A concomitant study was carried out, of the association of positive serology for Toxocara spp. in 90 children who played in public squares used for leisure, with the frequency with which each child used these areas, and the presence of eggs of Toxocara spp. in the sand or grass in these locations. The sand and grass of their peridomiciles and school(More)

INTRODUCTION Allergic reaction to dust mites is a relatively common condition among children, triggering cutaneous and respiratory responses that have a great impact on the health of this population. Anaphylactic hypersensitivity is characterized by an exacerbated response involving the production of regulatory cytokines responsible for stimulating the(More)
The enzyme-linked immunosorbent assay (ELISA) is the most widely used tool to detect anti-Toxocara IgG antibodies for both serodiagnostic and seroepidemiological surveys on human toxocariasis. In the last eight years a high prevalence of toxocariasis (32.2-56.0%) has been reported in children attending public health units from municipalities in the state of(More)
Geographic information system (GIS) or Health geography is a geographical identification of the spatial variation of contagion disease and zoonosis risk in certain conditions. Comparing the variation of environmental contamination of Toxocara spp. sands of lawns and public areas through the Geographic Information System. Were investigated 98% of Parana(More)

Toxoplasma gondii oocysts are an important form of contamination with a high dispersion in the environment, but their detection is still a challenge. This study evaluated the recovery of oocysts from strawberries and crisphead lettuce. Samples (250 g of strawberries or one head of lettuce) were experimentally inoculated with 10, 10(2), 10(3) and 10(4) T.(More)
Despite the high dispersion of Toxoplasma gondii oocysts in the environment, there are few studies investigating their presence in vegetables consumed by the general population. This has led us to investigate its occurrence in raw vegetables. A total of 238 samples of vegetables were collected, including crisp lettuce, regular lettuce, chicory, rocket, and(More)
