Identification and pathogenicity of avian hepatitis E virus from quail.

ABSTRACT:

Background

Avian hepatitis E virus (HEV) has caused economic losses in the poultry industry and has shown a broad spectrum of infections. In 2022, a quail farm (YangLing, China) exhibited a decrease in egg production, an increase in mortality and hepatosplenomegaly. These characteristics were similar to those of avian HEV infection. To determine whether avian HEV existed on this farm and further clarify the pathogenicity caused by avian HEV under experimental conditions, the livers and spleens were collected from the diseased quails in the field for gross lesion observation and avian HEV detection; then, the pathogenicity was characterized.

Results

In the field, the results showed enlargement of the liver and spleen and hemorrhage spots on the liver, and the amplified fragme
