This is the first case report of Stephanurus dentatus infection of a feral pig in Korea. In late April, 2000, a weakened feral pig was caught by blow gun from a very low level mountain near the Gyeongsang National University. We autopsied the feral pig in the laboratory of veterinary anatomy at the College of Veterinary Medicine.
A total of 27 adult parasites, 11 females and 16 males, and numerous eggs were observed from the cysts formed in the perirenal tissues and ureters. The average size of males was 25.1±3.2㎜ long and of the femals was 34.2±2.9㎜. The worms were stout, the females being about 2㎜ broad, and the internal organs were partly visible through the cuticle. The shape of thin-shelled eggs found in the cysts of perirenal tissues and ureter was ellisoidal and oval, and measured 40∼65×90∼115 ㎛.
The adult parasites were found in cysts which varied from 0.6 to 4㎝ in diameter, each cyst usually containing a pair of adult worms embedded in green pus. The ureter was thickened and almost occluded, with consequent hydronephrosis.
