VP3 in DEFs induces apoptosis and may primarily activate caspase-3-induced apoptosis through mitochondrion-mediated intrinsic pathways. The findings provide scientific data to clarify DHAV-1 infection and pathogenesis.

Abstract
Duck hepatitis A virus (DHAV) is prevalent worldwide and has caused significant economic losses. As the predominant serotype in China, DHAV-3 has become a major challenge to the local duck industry. Here the genetics and pathogenesis of a virulent DHAV-3 strain and its embryo-passaged strain were assessed. There were only two amino acid substitutions (Y164N in VP0 protein and L71I in 2C protein) introduced during the adaptation process. The pathogenicity of these strains was further evaluated in vivo. Clinical signs, gross pathology, and histopathological analysis showed that the embryo-passaged strain was attenuated. Meanwhile, the viral RNA loads were significantly lower in the liver tissues of the ducklings infected with the attenuated strain. As expected, infection with the virulent and attenuated strains led to the activation of different innate immune genes. We suspected that the loss of replication efficiency in ducklings was responsible for the attenuation phenotype of the embryo-passaged strain. In addition, different innate immune responses in the liver of ducklings were at least partly responsible for the differential infectivity phenotype. These findings provide new insights into the genetics and pathogenesis of DHAV-3, which may aid the development of new vaccines and the implementation of immunization strategies.

Abstract
Duck hepatitis A virus (DHAV) infection is characterized by severe hepatitis. In recent
years, DHAV-A has become widespread in Asia and has led to economic losses. Conventional
methods of DHAV-A detection must often be performed in the laboratory with inconvenience
equipment. We have developed a rapid reverse transcription insulated isothermal (RT-iiPCR)
technique for the on-site detection of DHAV-A based on the POCKITTM system in a
convenient minitype device. We optimized the PCR primers and probes for the amplification
of the DHAV-A 3C/3D genes, and successfully amplified a specific fragment of DHAV-A, but
no fragment from 18 other duck pathogens. The limit of detection for viral RNA was 49
copies per reaction, and the sensitivity and specificity were each 100% in the analysis of
60 liver samples. By comparison, the sensitivities of RT-iiPCR was comparable in
sensitivity to existing rRT-PCR. Furthermore, the RT-iiPCR results were 98.3% in agreement
with those of the rRT-PCR, with a kappa value of 0.938. In conclusion, this new method not
only offers a higher sensitivity and specificity than existing techniques, but also
time-saving and better suited to field diagnoses because device is portable.

Abstract
Duck hepatitis A virus type 3 (DHAV-3) infection is characterized by severe hepatitis. In recent years, DHAV-3 has become widespread in Asia and has led to economic losses. Conventional methods for DHAV-3 detection usually depend on the use of larger equipment that is not portable and is not fit for on-site diagnoses. In this study, a rapid reverse transcription insulated isothermal (RT-iiPCR) technique was developed for the on-site detection of DHAV-3 based on the POCKIT™ system in a convenient device. The concentration of primer pairs and probes were optimized for amplification of the DHAV-3 VP3 gene of DHAV-3, with no amplification of 12 other duck pathogens. The detection limit of viral RNA was 3.85 × 101 copies/μL, and the analytical sensitivity and specificity levels were both 100% in the detection of 40 liver samples. Furthermore, 97.5% of the RT-iiPCR results were in agreement with those of rRT-PCR, with a kappa value of 0.93.

