Abstract
Using marker vaccines to control bovine alphaherpesvirus-1 (BoHV-1) is a novel strategy for differentiation between infected and vaccinated animals (DIVA). In this study, multiplex real-time PCR targeting gD and gE genes was applied for BoHV-1 screening on 60 clinical samples from cattle with a history of vaccination, in some cases by US2-deleted marker vaccines, that were suffering from severe respiratory symptoms. Conventional PCR targeting the gC and US2 flanking region was done for molecular characterization and identification of the US2-deleted vaccine strain. Six samples were positive for BoHV-1 by both RT-PCR and conventional PCR. Surprisingly, a conventional PCR DIVA trial based on the US2 gene revealed that only one sample that exhibited the US2 gene was a wild virus, while others that did not exhibit the US2 gene were vaccine viruses. Phylogenetic characterization classifies the samples as BoHV-1.1. This finding reveals the circulation of vaccine virus in field-diseased animals, which threatens the eradication program.

Abstract
Three outbreaks of herpesvirus meningoencephalitis in cattle have been reported in three municipalities in the northern region of the State of Tocantins, Brazil. In one outbreak, 41 predominantly young bovines were affected, with 2-3 deaths in some cases. The animals showed neurological signs of incoordination, blindness, and recumbency, with death occurring within approximately 4-5 d. At necropsy, hyperemia and leptomeningeal hemorrhages were observed in the brain. Histology revealed more intense lesions in the rostral portions of the brain, mainly affecting the frontoparietal cerebral cortex, with nonsuppurative encephalitis and meningitis, glial nodules, neuronophagia, and eosinophilic intranuclear inclusion bodies in the astrocytes and neurons. This study shows the presence of bovine herpesvirus in Tocantins, probably the highly neurotropic type 5 strain, and emphasizes its importance in the differential diagnosis of bovine neuropathies.

An indirect ELISA to detect antibodies to the gC of bovine alphaherpesvirus 1 (BoAHV1) displaying no crossreactivity with antibodies induced by bovine alphaherpesvirus 5 (BoAHV5). J Virol Methods 2023; 320:114785.

Abstract
Seroprevalence of bovine alphaherpesvirus type 1 (BoAHV1) infections may be contaminated by crossreactive antibodies to bovine alphaherpesvirus type 5 (BoAHV5). To avoid such crossreactivity, an indirect enzyme-linked immunosorbent assay prepared with a recombinant glycoprotein C (gC) antigen (ELISA-gC1) was developed, aiming the detection of antibodies to BoAHV1, with no crossreactivity with BoAHV5 antibodies. The antigen for the ELISA-gC1 was the product of the expression of 219 bp from the N-terminal portion of the BoAHV1 gC gene, which bears low homology between the two virus types. The test was validated on 131 bovine serum samples, including 26 sera from BoAHV1-experimentally immunized, 38 sera from BoAHV5-experimentally infected or immunized calves, and 67 sera from calves seronegative for both BoAHV1 and BoAHV5, as determined by serum neutralization (SN). When compared to SN for BoAHV1, the ELISA-gC1 presented 100% sensitivity, 95.5 % specificity, 100 % negative predictive value, 89.6 % positive predictive value, 98.8 % precision, and a kappa correlation coefficient (κ) 0.95. None of the 38 BoAHV5-seropositive calves was detected by the ELISA-gC1. The ELISA-gC1 proved highly effective for the identification of BoAHV1-positive sera, with no crossreactivity with anti-BoAHV5 antibodies, thus able to distinguish serological responses from BoAHV1- and BoAHV5-seropositive cattle. Its capacity to detect BoAHV1-specific antibodies should allow the determination of the actual BoAHV1 prevalence in herds, which cannot be serologically determined in countries where BoAHV5 is also prevalent due to antibody crossreactivity. Apart from recognizing exclusively BoAHV1-infected cattle, the ELISA-gC1 may also be used in support of BoAHV5 epidemiological studies by allowing the exclusion of BoAHV1-seropositive animals.

Neutralizing antibodies to bovine and bubaline alphaherpesviruses in water buffaloes (Bubalus bubalis). Braz J Microbiol 2023; 54:1231-1237.

Abstract
Water buffaloes (Bubalus bubalis) have been introduced in many regions of the world as a source of animal protein. In many instances, bubaline cattle are reared close to or mixed with bovine or zebuine cattle. However, little is known about infectious diseases of bubaline and the interactions that may arise involving the microbiota of those species. Alphaherpesviruses of ruminants (bovine alphaherpesviruses types 1 and 5, BoHV-1, BoHV-5; bubaline alphaherpesvirus 1, BuHV-1) are highly cross-reactive in serological assays performed with bovine or zebuine sera. However, the profile of reactivity of bubaline cattle sera to alphaherpesviruses remains unknown. As such, it is not known which virus strain (or strains) would be most appropriate to be used as the challenge virus in the laboratory in search for alphaherpesvirus-neutralizing antibodies. In this study, the profile of neutralizing antibodies to alphaherpesviruses in bubaline sera was determined against different types/subtypes of bovine and bubaline alphaherpesviruses. Sera (n=339) were screened in a 24-h serum neutralization test (SN) against 100 TCID50 of each of the challenge viruses. From those, 159 (46.9 %) neutralized at least one of the viruses assayed; 131 (38.6%) sera neutralized the three viral strains used for screening. The viral strain that was neutralized by the largest number of sera was BoHV-5b A663 (149/159; 93.7%). A few sera neutralized only one of the challenge viruses: four sera neutralized BoHV-1 LA only; another neutralized BoHV-5 A663 only and four others neutralized BuHV-1 b6 only. SN testing with two additional strains gave rise to similar results, where maximum sensitivity (defined here as the largest number of sera that neutralized the challenge viruses) was obtained by adding positive results attained with three of the challenge strains. Differences in neutralizing antibody titers were not significant to allow inferences on which would be the most likely virus that induced the antibody responses detected here.

