larva migrans (visceral)
Toxocariasis is infection with worms of the genus Toxocara, a genus of nematode parasites found in dog - T.canis - and cats - T.cati. Both species can sometimes be found in man.
It occurs in two types:
- visceral larva migrans
- ocular larva migrans also referred to as retinal granuloma
The phrase larva migrans refers to the fact that the worm fails to mature in humans.
