The contribution by Brazilian researchers was emphasized, especially the staff of the Tropical Medicine Institute of São Paulo (IMT).
متن کاملHuman toxocariasis.
Parasitic nematodes of the genus Toxocara are socioeconomically important zoonotic pathogens. These parasites are usually directly transmitted to the human host via the faecal-oral route and can cause toxocariasis and associated complications, including allergic and neurological disorders. Although tens of millions of people are estimated to be exposed to or infected with Toxocara spp, global e...
متن کاملImmunodiagnosis of Human Toxocariasis
Human toxocariasis is a helminthic zoonosis caused by larval stages of Toxocara canis and, less frequently, by T. cati, the roundworms of dogs and cats, respectively. Accidentally, humans ingest embryonated eggs containing the infective larva which are released in the upper small intestine and then pass through the intestinal epithelium to reach the blood vessels, where they can migrate to the ...
متن کاملHighlights of human toxocariasis.
Human toxocariasis is a helminthozoonosis due to the migration of Toxocara species larvae through human organism. Humans become infected by ingesting either embryonated eggs from soil (geophagia, pica), dirty hands or raw vegetables, or larvae from undercooked giblets. The diagnosis relies upon sensitive immunological methods (ELISA or western-blot) which use Toxocara excretory-secretory antige...
متن کاملHuman toxocariasis in rural Brazilian Amazonia: seroprevalence, risk factors, and spatial distribution.
This population-based cross-sectional study of 403 rural settlers in Brazilian Amazonia revealed an overall rate of IgG seropositivity to Toxocara canis excretory-secretory larval antigen of 26.8% (95% confidence interval [CI], 22.5-31.4%). Multilevel logistic regression analysis identified current infection with hookworm (odds ratio [OR], 2.32; 95% CI, 1.11-4.86) and residence in the most rece...
