Toxocariasis is one of the most frequently reported helminth infections worldwide. Eosinophilia is a common finding of parasitic infections. This study assessed the levels of IgG antibodies specific to Toxocara spp. by ES-ELISA method in an eosinophilic (n=350) and non eosinophilic group (n=350). There were IgG antibodies specific to Toxocara spp. in 114 (32.6%) of the eosinophilic group and in 71 (20.3%) of the non-eosinophilic group (p<0.001). Toxocariasis may be an important problem in the region and should be kept in mind for patients with eosinophilia.
