Prosthogonimiasis is one of the most pathogenic neglected fluke infections affecting bursa Fabricii, oviduct and cloaca of poultry, reared in free ranging systems especially low intensity farming in rural areas. A farmer from Orathanadu brought a dead, ten months old hen with enlarged bursa Fabricii. A yellowish caseous mass of about 5 gm weight was present in the bursa Fabricii on the cut section. Microscopical examination of impression smears from caseous mass revealed a large number of ova of Prosthogonimus spp. Histopathologically, bursa Fabricii revealed proliferation of interfollicular fibrous tissue. Few follicles had turned into cyst like structures that contained irregular blue calcified material. Lymphoid depletion was seen in most of the follicles. This is the first report of Prosthogonimiasis in native chicken from Tamil Nadu.
