title: Serologic evidence of toxocariasis in northeast Brazil.
abstract: Sera from 54 Brazilian children with a history of tropical eosinophilia syndrome were screened for toxocariasis. The enzyme-linked immunosorbent assay detected 21 positive sera (40%). Many of these cases (15 of 21) were positive for Dilofilaria immitis as well. Of the six Toxocara-positive children with hypereosinophilia, two were asthmatic. Their sera were further examined by the Toxocara species-specific Ouchterlony's diffusion-in-gel test and one Toxocara canis and one T. cati infections were identified. This is the first report of serologically diagnosed toxocariasis in Brazil.
