Introduction: Human Toxocariasis is a zoonotic helminthic infection caused by
migration of larval stage of Toxocara canis and Toxocara catti (T.canis and T.catti) that
mainly affects children. The purpose of this study was to evaluate the frequency of anti-
Toxocara antibody IgG in serums of 5-15-years-old children referred to Bandar Abbas
and rural parts of nearby health centers. Along with Antibody detection, complete blood
count (CBC) performed for hallmark of migratory parasites, eosinophil cells.
Methods: This study was designed to detect the anti-Toxocara antibodies in children in
Bandar Abbas, Iran. In this study, ELISA (IBL kit), method on serum of 5-15 years old
children who had already been examined by physicians to record signs and symptoms
relevant to Toxocariasis was performed.
Results: The frequency of anti-Toxocara antibody was 0.9%9 (6.650 cases) with no
significant gender differences. Eosinophilia (blood eosinophil count higher than 600/mm3)
was significantly related to the presence of a positive ELISA results.
Conclusion: Bandar Abbas has a warm and humid tropical climate. Transmission of
zoonotic parasite can be halted or diminished in these conditions. Low frequency of
infected cases and rare positive serology results, along with other studies in other tropical
regions confirm the effects of environmental conditions on parasite life cycle.