Abstract
BoHV-5 is a worldwide distributed pathogen usually associated with a lethal neurological disease in dairy and beef cattle resulting in important economic losses due to the cattle industry. Using recombinant gD5, we evaluated the long-duration humoral immunity of the recombinant vaccines in a cattle model. Here we report that two doses of intramuscular immunization, particularly with the rgD5ISA vaccine, induce long-lasting antibody responses. Recombinant gD5 antigen elicited tightly mRNA transcription of the Bcl6 and the chemokine receptor CXCR5 which mediate memory B cells and long-lived plasma cells in germinal centers. In addition, using an in-house indirect ELISA we observed higher and earlier responses of rgD5-specific IgG antibody and the upregulation of mRNA transcription of IL2, IL4, IL10, IL15, and IFN-γ in rgD5 vaccinated cattle, indicating a mixed immune response. We further show that rgD5 immunization protects against both BoHV -1 and -5. Our findings indicate that the rgD5-based vaccine represents an effective vaccine strategy to induce an efficient control of herpesviruses.

Abstract
Bovine alphaherpesviruses 1 and 5 (BoHV-1 and BoHV-5) are closely related viruses that co-circulate in South America and recombine in the field. The complete genomes of three natural gB gene recombinant viruses between BoHV-1 and BoHV-5 were obtained by Illumina next-generation sequencing. Complete genome sequences of the three recombinant strains (RecA1, RecB2, and RecC2) have a similar size of approximately 138.3kb and a GC content of 75%. The genome structure corresponds to herpesvirus class D, with 69 open reading frames (ORFs) arranged in the same order as other bovine alphaherpesviruses related to BoHV-1. Their genomes were included in recombination network studies indicating statistically significant recombination evidence both based on the whole genome, as well as in the sub-regions. The novel recombinant region of 3074 nt of the RecB2 and RecC2 strains includes the complete genes of the myristylated tegument protein (UL11) and the glycoprotein M (UL10) and part of the helicase (UL9) gene, and it seems to have originated independently of the first recombinant event involving the gB gene. Phylogenetic analyzes performed with the amino acid sequences of UL9, UL 10, and UL11 indicated that RecB2 and RecC2 recombinants are closely related to the minor parental virus (BoHV-1.2b). On the contrary, RecA1 groups with the major parental (BoHV-5), thus confirming the absence of recombination in this region for this recombinant. One breakpoint in the second recombinant region lies in the middle of the UL9 reading frame, originating a chimeric enzyme half encoded by BoHV-5 and BoHV-1.2b parental strains. The chimeric helicases of both recombinants are identical and have 96.8 and 96.3% similarity with the BoHV-5 and BoHV-1 parents, respectively. In vitro characterization suggests that recombinants have delayed exit from the cell compared to parental strains. However, they produce the similar viral titer as their putative parents suggesting the accumulation of viral particles for the cell exit delayed on time. Despite in vitro different behavior, these natural recombinant viruses have been maintained in the bovine population for more than 30 years, indicating that recombination could be playing an important role in the biological diversity of these viral species. Our findings highlight the importance of studying whole genome diversity in the field and determining the role that homologous recombination plays in the structure of viral populations. A whole-genome recombinant characterization is a suitable tool to help understand the emergence of new viral forms with novel pathogenic features.

Abstract
Neurotrophic factors have been implicated in the control of neuronal survival and plasticity in different brain diseases. Meningoencephalitis caused by bovine alpha-herpesvirus 5 (BoHV-5) infection is a frequent neurological disease of young cattle, being the involvement of apoptosis in the development of neuropathological changes frequently discussed in the literature. It's well known that Toll-like receptors (TLRs) can activate neuroinflammatory response and consequently lead to neuronal loss. However, there are no studies evaluating the expression of neurotrophic factors and their association with brain pathology and TLRs during the infection by BoHV-5. The current study aimed to analyze brain levels of neurotrophic factors along with neuropathological changes during acute infection by BoHV-5 in wild-type (WT) and TLR3/7/9 (TLR3/7/9-/-) deficiency mice. The infection was induced by intracranial inoculation of 1 × 104 TCID50 of BoHV-5. Infected animals presented similar degrees of clinical signs and neuropathological changes. Both infected groups had meningoencephalitis and neuronal damage in CA regions from hippocampus. BoHV-5 infection promoted the proliferation of Iba-1 positive cells throughout the neuropil, mainly located in the frontal cortex. Moreover, significant lower levels of brain-derived neurotrophic factor (BDNF) were detected in both BoHV-5 infected WT and TLR3/7/9 deficient mice, compared with non-infected animals. Our study showed that BDNF down regulation was associated with brain inflammation, reactive microgliosis and neuronal loss after bovine alpha-herpesvirus 5 infection in mice. Moreover, we demonstrated that combined TLR3/7/9 deficiency does not alter those parameters.

Abstract
Bovine herpesvirus 5 (BoHV-5) is a pathogen of cattle responsible for fatal meningoencephalitis. Like alpha herpesvirus subfamily members, BoHV-5 also encodes microRNA in lytic infections of epithelial cells. BoHV-5-miR-B10 was the most abundant miRNA detected in a high-throughput sequencing study. Here, we evaluated the kinetics of miR-B10 expression after BoHV-5 productive infection by stem-loop real-time quantitative PCR. miR-B10 candidate target sites in the virus were predicted, and BoHV-5 UL39 was confirmed as a target gene by dual-luciferase assay with the design of an miR-B10 tough decoy (TuD). The UL39 gene encoding ribonucleotide reductase (RR) large subunit plays an important role in the early stage of BoHV-5 lytic infection. As BoHV-5-miR-B10 is located in internal and terminal repeat regions, we generated a TuD gene-integrated BoHV-5 strain, which effectively down-regulated miR-B10-3p. Strikingly, the suppression of miR-B10-3p significantly improved BoHV-5 replication. Taking these findings together, our study established an efficient method to deliver and express TuD RNA for viral miRNA suppression, and demonstrated that virus-encoded miRNA suppresses viral-genome biogenesis with a feedback mode, which might serve as a brake for viral replication. Herpesviruses infect humans and a variety of animals. Almost all herpesviruses can encode miRNAs, but the functions of these miRNAs remain to be elucidated. Most herpesvirus-encoded miRNA harbours dual copies, which is difficult to be deleted by current genetic modulation. Here, we developed an efficient method to deliver and express TuD RNA to efficiently suppress viral miRNA with multiple copies. Using this method, we demonstrated for the first time that viral miRNA feedback regulates viral replication by suppressing the expression of RR.

