Natural co-infection of fowl adenovirus type E-8b and avian hepatitis E virus in parental layer breeders in Hebei, China

  • Highlights
    1. Co-infection of fowl adenovirus (FAdV) and avian hepatitis E virus (aHEV) was observed in layer breeders.
    2. All three main genes of FAdV isolate share high homology with the E-8b type.
    3. ORF2 from aHEV showed homology with VaHEV strain from Hy-line LCFs in China.
