This is a case report on the occurrence of inclusion body hepatitis(IBH) and infectious bursal disease(IBD) among the broilers in a local farm located in Wanju, Jeollabukdo. Mostly IBH could be caused by adenovirus if the bird's immune system was first weakened by exposure to immunosupressive agents such as infectious bursal disease virus(IBDV) and chicken anemia virus(CIAV). However IBH primary occurred before IBD in this case. And recent work has demonstrated that virulent adenovirus alone can produce the disease.
