Toxascaris

An ascarid nematode found primarily in the small intestine of the larger Felidae as well as dogs and cats. It differs from TOXOCARA in that the larvae do not migrate through the lungs. It does occasionally produce visceral larva migrans (LARVA MIGRANS, VISCERAL) in man, although more rarely than does Toxocara.