Abstract
Bovine herpesvirus (BoHV) types 1 and 5 are two closely related alpha-herpesviruses of cattle with neuroinvasive potential. BoHV-5 causes non-suppurative meningoencephalitis in calve whereas encephalitis caused by BoHV-1 has been occasionally reported. As an initial step to understand the biology of both BoHV types in neural cells, undifferentiated SH-SY5Y human neuroblastoma cells were infected with BoHV-1 strains Cooper and Los Angeles (LA), BoHV-5 strain 97/613 and A663, a BoHV-5/BoHV-1 natural recombinant. Cytopathic effect (CPE) in these cells was evident earlier for BoHV-5 strain 97/613 and CPE progression was slower for BoHV-1, particularly for Cooper strain. Virus antigen was detected as early as 8 h post-infection (hpi) for all strains, with the exception of BoHV-1 Cooper for which antigen expression was detectable by 24 hpi. All strains released detectable infectious virus in the extracellular medium by 8 hpi, confirming that undifferentiated SH-SY5Y cells are fully permissive to BoHV infection. Significantly different extracellular virus titers among the different strains were detected by 24 hpi, with BoHV-5 97/613 reaching the maximal virus production. The lowest extracellular titer was recorded for BoHV-1 Cooper at all the evaluated time-points. BoHV-1 Cooper, BoHV-1 LA and BoHV-5 97/613 had a steady increase in intracellular virus production. The evaluation of lysis plaques formation revealed that BoHV-5 A663 produced the largest plaques followed by BoHV-5 97/613. Both BoHV-1 strains produced smaller plaques when compared with BoHV-5. Despite a slower replicative cycle, strain A663 is more efficient in cell to cell dissemination. Thus, it is evident that BoHV-5 strains have growth advantages in undifferentiated neural cells compared with BoHV-1. This in vitro model might be useful to analyze the neuropathogenic potential of bovine alphaherpesviruses.

Abstract
Bovine herpesvirus types 1 (BoHV-1) and 5 (BoHV-5) are two closely related alphaherpesviruses. BoHV-1 causes several syndromes in cattle, including respiratory disease and sporadic cases of encephalitis, whereas BoHV-5 is responsible for meningoencephalitis in calves. Although both viruses are neurotropic, they differ in their neuropathogenic potential. This review summarizes the findings on the specific mechanisms and pathways known to modulate the pathogenesis of BoHV-1 and BoHV-5, particularly in relation to respiratory and neurological syndromes, which characterize BoHV-1 and BoHV-5 infections, respectively.

Abstract
Bovine alphaherpesvirus types 1 (BoHV-1) and 5 (BoHV-5) are closely related alphaherpesviruses. BoHV-5 causes non-suppurative meningoencephalitis in calves. BoHV-1 is associated with several syndromes and, occasionally, can cause encephalitis. Although both viruses are neurotropic and they share similar biological properties, it is unknown why these alphaherpesviruses differ in their ability to cause neurological disease. Neural tissue samples were collected from BoHV-1- and BoHV-5-intranasally inoculated calves during acute infection, latency and reactivation and the levels of cyclins mRNA expression were analyzed by qRT-PCR. Striking differences in the levels of cyclins mRNA were particularly detected in trigeminal ganglion (TG). The expression levels of cyclins in TG during BoHV-5 latency suggest that these viruses utilize different strategies to persist in the host. It is apparent that a relationship between virus loads and cyclin mRNA levels can be established only during acute infection and other factors might be involved in the regulation of cell cycle components during BoHV latency and reactivation. Bovine alphaherpesviruses neuropathogenicity might be influenced by the differential control of cell cycle components by these herpesviruses. This is the first report on BoHV-5 modulation of cyclins expression in neural tissues from its natural host.

Abstract
Bovine herpesvirus type 1 and type 5 (BoHV-1 and BoHV-5) are two alphaherpesviruses that affect cattle with two different syndromes. While BoHV-1 mainly produces respiratory symptoms, BoHV-5 is highly neuropathogenic and responsible for meningoencephalitis in young cattle. The latency-related (LR) gene, which is not conserved between these two herpesviruses, is the only viral gene abundantly expressed in latently infected neurons. The antiapoptotic action of this gene has been demonstrated during acute infection and reactivation from latency and seems to be mainly mediated by a LR protein (ORF-2) which is truncated in amino acid 51 in the case of BoHV-5. In this work, we show that the BoHV-5 LR gene is less efficient at cell survival and apoptosis inhibition in transient as well as in established neuronal cell lines compared to its BoHV-1 homolog. We hypothesize that the BoHV-5 LR gene may have novel functions that are lacking in the BoHV-1 LR gene and that these differences may contribute to its enhanced neuropathogenesis.

