Clinical features
  • Member of ascarid family since adult worm has 3 lips
  • Cats are infected by Toxocara cati and Toxascaris leonina
  • Ingested eggs can hatch to release larva that cause larva migrans
  • Adult worms are not a risk to humans
  • T. leonina: little risk of clinical infection, although has been reported rarely in a human leg abscess and in children as visceral larval migrans
  • T. cati: higher risk than T. leonina of visceral larval migrans (visceral, ocular and neural) (Pritt: Creepy Dreadful Wonderful Parasites Blog - Answer to Case 538 [Accessed 15 April 2019])
