| toxocara canis | A species of parasitic nematode found in the intestine of dogs. Lesions in the brain, liver, eye, kidney, and lung are caused by migrating larvae. In humans, these larvae do not follow normal patterns and may produce visceral larva migrans (larva migrans, visceral). (12 Dec 1998) |
| Toxocara mystax | A common ascarid species of cats, but not reported from dogs; prenatal infection of kittens does not occur, infection being by infective eggs, which hatch in the intestine, releasing second-stage larvae, which then undergo migration through the heart, lung, trachea, mouth, and gut, as with Ascaris lumbricoides in man; mice and other vertebrates, and also some invertebrates (e.g., earthworms, cockroaches) may serve as transport hosts, in which the migrating larvae encyst in the tissues.
