Key result
Natural co-infection of fowl adenovirus type E-8b and avian hepatitis E virus was observed in layer breeders, with isolates showing high homology to known Chinese strains.
The study identifies and genetically characterizes a natural co-infection of FAdV type E-8b and aHEV in layer breeders in China.
Co-infection in layer breeders signals need for enhanced poultry surveillance; leaves open questions on viral interactions and disease outcomes.
• Co-infection of fowl adenovirus (FAdV) and avian hepatitis E virus (aHEV) was observed in layer breeders. • All three main genes of FAdV isolate share high homology with the E-8b type. • ORF2 from aHEV showed homology with VaHEV strain from Hy-line LCFs in China.