Abstract
Production of antimicrobial peptides cathelicidins, interferons and cytokines is an important feature in airway epithelial host defense. The innate immune response to alpha-herpesvirus infection at the sites of primary replication has not been fully studied. Thus, the aim of this study was to determine the expression of innate immune components, cathelicidins, IFNβ, TNFα and TNF receptors (TNFRI and TNFRII) during acute infection and reactivation of bovine herpesvirus type 1 (BoHV-1) and 5 (BoHV-5) in the respiratory tract and lymphoid tissue of their natural host. We found that BoHV infection modulates mainly the expression of BMAP28, a key cathelicidin in cattle. It was downregulated by both viruses in retropharyngeal lymph nodes of acutely infected-calves, and it was accompanied by a lower expression of IFNβ, TNFα and TNFRI. BoHV-5 showed a pronounced role in the downregulation of BMAP28, even in nasal mucosa and lung. However, during reactivation, BoHV-5 upregulated both BMAP28 and IFNβ in retropharyngeal lymph nodes. Acute replication induced also TNFα mRNA and protein synthesis, and expression of TNFRI and II was positively regulated during both acute infection and reactivation, particularly in the trachea. Moreover, BMAP27 was detected during BoHV-1 reactivation suggesting a potential role at this stage. Thus, cathelicidins are implicated in alpha-herpesvirus infections of the bovine respiratory system and the response is distinct during BoHV-1 and BoHV-5 acute infection and reactivation. This demonstrates that these viruses modulate differentially the components of innate immune response, possibly influencing their pathogenesis. This study provides an initial pilot analysis of factors that might be implicated in alpha-herpesvirus infection of the bovine respiratory system.

Abstract
ABSTRACT Bovine alphaherpesviruses 1 and 5 (BoHV-1/5) are main pathogens of respiratory, reproductive and neurological diseases in cattle. The aim of this study was to investigate the frequency of neutralizing antibodies against BoHV-1/5 in serum samples and to detect viral DNA in semen of bulls from beef cattle farms located in RS. A total of 372 serum and semen sample from bulls were collected in eighteen farms. Serum samples were submitted to virus neutralization (VN) assay, while semen samples were used to detect BoHV-1 and BoHV-5 DNA by PCR. VN results showed that BoHV-1/5 antibodies were detected in bulls of 66.7% (12/18) of the farms, 295 (79.5%) BoHV positive bulls, 287 for BoHV-1 and 234 for BoHV-; at 43 vaccinated bulls 72.1% (31/43) showing serology negative. BoHV-1/5 DNA was detected in the semen of three bulls; one of the them presenting BoHV-1, one out three presenting BoHV-5 and one BoHV-1/5.co-infection All BoHV DNA positive samples came from animals presenting posthitis and other genital lesions at sampling. Results showed a high seroprevalence of BoHV-1/5 antibodies in bulls as well as strong evidence that these viruses are actively circulating in the cattle farms. A remarkable finding is that in the presence of clinically evident lesions in the genital tract, both BoHV-1 and 5 may found in semen.

Abstract
Bovine herpesvirus 5 (BoHV-5) is responsible for outbreaks of meningoencephalitis that cause important economic losses in young cattle. BoHV-5 glycoprotein D (gD5) is essential for attachment and penetration into permissive cells and targeting of host immune systems, inducing strong humoral and cellular immune responses. The aim of this study was to evaluate the vaccinal immune response of vaccines formulated with the recombinant BoHV-5 gD (rgD5) in bovines. For the experiment, 72 heifers were randomly allotted into 6 different groups with 12 animals each. Group 1: vaccine formulated using inactivated BoHV-5 (iBoHV-5) adjuvanted with ISA50V2; Group 2: iBoHV-5 associated with 100 µg of rgD5 adjuvanted with ISA50V2; Group 3: 100 µg of rgD5 adjuvanted with ISA50V2; Group 4: 100 µg of rgD5 adjuvanted with Al(OH)3; Group 5: commercial vaccine; and Group 6: control group. Two doses were administered in a 26-day interval and the third after 357 days from primo vaccination. Cattle vaccinated with the vaccines formulated with iBoHV-5 plus rgD5 showed a significant (p < 0.01) five-fold increase in total immunoglobulin G (IgG) for BoHV-5, BoHV-1, and rgD5 as compared with the commercial and control groups. Also, a significant (p < 0.05) increase in IgG1 and IgG2a levels was induced in serum for rgD5. In addition, these same vaccines showed significant (p < 0.01) four-fold higher titers of BoHV-1 and -5 neutralizing antibodies. The results demonstrated that the rgD5 conserved important epitopes that were able to stimulate bovine humoral immunity response capable of viral neutralization of BoHV-1 and -5, suggesting it as a promising vaccine antigen to be used in vaccine for BoHV-1 and -5 endemic areas.

Abstract
AIM Previous research has shown that bovine herpesvirus-1 (BHV-1) in Indonesia was closely related to subtype-1 based on glycoprotein D genes. This study aimed to analyze the genetic variability of the BHV-1 isolated from the recent case in Indonesia not only based on gD but also other genes such as gB and gM and to study the homology and similarity of the sample to other BHV-1 isolated in other countries or regions. MATERIALS AND METHODS Samples were drawn from the tracheal organ in recent field case and prepared for DNA extraction. The gB, gD, and gM were amplified using nested polymerase chain reaction (nPCR) with our specifically designed primer pair and based on the specified bands of 350 bp gB, 325 bp gD, and 734 bp gM confirmed as BHV-1. The PCR product was ligated into pGEM-T and transformed into competent Escherichia coli. The purified plasmid was subsequently sequenced. RESULTS The virus sample isolated from the recent field case of infectious bovine rhinotracheitis (IBR) from Indonesia showed variability based on the gB, gD, and gM sequences. However, all of the genes had high similarity (98-100%) to BHV-1.2. CONCLUSION The recent field case of IBR in Indonesia was similar to BHV-1.2.

Bovine herpesvirus type 5 replication and induction of apoptosis in vitro and in the trigeminal ganglion of experimentally-infected cattle. Comp Immunol Microbiol Infect Dis 2018; 57:8-14.

