Abstract

Morbidity and mortality patterns as well as the gross and histological lesions which appear compatible with Infectious bursal (Gumboro) disease are described in this study. The study is based on natural outbreak of the disease in two backyard chicken flocks at the Sokoine University of Agriculture in Morogoro. Both flocks showed morbidity rate of 100% and mortality rate of 38.1-40%. Clinical signs as well as gross lesions and histopathological lesions in the bursae of Fabricius were consistently the same ln both flocks. The clinical signs and lesions observed resembled the classic features of infectious bursal disease. No attempts were made to isolate the virus responsible for this disease which only until very recently was known not to exist in Tanzania.
