ABSTRACT

This report on the prevalence of avian hepatitis E virus (avian HEV) among chicken flocks in Egypt. A total of 510 serum samples were collected from broiler breeder (n=191), layer breeder (n=235) and commercial broiler chickens (n=84) from different farm flocks (24 flocks) in Egypt. These samples were examined for the presence of avian HEV antibody using enzyme linked immuno-sorbent assay (ELISA). The results revealed that the occurrence of avian HEV was 15.7% (80/510) and 66.7% (16/24) of the examined flocks. HEV antibody prevalence increased as age dependent and most commonly occurred among broiler breeder flocks (10/24). In conclusion, the occurrence of avian HEV was confirmed for the first time among chicken flocks in Egypt.
