Abstract

There are several immunosuppressive viral diseases in chickens such as avian adenovirus (AAV), chicken anemia virus (CAV), infectious bursal disease (IBD) and Marek's disease (MD). In this study, we have investigated two broiler chicken farms suffered from high mortality in Jeonbuk in July to August 2009. Clinically high fever and growth retardation were observed in the diseased chicken. In necropsy, the hemorrhages in thigh leg and thymus, hemorrhages and enlargement of liver, kidney and proventriculus, and yellowish fluid in heart were seen. Histologically, necrotic foci and basophilic intranuclear inclusion bodies of hepatocytes, hemorrhages and infiltrated lymphocytes in kidney and proventriculus were observed. By using polymerase chain reaction (PCR), the genes of avian adenovirus, CAV and ND virus were detected in specimens. We suggested that these coinfection cases with high mortality were due to primarily infection of immunosuppressive diseases such as avian adenovirus, CAV, followed by secondary infection of Newcastle disease (ND) virus.
