Aim: Prevalence and pathologic aspects of kidney worm infection in indigenous pigs were described after post-mortem examination.

Materials and Methods: Viscera of the pigs from the slaughter houses were collected. Kidneys, peri-renal fats, ureters, lungs, liver and mesenteric lymph nodes were examined for both gross and microscopic lesions.

Results: Of the 76 pigs 16 (21%) were infected with the worm. Adult parasites from renal pelvis, ureter, peri-renal fats and from renal cortex were recovered. Grossly, the affected kidneys were swollen, congested and marked with creamy-white necrotic foci visible from the surface. Peri-renal adipose and connective tissues were also congested and marked with necrotic foci. Histopathological studies revealed massive infiltration of the renal parenchyma mainly with eosinophils, however, some neutrophils and mononuclear cells were also detected, suggesting interstitial nephritis. In most of the cases, cross-sections of embedded parasites were observed in peri-renal tissues.

Conclusion: Swine kidney worm is a serious problem in pig that causes severe distortion of renal normal architecture.