Abstract
Bovine herpesvirus (BoHV) types 1 and 5 are neuroinvasive. Cases of BoHV-1-induced encephalitis are not as frequent as those caused by BoHV-5. In this study, the capability of BoHV-5 to induce apoptosis in cell cultures and in the trigeminal ganglion during acute infection of experimentally-infected cattle was analyzed. Apoptotic changes in cell cultures agree with the ability of the viral strains to replicate in each cell line. Marked differences were observed between the in vitro induction of apoptosis by BoHV-1Cooper and BoHV-5 97/613 strains. Apoptotic neurons were clearly evident in the trigeminal ganglion of BoHV-1-infected calves. For BoHV-5 a fewer number of positive neurons was observed. There is an association between the magnitude of bovine herpesviruses replication and the induction of apoptosis in trigeminal ganglion. These findings suggest that the induction of apoptosis and the innate immune response orchestrate the final outcome of alpha herpesviruses infection of the bovine nervous system.

Abstract
Infectious bovine rhinotracheitis/infectious pustular vulvovaginitis is one of the high economic importance diseases of cattle and caused by bovine herpesvirus1 (BoHV1). Based on the restriction endonuclease fingerprinting of viral DNA, the BoHV1 can be divided into three subtypes viz., BoHV1.1, 1.2a, and 1.2b. Since this method requires a pure viral DNA, it is time-consuming and labour intense. In the current study, the UL0.5 gene based PCR sequencing has been used for the subtyping of BoHV1. Out of five isolates, four had BoHV1-like signatures and one isolate had BoHV1.2-like signatures. Further, these viruses phylogenetically clustered under the respective subtypes. These results indicate that the UL 0.5 gene based PCR sequencing could be used as an alternate method of subtyping of BoHV1.

Abstract
BACKGROUND The varicelloviruses comprise a genus within the alphaherpesvirus subfamily, and infect both humans and other mammals. Recently, next-generation sequencing has been used to generate genomic sequences of several members of the Varicellovirus genus. Here, currently available varicellovirus genomic sequences were used for phylogenetic, recombination, and genetic distance analysis. RESULTS A phylogenetic network including genomic sequences of individual species, was generated and suggested a potential restriction between the ungulate and non-ungulate viruses. Intraspecies genetic distances were higher in the ungulate viruses (pseudorabies virus (SuHV-1) 1.65%, bovine herpes virus type 1 (BHV-1) 0.81%, equine herpes virus type 1 (EHV-1) 0.79%, equine herpes virus type 4 (EHV-4) 0.16%) than non-ungulate viruses (feline herpes virus type 1 (FHV-1) 0.0089%, canine herpes virus type 1 (CHV-1) 0.005%, varicella-zoster virus (VZV) 0.136%). The G + C content of the ungulate viruses was also higher (SuHV-1 73.6%, BHV-1 72.6%, EHV-1 56.6%, EHV-4 50.5%) compared to the non-ungulate viruses (FHV-1 45.8%, CHV-1 31.6%, VZV 45.8%), which suggests a possible link between G + C content and intraspecies genetic diversity. Varicellovirus clade nomenclature is variable across different species, and we propose a standardization based on genomic genetic distance. A recent study reported no recombination between sequenced FHV-1 strains, however in the present study, both splitstree, bootscan, and PHI analysis indicated recombination. We also found that the recently sequenced Brazilian CHV-1 strain BTU-1 may contain a genetic signal in the UL50 gene from an unknown varicellovirus. CONCLUSION Together, the data contribute to a greater understanding of varicellovirus genomics, and we also suggest a new clade nomenclature scheme based on genetic distances.

Abstract
Bovine herpesvirus subtype 1.2b (BoHV-1.2b) is associated primarily with bovine infectious pustular vulvovaginitis. We report here the complete genomic sequence of four BoHV-1.2b isolates. The DNA sequence identity of the four genomes is 98.9 %. Differences were primarily in regions containing direct repeats, specifically gene UL36 and the terminal repeat regions immediately flanking gene BICP22. BoHV-1.2b and BoHV-1.1 genomes are similar in size (~135 kb), completely orthologous with respect to regional structure and gene location, and have a 97.5 % DNA sequence homology. The most notable difference is the structure of the DNA replication origin of the two viruses.

Abstract
Oncolytic viruses have the ability to infect tumor cells and leave healthy cells intact. In this study, bovine herpesvirus 1 (BHV1; Los Angeles, Cooper, and SV56/90 strains) and bovine herpesvirus 5 (BHV5; SV507/99 and GU9457818 strains) were used to infect two neuronal tumor cell lineages: neuro2a (mouse neuroblastoma cells) and C6 (rat glial cells). BHV1 and BHV5 strains infected both cell lines and positively correlated with viral antigen detection (p < 0.005). When neuro2a cells were infected by Los Angeles, SV507/99, and GU9457818 strains, 40 % of infected cells were under early apoptosis and necroptosis pathways. Infected C6 cells were >40 % in necroptosis phase when infected by BHV5 (GU9457818 strain). Blocking caspase activation did not interfere with cell death. However, when necroptosis was blocked, 60-80 % of both infected cells with either virus switched to early apoptosis pathway with no interference with virus replication. Moreover, reactive oxygen species production and mitochondrial membrane dysfunction were detected at high levels in both infected cell lines. In spite of apoptosis and necroptosis blockage, tumor necrosis factor alpha (TNFA) and virus transcription were positively correlated for all viral strains studied. Thus, these results contribute to the characterization of BHV1 and BHV5 as potential oncolytic viruses for non-human cells. Nonetheless, the mechanisms underlying their oncolytic activity in human cells are still to be determined.

Abstract
Canine herpesvirus is a widespread alphaherpesvirus that causes a fatal haemorrhagic disease of neonatal puppies. We have used high-throughput methods to determine the genome sequences of three viral strains (0194, V777 and V1154) isolated in the United Kingdom between 1985 and 2000. The sequences are very closely related to each other. The canine herpesvirus genome is estimated to be 125 kbp in size and consists of a unique long sequence (97.5 kbp) and a unique short sequence (7.7 kbp) that are each flanked by terminal and internal inverted repeats (38 bp and 10.0 kbp, respectively). The overall nucleotide composition is 31.6% G+C, which is the lowest among the completely sequenced alphaherpesviruses. The genome contains 76 open reading frames predicted to encode functional proteins, all of which have counterparts in other alphaherpesviruses. The availability of the sequences will facilitate future research on the diagnosis and treatment of canine herpesvirus-associated disease.

