To evaluate the prevalence of toxocariasis in children in Jaboatão dos Guararapes, Pernambuco in northeastern Brazil, 215 serum samples were examined by an enzyme-linked immunosorbent assay (ELISA) using a recombinant antigen. In the ELISA, 26 (12.1%) of 215 subjects were positive. In a dot-blot assay using 53 of 215 serum samples, the diagnostic results correlated with those obtained by the ELISA. Moreover, it has been confirmed that the recombinant antigen was highly specific for toxocariasis by ELISA using serum samples positive for antibody to . Considering the specificity of the recombinant antigen to toxocariasis, the ELISA or dot-blot assay using the recombinant antigen is recommended in tropical and sub-tropical regions where various parasitic infections are commonly endemic.
