Abstract
Infectious bursal disease virus (IBDV) observed in a flock of 14 and 15 wk old chickens was typical of the acute symptomatic IBDV infections more common in younger birds. High flock morbidity was indicated by a marked decrease in feed consumption, although deaths were not excessive. At necropsy, affected birds had small hemorrhages in thigh muscles, creamy-yellow-colored bursae of Fabricius with prominent longitudinal striations and swollen, mottled kidneys. Histopathologic examination revealed bursal lesions typical of IBDV infection. Of 6 sera from necropsied birds, 1 was positive for antibody to IBDV in the agar-gel precipitin (AGP) test and 1 wk later all 35 samples tested were positive. Bursae contained IBDV as evidenced by precipitation with antibody to IBDV in the AGP test.
