a Immuno-stained sections of lymphoid follicles in bursa of Fabricius of broiler chickens in group I showed CD 79A immune-positive in the cortex [C] and medulla [M] of the bursal follicle, bar = 50. b CD 79A immune-positive cells were depleted in the medulla (arrows). c The immune reaction increased slightly in cortex of lymphoid follicles in bursa of Fabricius of broiler chickens in group II (arrow). d In group III, immuno-stained sections of lymphoid follicles in bursa showed strong positive reaction (arrow). e The immune reaction (arrow) was moderate in group IV, bar = 20
