EXPERIMENTAL INFECTION OF COLLARED PECCARY (Dicotyles tajacu angulatus) WITH SWINE KIDNEY WORM (Stephanurus dentatus)

Two captive-born juvenile collared peccaries (Dicotyles tajacu angulatus) were given 3000 infective larvae of Stephanurus dentatus per os. One peccary harbored viable S. dentatus sub-adults in the liver 50 days post-infection. The other peccary had no larvae but did have diffuse fibrotic hepatic lesions and bile duct hyperplasia 213 days post-infection; however, the lesions may have been partially due to a concurrent Ascaris suum infection. A domestic pig (Sus scrofa domesticus) infected as a control was severely but non-patently parasitized 170 days postinfection.
