- Toxocariasis is caused by Toxocara canis ( T. canis ) and, less frequently, Toxocara catis (T. catis), which are intestinal nematodes (roundworms) found in dogs and cats, respectively. (medscape.com)
- Because the anti-Toxocara immunoglobulin-positive population is much higher than the prevalence of clinical toxocariasis, most patients are thought to have subclinical infection. (medscape.com)
- Toxocariasis is an illness of humans caused by the dog roundworm (Toxocara canis) and, less frequently, the cat roundworm (Toxocara cati). (wikipedia.org)
- Both Toxocara canis and Toxocara cati eggs require a several week incubation period in moist, humid weather outside a host before becoming infective, so fresh eggs cannot cause toxocariasis. (wikipedia.org)
- This observation illustrates the broad spectrum of the cutaneous manifestations of toxocariasis, showing that the disease may also cause febrile exanthema. (medicaljournals.se)

- In humans, toxocariasis is considered an aberrant infection because humans are incidental hosts, as the parasites cannot successfully reach full maturity in the human body. (medscape.com)

- In ocular toxocariasis, a mobile larva can be directly observed under the retina. (medscape.com)
- Ocular larva migrans (OLM) is the third syndrome, manifesting as uveitis, endophthalmitis, visual impairment or even blindness in the affected eye. (wikipedia.org)
- Ocular larva migrans (OLM) is rare compared with VLM. (wikipedia.org)
- The clinical spectrum of the disease comprises four syndromes, namely visceral larva migrans, ocular larva migrans, and the more recently recognized "common" (in adults) and "covert" (in children) pictures. (nih.gov)
- Therapy of ocular toxocariasis is primarily based upon corticosteroids use, when visceral larva migrans and few cases of common or covert toxocariasis can be treated by anthelmintics whose the most efficient appeared to be diethylcarbamazine. (nih.gov)
- Las formas clínicas descritas son la asintomática (TA), larva migrans visceral (LMV), larva migrans ocular (LMO) y encubierta ( TE ). (bvsalud.org)
- The most frequent clinical form is asymptomatic (AT) although it may present with visceral larva migrans (VLM), ocular larva migrans (OLM) or covert (TE) involvement. (bvsalud.org)

- An elevated anti-TES-Ag IgE level indicates acute infection or progressive inflammation caused by toxocariasis. (medscape.com)
- The diagnosis of toxocariasis requires a high index of suspicion and depends on serologic testing (eg, ELISA, immunoblot). (medscape.com)