Abstract
BACKGROUND The picornaviral 3C protease mediates viral polyprotein maturation and multiple cleavages of host proteins to modulate viral translation and transcription. The 3C protease has been regarded as a valid target due to its structural similarity among different picornaviruses and minimal sequence similarity with host proteins; therefore, the development of potent inhibitors against the 3C protease as an antiviral drug is ongoing. Duck hepatitis A virus (DHAV) belongs to the Picornavidea family and is a major threat to the poultry industry. To date, little is known about the roles of the DHAV 3C protease plays during infection. METHODS In this study, we compared the full-length DHAV 3C protein sequence with other 3C sequences to obtain an alignment for the construction of a phylogenetic tree. Then, we expressed and purified recombinant DHAV 3C protease in the BL21 expression system using nickel-NTA affinity chromatography. The optimization of the cleavage assay conditions and the kinetic analysis for DHAV 3C protease were done by in vitro cleavage assays with a fluorogenic peptide respectively. The inhibitory activity of rupintrivir against the DHAV 3C protease was further evaluated. The localization of the 3C protease in infected and transfected cells was determined using immunofluorescence and confocal microscopy. RESULTS Under different expression conditions, the 3C protease was found to be highly expressed after induction with 1 mM IPTG at 16 °C for 10 h. We synthesized a fluorogenic peptide derived from the cleavage site of the DHAV polyprotein and evaluated the protease activity of the DHAV 3C protease for the first time. We used fluorimetric based kinetic analysis to determine kinetic parameters, and Vmax and Km values were determined to be 16.52 nmol/min and 50.78 μM, respectively. Rupintrivir was found to exhibit inhibitory activity against the DHAV 3C protease. Using polyclonal antibody and an indirect immunofluorescence microscopy assay (IFA), it was determined that the DHAV 3C protease was found in the nucleus during infection. In addition, the DHAV 3C protease can enter into the nucleus without the cooperation of viral proteins. CONCLUSIONS This is the first study to examine the activity of the DHAV 3C protease, and the activity of the DHAV 3C protease is temperature-, pH- and NaCl concentration- dependent. The DHAV 3C protease localizes throughout DHAV-infected cells and can enter into the nucleus in the absence of other viral proteins. The kinetic analysis was calculated, and the Vmax and Km values were 16.52 nmol/min and 50.78 μM, respectively, using the Lineweaver-Burk plot.

Abstract
Duck hepatitis A virus type 1 (DHAV-1) is one of the most lethal pathogens in the duck industry. The attenuated vaccine (the CH60 strain) is cultivated through serial passage in chicken embryos and is widely used for the prevention and control of the disease. However, the specific mechanism underlying its adaptation in chicken embryos has not been fully elucidated. In this study, we first infected chicken embryo fibroblasts (CEFs) with the DHAV-1 CH60 strain. The peak of viral proliferation occurred within 36–48 h post-infection. The different DHAV-1 strains significantly induced the expression of IFNα, IFNγ, and Suppressor of cytokine signaling 3 (SOCS3) in CEFs, and we found that SOCS3 overexpression significantly promoted viral replication. Furthermore, SOCS3 overexpression significantly inhibited the expression of IFNα but promoted the expression of IFNγ. In addition, SOCS3 overexpression clearly decreased the mRNA levels of STAT1 and STAT3 in the Janus kinase (JAK)-STAT signaling pathway and inhibited the expression of the antiviral proteins MX1 and OASL. Immune-precipitation assays indicated that SOCS3 and IFNα do not physically interact. Subcellular localization of SOCS3 and IFNα revealed that SOCS3 was mainly located in the nucleus and cytoplasm, while IFNα was located only in the cytoplasm. Co-localization of these two proteins was not observed in the cytoplasm. In conclusion, the DHAV-1 CH60 strain may inhibit the expression of IFNα by increasing the SOCS3 protein and SOCS3 can in turn decrease STAT1 and STAT3 mRNA levels, thereby inhibiting the antiviral protein MX1 and ultimately promoting viral proliferation, indirectly assisting in viral adaptation in chicken embryos.

Abstract
To develop an indirect enzyme-linked immunosorbent assay(I-ELISA) method based on 3A protein of duck hepatitis A virus type 1(DHAV-1) for detection of DHAV-1 antibody, the recombinant protein 3A of DHAV-1 was expressed in E.coli and detected by Western blotting with DHAV-1 infected duck serum. A 3A-ELISA method using the expressed 3A protein as coating antigen for the detection of antibodies to DHAV-1 was developed. The optimal antigen, serum and enzyme-labeled antibody dilutions were 1:200(6.185 μg/ml), 1:20 and 1:2000, respectively. The optimal blocking buffer was 5% BSA. The cutoff value was determined to be 0.274, and the analytical sensitivity was 1:1280. There was no cross reaction between DHAV-1 infected duck serum and other common pathogenic duck serum, indicating that I-ELISA could be used to detect DHAV-1 infected duck serum. The coefficients of variation(CVs) were lower than 10%. The concordance between the I-ELISA based on the 3A subunit of DHAV-1 and that based on the whole DHAV-1 particle was 92.7%. Taken together, the 3A-ELISA method is a highly sensitive and specific test that could be used for screening for DHAV-1 infection and monitoring DHAV-1 antibody.