Abstract
Bovine herpesviruses 1 and 5 (BoHV-1 and BoHV-5) are economically important pathogens, associated with a variety of clinical syndromes, including respiratory and genital disease, reproductive failure and meningoencephalitis. The standard serological assay to diagnose BoHV-1 and BoHV-5 infections is the virus neutralization test (VNT), a time consuming procedure that requires manipulation of infectious virus. In the present study a highly sensitive and specific single dilution indirect ELISA was developed using recombinant glycoprotein D from BoHV-5 as antigen (rgD5ELISA). Bovine serum samples (n = 450) were screened by VNT against BoHV-5a and by rgD5ELISA. Compared with the VNT, the rgD5ELISA demonstrated accuracy of 99.8%, with 100% sensitivity, 96.7% specificity and coefficient of agreement between the tests of 0.954. The rgD5ELISA described here shows excellent agreement with the VNT and is shown to be a simple, convenient, specific and highly sensitive virus-free assay for detection of serum antibodies to BoHV-5.

Abstract
The aim of the study was to determine the epidemiological data of bovine viral diarrhea
virus (BVDV), bovine herpesvirus-1 (BHV-1), bovine herpesvirus-4 (BHV-4), bovine
herpesvirus-5 (BHV-5) and Brucella–associated cattle that were previously
reported to have abortion and infertility problems in Ankara, Corum, Kirikkale and Yozgat
provinces, Turkey. Whole blood and sera samples were obtained from 656 cattle, and
antibodies against Brucella spp. were detected in 45 (6.86%) and 41
(6.25%) animals by Rose Bengal plate and serum tube agglutination tests, respectively. The
seropositivity rates against BVDV, BHV-1 and BHV-4 were 70.89%, 41.3% and 28.78%,
respectively. RT-PCR and PCR were performed to detect RNA and DNA viruses in blood
samples, respectively. The BVDV 5′-untranslated region and BHV-1 gB gene detected in this
study were phylogenetically analyzed. The BVDV strains analyzed in this study were closely
related to those previously reported from Turkey. The nucleotide sequence from the BHV-1
strain detected in this study is the first nucleotide sequence of BHV-1 circulating in
this area of Turkey deposited in the GenBank. The presence of Brucella
spp. and prevalence of BHV-1, BHV-4 and BVDV in cattle should be further investigated
throughout these regions.

Abstract
Bovine herpesviruses 1 (BoHV-1) and 5 (BoHV-5) share high genetic and antigenic
similarities, but exhibit marked differences in tissue tropism and neurovirulence.
The amino-terminal region of glycoprotein C (gC), which is markedly different in each
of the viruses, is involved in virus binding to cellular receptors and in
interactions with the immune system. This study investigated the genetic and
antigenic differences of the 5′ region of the gC (5′ gC) gene (amino-terminal) of
South American BoHV-1 (n=19) and BoHV-5 (n=25) isolates. Sequence alignments of 374
nucleotides (104 amino acids) revealed mean similarity levels of 97.3 and 94.2% among
BoHV-1 gC (gC1), respectively, 96.8 and 95.6% among BoHV-5 gC (gC5), and 62 and 53.3%
between gC1 and gC5. Differences included the absence of 40 amino acid residues (27
encompassing predicted linear epitopes) scattered throughout 5′ gC1 compared to 5′
gC5. Virus neutralizing assays testing BoHV-1 and BoHV-5 antisera against each
isolate revealed a high degree of cross-neutralization between the viruses, yet some
isolates were neutralized at very low titers by heterologous sera, and a few BoHV-5
isolates reacted weakly with either sera. The virus neutralization differences
observed within the same viral species, and more pronounced between BoHV-1 and
BoHV-5, likely reflect sequence differences in neutralizing epitopes. These results
demonstrate that the 5′ gC region is well conserved within each viral species but is
divergent between BoHV-1 and BoHV-5, likely contributing to their biological and
antigenic differences.

Abstract
Bovine herpesvirus 5 (BoHV-5) is an important pathogen of the central nervous system and has already been described in the genital tract of cattle and in semen. This virus is responsible for sporadic epizootics of fatal meningoencephalitis of calves. The objective of the present study was the identification and characterization of BoHV-5 in semen samples from bulls for the first time in Iran. DNA was extracted from bull semen samples, and the glycoprotein D (gD) gene of BoHV-5 and also the thymidine kinase (tK) gene of bovine herpesvirus 1 (BoHV-1) were amplified by PCR assay. The results showed a high prevalence of BoHV-5 (73.2 %) and BoHV-1 (25.89 %) in Iranian bull semen samples. In addition, in order to identify and compare BoHV-5 isolated from Iranian bulls with other isolates from all over the world, the gD gene of this virus was cloned and sequenced. A BLAST search showed that the sequence of the gD gene of BoHV-5 from Iran was 99 % identical to other sequences in the GenBank database. The present study indicated that semen samples are important transmission sources of BoHV-5 virus in Iranian bulls.

Abstract
The viral envelope glycoprotein D from bovine herpesviruses 1 and 5 (BoHV-1 and -5), two important pathogens of cattle, is a major component of the virion and plays a critical role in the pathogenesis of herpesviruses. Glycoprotein D is essential for virus penetration into permissive cells and thus is a major target for virus neutralizing antibodies during infection. In view of its role in the induction of protective immunity, gD has been tested in new vaccine development strategies against both viruses. Subunit, DNA and vectored vaccine candidates have been developed using this glycoprotein as the primary antigen, demonstrating that gD has the capacity to induce robust virus neutralizing antibodies and strong cell-mediated immune responses, as well as protection from clinical symptoms, in target species. This review highlights the structural and functional characteristics of BoHV-1, BoHV-5 and where appropriate, Human herpesvirus gD, as well as its role in viral entry and interactions with host cell receptors. Furthermore, the interactions of gD with the host immune system are discussed. Finally, the application of this glycoprotein in new vaccine design is reviewed, taking its structural and functional characteristics into consideration.

