To explore the genetic diversity of avian hepatitis E virus strains, we characterized the near-complete genome of a strain detected in 2010 in Hungary, uncovering moderate genome sequence similarity with reference strains. Public health implications related to consumption of eggs or meat contaminated by avian hepatitis E virus, or to poultry handling, require thorough investigation.

Duck hepatitis A virus type 3 (DHAV-3) is a viral pathogen that causes acute, high-mortality hepatitis in ducklings, and vaccination with attenuated live vaccines is currently the main preventive measure against it. However, differentiating infected from vaccinated animals (DIVA) is crucial for clinical diagnosis and effective disease control. This study aimed to develop a rapid mismatch amplification mutation assay PCR (MAMA-PCR) diagnostic method to simultaneously detect and differentiate between wild-type and vaccine strains.

Introduction: Cormorants, as protected wild animals by the State Forestry Administration of China, have a broad distribution across China. Previous studies have shown that they can be infected with multiple viruses in the , , , and families. There is limited knowledge about the other viruses that cormorants may carry and infect.

Background And Aim: Fowl adenovirus (FAdV) is the etiological agent of inclusion body hepatitis (IBH) and hepatitis-hydropericardium syndrome (HHS) in poultry. It is also detected in chickens with runting and stunting syndrome (RSS). FAdV has been detected worldwide, and genotypes 8a, 8b, and 11 have been identified in chickens with enteric problems in Brazil.

Global public health is currently undergoing unprecedented and complex changes. The COVID-19 pandemic has exposed vulnerabilities and weaknesses of the global health system, urging nations globally to prioritize pandemic prevention and response strategies. Simultaneously, emerging infectious diseases such as mpox and avian influenza, as well as re-emerging infectious diseases including tuberculosis, AIDS, and viral hepatitis, continue to pose threats to global public health security.

Duck viral hepatitis (DVH) caused by duck hepatitis A virus (DHAV) is a highly contagious and economically important disease of ducklings worldwide. In many parts of the globe, disease outbreaks are reported in spite of vaccinations, probably due to antigenic diversity among DHAV genotypes. We previously reported the first isolation of DHAV-2 (Genotype-2) from ducklings in Tamil Nadu, India.
