Abstract
Duck hepatitis A virus type 1 (DHAV-1) is an important member of the Picornaviridae family that causes highly fatal hepatitis in ducklings. Since picornaviruses have small genomes with limited coding capacity, they must utilize host proteins for viral cap-independent translation and RNA replication. Here, we report the role of duck poly(rC)-binding protein 2 (PCBP2) in regulating the replication and translation of DHAV-1. During DHAV-1 infection, PCBP2 expression was upregulated. A biotinylated RNA pull-down assay revealed that PCBP2 positively regulates DHAV-1 translation through specific interactions with structural domains II and III of the DHAV-1 internal ribosome entry site (IRES). Further studies revealed that PCBP2 promotes DHAV-1 replication via an interaction of its KH1 domain (aa 1-92) with DHAV-1 3Dpol. Thus, our studies demonstrated the specific role of PCBP2 in regulating DHAV-1 translation and replication, revealing a novel mechanism by which host‒virus interactions regulate viral translation and replication. These findings contribute to further understanding of the pathogenesis of picornavirus infections.

Natural Infection with H5N1 Highly Pathogenic Influenza (HPAI) Virus in 5- and 10-Day-Old Commercial Pekin Ducklings ( Anas platyrhynchos domesticus). Avian Dis 2024; 68:65-71.

Abstract
Highly pathogenic avian influenza (HPAI) has resulted in catastrophic economic losses globally in poultry. This case report describes the diagnostic detection and pathology of HPAI H5N1 in 5-day-old commercial ducklings, which is an atypical age for detection of natural infection of HPAI in poultry. The pathology observed at 5 days of age was also compared to lesions observed in ducklings from the same flock evaluated at 10 days of age before depopulation. The California Animal Health and Food Safety (CAHFS) Laboratory, Tulare, received ten 5-day-old Pekin duckling (Anas platyrhynchos domesticus) carcasses for diagnostic evaluation due to mortality that started increasing at 3 days of age. The most common gross findings included bilateral pulmonary edema with congestion and enlarged, mottled livers and spleens. Microscopically, cerebral neuronophagia, pancreatic necrosis, and interstitial pneumonia with pulmonary edema were observed in the 5-day-old ducklings. Oropharyngeal and cloacal swabs were positive for avian influenza virus (AIV) by real-time reverse transcriptase PCR. The AIV was typed as HPAI, EA/AM 2.3.4.4b H5N1 goose/Guangdong clade lineage by the National Veterinary Services Laboratory. Ducks at the affected premises were depopulated 4 days after the 5-day-old ducklings were submitted to the CAHFS lab, at which time additional tissue samples were collected for comparison to 10-day-old ducklings on the same premises. Differences in microscopic lesions and AIV tissue distribution were observed between the 5-day and 10-day tissues collected. Notably, microscopic lesions were more severe in the brain and pancreas at 10 days of age. Findings in 10-day-old ducklings included cerebral lymphoplasmacytic perivascular cuffing, gliosis, neuronal degeneration, and pancreatic necrosis. AIV antigen distribution and intensity was greatest in the cerebral tissue of the brains at 10 days and in the lungs at 5 days of age. To the authors' knowledge, published studies are limited on AIV natural infection in domestic ducks less than 9 days of age.

Abstract
High pathogenicity avian influenza (HPAI) is a viral disease with devastating consequences for the poultry industry worldwide. Domestic ducks are a major source of HPAI viruses in many Eurasian countries. The infectivity and pathogenicity of HPAI viruses in ducks vary depending on host and viral factors. To assess the factors influencing the infectivity and pathogenicity of HPAI viruses in ducks, we compared the pathobiology of two HPAI viruses (H5N1 clade 2.3.2.1c and H5N6 clade 2.3.4.4e) in 5- and 25-week-old ducks. Both HPAI viruses caused mortality in a dose-dependent manner (104, 106, and 108 EID50) in young ducks. By contrast, adult ducks were infected but exhibited no mortality due to either virus. Viral excretion was higher in young ducks than in adults, regardless of the HPAI strain. These findings demonstrate the age-dependent mortality of clade 2.3.2.1c and clade 2.3.4.4e H5 HPAI viruses in ducks.

Abstract
Prior to the emergence of the Asian-origin H5 Goose/Guangdong/1/96 (Gs/GD) lineage, highly pathogenic avian influenza viruses (HPAIV) had rarely caused high mortalities in domestic geese. In 2016/2017 European epidemics, H5N8 Gs/GD clade 2.3.4.4 Group B produced an unprecedented number of outbreaks in waterfowl holdings. In this study, the pathogenesis of H5N8 HPAIV in comparison with H7N1 HPAIV, and the role of domestic geese in the epidemiology of these viruses, were evaluated. Local and commercial geese (Anser anser var. domesticus) were intranasally inoculated with 105 ELD50 of A/goose/Spain/IA17CR02699/2017 (H5N8) or A/Chicken/Italy/5093/1999 (H7N1) and monitored daily during 15 days. H5N8 was highly virulent to domestic geese, reaching 100% mortality by 10 days post-infection. Systemic microscopic necrotizing lesions associated with widespread AIV-antigen were detected by IHC techniques, the central nervous system being the most severely affected. High viral loads, measured by qRT-PCR, were present in all samples collected: oral and cloacal swabs, plasma tissues, and moderate levels in pool water. Domestic geese were also susceptible to H7N1 infection, as demonstrated by seroconversion and detection of viral RNA in tissues and plasma in some geese, but all lacked clinical signs. Viral shedding was confirmed in only some geese and was restricted to the oral route, but levels were high and still detected at the end of the study. Overall, H7N1 presents a lower lethality and shedding than H5N8 in geese; however, the viral shedding indicates that these species could play a role in the epidemiology of Gs/GD and other lineages of HPAIVs. RESEARCH HIGHLIGHTS H5N8 Gs/GD clade 2.3.4.4 Group B is highly virulent to domestic geese. The severity of H5N8 is associated with multisystemic replication. H7N1 can infect domestic geese but is avirulent to this species. Domestic geese could play a role in the epidemiology of Gs/GD HPAIVs.
