The comparison of pathogenicity in the SPF chickens challenged with avian reovirus and/or fowl adenovirus

摘要: Avian reovirus (ARV) and fowl adenovirus (FAdV) were evaluated for pathogenicity in specific pathogen free (SPF) chickens. ARV was isolated from the broilers with history of malabsorption syndrome (MAS). FAdV layer breeders inclusion body hepatitis hydropericardium syndrome. Total 6 inoculated groups including 1 un-inoculated group organized and/or by oral route. The minimal pathological lesions lower viral gene detection rates present compared to those or ARV/FAdV groups. Common gross distended intestine foamy contents there cecal among evaluation methods such as histological lesion, detection, weight serum chemistry, histopathological lesion score reliable especially liver hepatic necrosis lymphocytic infiltration. However, we did not success evaluate synergetic effect mixed infection this study. Therefore, need further study reproduce using different agent rotavirus dose virus.
