Causes

See the list below:

  • Toxocara canis is the most common cause of visceral larva migrans. Mature T canis worms live in the small intestines of dogs, their natural host. Heavily infected dogs can pass millions of eggs each day in their feces. [3]

  • Toxocara cati can also cause visceral larva migrans.

  • Other etiologic agents include Baylisascaris procyonis, Capillaria hepatica, Ascaris suum, and some Ancylostoma species.
