| comparative pathogenesis in specific-pathogen-free chickens of two strains of avian hepatitis e virus recovered from a chicken with hepatitis-splenomegaly syndrome and from a clinically healthy chicken. | avian hepatitis e virus (avian hev) is the primary causative agent of hepatitis-splenomegaly (hs) syndrome in chickens. recently, a genetically unique strain of avian hev, designated avian hev-va, was recovered from healthy chickens in virginia. the objective of this study was to experimentally compare the pathogenicity of the prototype strain recovered from a chicken with hs syndrome and the avian hev-va strain in specific-pathogen-free chickens. an infectious stock of the avian hev-va strain w ... | 2009 | 19570623 |