Abstract
Falconid herpesvirus type 1 (FaHV-1) is the causative agent of falcon inclusion body disease, an acute, highly contagious disease of raptors. The complete nucleotide sequence of the genome of FaHV-1 has been determined using Illumina MiSeq sequencing. The genome is 204,054 nucleotides in length and has a class E organization. The genome encodes approximately 130 putative protein-coding genes, of which 70 are orthologs of conserved alphaherpesvirus and Mardivirus proteins. Three FaHV-1 genes (UL3.5, UL44.5 and CIRC) were identified that encode protein homologues unique to Mardivirus and Varicellovirus. The genome also encodes homologues to the Mardivirus genes LORF2, LORF3, LORF4, LORF5, SORF3 and SORF4. An opal mutation resulting in premature termination was identified in the FaHV-1 UL43 gene. Phylogenetically, FaHV-1 resides in a monophyletic group with the other Mardiviruses but, along with anatid herpesvirus 1, represents a more distant divergence from the rest of the Mardivirus genus.

Abstract
Glycoprotein D (gD) is essential for attachment and penetration of Bovine herpesvirus 5 (BoHV-5) into permissive cells, and is a major target of the host immune system, inducing strong humoral and cellular immune responses. The aim of this study was to evaluate in mice the immunogenicity of recombinant BoHV-5 gD (rgD5) expressed in Pichia pastoris. Vaccines formulated with rgD5 alone or adjuvanted with Montanide 50 ISA V2; Emulsigen or Emulsigen-DDA was administered intramuscularly or subcutaneously. Almost all formulations stimulated a humoral immune response after the first inoculation. The only exception was observed when the rgD5 was administered subcutaneously without adjuvant, in this case, the antibodies were observed after three doses. Higher titers of neutralizing antibodies were obtained with the three oil-based adjuvant formulations when compared to non-adjuvanted vaccine formulations. The rgD5 vaccine stimulated high mRNA expression levels of Th1 (INF-γ) and pro-inflammatory cytokines (IL-17, GM-CSF). The results demonstrated that the recombinant gD from BoHV-5 conserved important epitopes for viral neutralization from native BoHV-5 gD and was able to elicit mixed Th1/Th2 immune response in mice.

Abstract
Bovine herpesvirus type 5 (BoHV-5) and bovine herpesvirus 1 (BoHV-1) are two closely related viruses. However, BoHV-5 is responsible for fatal meningitis in calves, while BoHV-1 is associated with infectious rhinotracheitis in cattle, and the mechanism by which the two viruses cause different symptoms is not well understood. In this study, we identified 11 microRNA (miRNA) genes, encoded by the BoHV-5 genome, that were processed into 16 detectable mature miRNAs in productive infection as determined by deep sequencing. We found that 6 out of 16 miRNA genes were present as two copies in the internal repeat and terminal repeat regions, resulting in a total of 17 miRNA-encoding loci distributed in both DNA strands. Surprisingly, BoHV-5 shared only one conservative miRNA with BoHV-1, which was located upstream of the origin of replication. Furthermore, in contrast to BoHV-1, no miRNAs were detected in the unique short region and locus within or near the bovine infected-cell protein 0 and latency-related genes. Variations in both the 5′ and 3′ ends of the reference sequence were observed, resulting in more than one isoform for each miRNA. All of the 16 miRNAs were detectable by stem–loop reverse transcriptase-PCR. The miRNAs with high read numbers were subjected to Northern blot analysis, and all pre-miRNAs and one mature miRNA were detected. Collectively, the data suggest that BoHV-5 encodes a different pattern of miRNAs, which may regulate the life cycle of BoHV-5 and might account for the different pathogenesis of this virus compared with BoHV-1.

Abstract
Bovine herpesviruses 1 (BoHV-1) and 5 (BoHV-5) are closely related alphaherpesviruses of cattle. While BoHV-1 is mainly associated with respiratory/genital disease and rarely associated with neurological disease, BoHV-5 is the primary agent of meningoencephalitis in cattle. The envelope glycoprotein D of alphaherpesviruses (BoHV-1/gD1 and BoHV-5/gD5) is involved in the early steps of virus infection and may influence virus tropism and neuropathogenesis. This study performed a sequence analysis of the 3' region of gD gene (gD3') of BoHV-1 isolates recovered from respiratory/genital disease (n = 6 and reference strain Cooper) or from neurological disease (n = 7); and from seven typical neurological BoHV-5 isolates. After PCR amplification, nucleotide (nt) sequencing, and aminoacid (aa) sequence prediction; gD3' sequences were compared, identity levels were calculated, and selective pressure was analyzed. The phylogenetic reconstruction based on nt and aa sequences allowed for a clear differentiation of BoHV-1 (n = 14) and BoHV-5 (n = 7) clusters. The seven BoHV-1 isolates from neurological disease are grouped within the BoHV-1 branch. A consistent alignment of 346 nt revealed a high similarity within each viral species (gD1 = 98.3 % nt and aa; gD5 = 97.8 % nt and 85.8 % aa) and an expected lower similarity between gD1 and gD5 (73.7 and 64.1 %, nt and aa, respectively). The analysis of molecular evolution revealed an average negative selection at gD3'. Thus, the phylogeny and similarity levels allowed for differentiation of BoHV-1 and BoHV-5 species, but not further division in subspecies. Sequence analysis did not allow for the identification of genetic differences in gD3' potentially associated with the respective clinical/pathological phenotypes, yet revealed a lower level of gD3' conservation than previously reported.

