Seroprevalence of Toxocariasis among children 5-15 years-old in Bandar Abbas, South of Iran

Introduction: Human Toxocariasis is a zoonotic helminthic infection caused bymigration of larval stage of Toxocara canis and Toxocara catti (T.canis and T.catti) thatmainly 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 Abbasand rural parts of nearby health centers. Along with Antibody detection, complete bloodcount (CBC) performed for hallmark of migratory parasites, eosinophil cells.Methods: This study was designed to detect the anti-Toxocara antibodies in children inBandar Abbas, Iran. In this study, ELISA (IBL kit), method on serum of 5-15 years oldchildren who had already been examined by physicians to record signs and symptomsrelevant to Toxocariasis was performed.Results: The frequency of anti-Toxocara antibody was 0.9%9 (6.650 cases) with nosignificant 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 ofzoonotic parasite can be halted or diminished in these conditions. Low frequency ofinfected cases and rare positive serology results, along with other studies in other tropicalregions confirm the effects of environmental conditions on parasite life cycle.
