Abstract
The ELISA test, using excretory-secretory antigen from larvae II of Toxocara canis, was applied on 1018 sera (793 from adults and 225 from pediatrics) distributed in: A) patients with an hypereosinophilia where the ethiological agent was undetermined (99); B) patients with ocular complaints compatible with an ocular toxocariasis (116); C) patients with hidatidosis (97); D) patient with other non-toxocaral helminthiasis (34); E) patients with other clinical features (468) and F) healthy donors (204).
Over 3,6 % of sera showed elevated levels of antibodies reacting with T. canis antigen. The prevalence of seropositivity was statistically higher in patients with eosinophilia (14,1%) (α < 0,001) and ocular complaints (6%) (0,025 > α > 0,01) than in the control group (1%). In the overall seropositivity from pediatrics did not differ from that of the adults.