Abstract
The only complete genome sequence available for bovine herpesvirus 1 (BoHV-1) is a composite sequence derived from four different BoHV-1.1 strains and one BoHV-1.2 strain. Such a chimeric genome sequence is problematic for molecular genetic studies on this virus. We report here the complete genome sequence for the BoHV-1.1 NVSL reference strain Cooper. Although similar to the published chimeric genome sequence, there are a number of nucleotide substitutions and deletions/insertions across the genome, many of which affect coding sequences.

Abstract
Background Bovine herpesvirus type 5 (BoHV-5), frequently lethal in cattle, is associated with significant agricultural economic losses due to neurological disease. Cattle and rabbits are frequently used as models to study the biology and pathogenesis of BoHV-5 infection. In particular, neural invasion and proliferation are two of the factors important in BoHV-5 infection. The present study investigated the potential of bovine Wharton’s jelly mesenchymal stromal cells (bWJ-MSCs) to differentiate into a neuronal phenotype and support robust BoHV-5 replication. Results Upon inducing differentiation within a defined neuronal specific medium, most bWJ-MSCs acquired the distinctive neuronal morphological features and stained positively for the neuronal/glial markers MAP2 (neuronal microtubule associated protein 2), N200 (neurofilament 200), NT3 (neutrophin 3), tau and GFAP (glial fibrillary acidic protein). Expression of nestin, N200, β-tubulin III (TuJI) and GFAP was further demonstrated by reverse transcriptase polymerase chain reaction (RT-PCR). Following BoHV-5 inoculation, there were low rates of cell detachment, good cell viability at 96 h post-infection (p.i.), and small vesicles developed along neuronal branches. Levels of BoHV-5 antigens and DNA were associated with the peak in viral titres at 72 h p.i. BoHV-5 glycoprotein C mRNA expression was significantly correlated with production of progeny virus at 72 h p.i. (p < 0.05). Conclusion The results demonstrated the ability of bWJ-MSCs to differentiate into a neuronal phenotype in vitro and support productive BoHV-5 replication. These findings constitute a remarkable contribution to the in vitro study of neurotropic viruses. This work may pave the way for bWJ-MSCs to be used as an alternative to animal models in the study of BoHV-5 biology.

Abstract
The Chelonid fibropapilloma-associated herpesvirus (CFPHV; ChHV5) is believed to be the causative agent of fibropapillomatosis (FP), a neoplastic disease of marine turtles. While clinical signs and pathology of FP are well known, research on ChHV5 has been impeded because no cell culture system for its propagation exists. We have cloned a BAC containing ChHV5 in pTARBAC2.1 and determined its nucleotide sequence. Accordingly, ChHV5 has a type D genome and its predominant gene order is typical for the varicellovirus genus within the alphaherpesvirinae. However, at least four genes that are atypical for an alphaherpesvirus genome were also detected, i.e. two members of the C-type lectin-like domain superfamily (F-lec1, F-lec2), an orthologue to the mouse cytomegalovirus M04 (F-M04) and a viral sialyltransferase (F-sial). Four lines of evidence suggest that these atypical genes are truly part of the ChHV5 genome: (1) the pTARBAC insertion interrupted the UL52 ORF, leaving parts of the gene to either side of the insertion and suggesting that an intact molecule had been cloned. (2) Using FP-associated UL52 (F-UL52) as an anchor and the BAC-derived sequences as a means to generate primers, overlapping PCR was performed with tumor-derived DNA as template, which confirmed the presence of the same stretch of “atypical” DNA in independent FP cases. (3) Pyrosequencing of DNA from independent tumors did not reveal previously undetected viral sequences, suggesting that no apparent loss of viral sequence had happened due to the cloning strategy. (4) The simultaneous presence of previously known ChHV5 sequences and F-sial as well as F-M04 sequences was also confirmed in geographically distinct Australian cases of FP. Finally, transcripts of F-sial and F-M04 but not transcripts of lytic viral genes were detected in tumors from Hawaiian FP-cases. Therefore, we suggest that F-sial and F-M04 may play a role in FP pathogenesis.

Abstract
A latex agglutination test (LAT) based on sensitized polystyrene beads with inactivated Bovine herpesvirus 1 (BHV-1) particles was developed to detect serum antibodies against BHV-1 and Bovine herpesvirus 5 (BHV-5). Compared with a virus neutralization test using 252 serum samples, the sensitivity and specificity were 94.7% and 97.5%, respectively. Finally, 512 clinical serum samples from 3 major cattle-breeding provinces were monitored, and the overall positive rate was 34.57% (95% confidence interval: 30.45–38.69%). The results suggest that LAT has the potential to be a rapid method for the diagnosis of BHV-1 and BHV-5 infection in cattle herds.

Abstract
We herein describe a molecular analysis based on the 3' region of the glycoprotein C gene of 45 bovine herpesvirus (BoHV) isolates from Brazil (n=41), Uruguay (n=2) and Argentina (n=2). Nucleotide (nt) sequencing and alignment of 333 nt revealed levels of similarity ranging from 99.1% to 100% among BoHV-1 sequences (n=12); 96.2-100% among BoHV-5 sequences (n=32); and 77.7-90.3% between BoHV-1 and BoHV-5 sequences. The phylogenetic tree reconstruction provided a clear distinction between BoHV-1 and BoHV-5, and BoHV-1 into subtypes BoHV-1.1 and BoHV-1.2. The isolate SV 453/93 (BoHV-1 associated with genital disease) could not be included within BoHV-1 subtypes since it presented a markedly distinct nt and amino acid (aa) deduced sequences. A transmembrane domain of 24 aa and the putative cytoplasmic tail of 8 aa were identified and mapped. These results indicate that this genome region represents a suitable target for phylogenetic subgrouping of BoHV-1 and BoHV-5 isolates and, perhaps, for understanding evolutionary relationships.
