Toxocara mystax


Definition: a common ascarid species of cats, but not reported in 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 humans. Mice, other vertebrates, and also some invertebrates (earthworms, cockroaches) may serve as transport hosts, in which the migrating larvae encyst in the tissues.
