- This study reported the clinical signs and pathological effects of Infectious bursal disease (IBD) virus in 14 week old Isa brown IBD- vaccinated pullets. Clinical signs, pathologic lesions, morbidity as well as mortality rates on the natural outbreak of infectious bursal disease (IBD) in pullets under deep litter system in a commercial poultry farm in Sokoto, Nigeria were observed and recorded. Tissues of bursa of Fabricius (BF) were collected and fixed in 10% buffered formalin and processed for histopathological examinations. During the outbreak, morbidity and mortality rate of 40% and 22% respectively were recorded and the disease course lasted for 7 days. The disease was diagnosed based on clinical signs, gross- and histo- pathologic lesions as well as agar gel immunodiffusion test (AGID). Clinical signs, gross lesions, and histopathological findings were characteristic of very virulent infectious bursal disease.
