Uncinariasis in kennelled foxhounds.

Uncinariasis was diagnosed as the cause of unthriftiness in kennelled foxhound pups. Post mortem examination of two pups revealed large numbers of Uncinaria stenocephala embedded in the mucosa of the distal small intestine. The worms were associated with blunting and thickening of villi in this region. The stereoscopic appearance of U stenocephala as seen by scanning electron microscopy is described.
