Avian hepatitis E virus is widespread among chickens in Poland and belongs to genotype 2

Big liver and spleen disease, caused by avian hepatitis E virus, has been reported in Poland, but the prevalence of the virus has not yet been investigated. In this study, 1034 serum samples from 57 breeder broiler and laying hen flocks were screened for the presence of anti-aHEV antibodies. In a ra...

Sumario:Big liver and spleen disease, caused by avian hepatitis E virus, has been reported in Poland, but the prevalence of the virus has not yet been investigated. In this study, 1034 serum samples from 57 breeder broiler and laying hen flocks were screened for the presence of anti-aHEV antibodies. In a random serology study, 56.1% of flocks were positive. Seroprevalence was higher in laying hen flocks than in broiler breeder flocks. Phylogenetic analysis of partial ORF1 and ORF2 sequences revealed that all Polish isolates belonged to genotype 2. This is the first time this genotype has been detected in Central Europe.
