TY - CHAP M1 - Book, Section TI - Toxocariasis (Visceral and Ocular Larva Migrans) A1 - Hotez, Peter J. A2 - Kline, Mark W. Y1 - 2018 N1 - T2 - Rudolph's Pediatrics, 23e AB - Toxocariasis is caused by helminth larvae of dogs and cats that ordinarily cannot complete their life cycle in humans (Fig. 326-1). Migrating larvae of zoonotic ascarids may be associated with significant pathology by wandering through extraintestinal viscera, causing tissue necrosis and provoking eosinophilic granulomatous inflammation. The clinical syndromes of visceral larva migrans (VLM), ocular larva migrans (OLM), or covert toxocariasis are most commonly caused by larvae of the dog ascarid Toxocara canis and, less frequently, the cat ascarid Toxocara cati. Covert toxocariasis refers to infection with either T canis or T cati that results in either asymptomatic infection or infection associated only with asthma, wheezing, or other pulmonary dysfunctions due to larval lung migrations, or possibly developmental delays due to larval migrations through the brain.
