Summary

Seroprevalence of Toxocara and Taenia solium and risk factors for infection with these parasites were explored in a long-term rural settlement in São Paulo state, Brazil. An ELISA for the detection of anti-Toxocara IgG and IgE and anti-T. solium cysticerci was standardized using Toxocara excretory-secretory antigens (TES) obtained from the cultured second-stage larvae of T. canis and by vesicular fluid antigen from Taenia crassiceps cysticerci (VF). For cysticercosis, the reactive ELISA samples were assayed by Western blot using 18 kDa and 14 kDa proteins purified from VF. Out of 182 subjects, 25 (13·7%) presented anti-Toxocara IgG and a positive correlation between total IgE and the reactive index of specific anti-TES IgE (P=0·0265) was found amongst the subjects found seropositive for anti-Toxocara IgG. In these individuals 38·0% showed ocular manifestations. The frequency of anti-T. solium cysticerci confirmed by Western blot was 0·6%. Seropositivity for Toxocara was correlated with low educational levels and the owning of dogs. Embryonated eggs of Toxocara spp. were found in 43·3% of the analysed areas.
