title: Histopathological findings of the kidney Trematoda Paratanaisia spp. (Digenea: Eucotylidae) in cattle egret (Bubulcus ibis).
abstract: Paratanaisia spp. was recorded from the right kidney of a cattle egret (Bubulcus ibis) in Kafr Elsheikh governorate, Nile Delta, Egypt. The bird showed marked emaciation and dissipation. Necropsy findings revealed marked enlargement and brownish discoloration of the kidney. Microscopic examination demonstrated marked dilatation of renal tubules with hyperplasia of lining epithelium due to presence of a trematode consistent with Paratanaisia spp. Eggs of this parasite were also noticed deeply within the interstitial tissue, surrounded with mononuclear cell infiltration, thus indicating their pathogenic potential. This result is the first report of trematodes of this genus parasitizing the kidneys of cattle egrets.
