Bursa fabricius, breeds birds, were studied histologically. It was to wall made four layers, tunica serosa, muscularis, viz. submucosa mucosa from outside inside. In both breeds, internal surface thrown into folds known plicae, lined pseudo stratified epithelium except at crypts where columnar seen. Four types follicles two epithelium, (FAE IFE), attached plicae bursa identified. Septae thickness fabricius be more. Similarily, cortex densely packed Nidhi.
