Tox·as·ca·ris le·o·ni·na(tok-sas'kă-ris lē'ō-nī'nă),
An ascarid nematode of the dog that differs from Toxocara in that the larvae do not migrate through the lungs; the entire developmental cycle occurs in the gut. This parasite has been found in humans in a few instances and is a cause of visceral larva migrans in children, though less frequently implicated than is Toxocara canis.
