Abstract

Background: Toxoplasmosis is one of the world's most common infections in human and other warm-blooded vertebrates and has the most extensive universal spread. The purpose of this study is determining the seroprevalence of human Toxoplasma gondii infection, in the military personnel and their families referred to Baqiyatallah hospital, 2011-2015.

Materials and Methods: In this cross-sectional study, the serum of 3370 person contain 770 men and 2600 women attending the laboratories were selected and after completing the questionnaires and also by implementing Chemiluminescence method, these serums were examined for the presence of IgM and IgG immunoglobulins of the Toxoplasma gondii.

Results: The results were analyzed using the chi-square test. They showed that there were no statistical relationships between the prevalence of IgG and gender in 2011, 2013, (P>0.05) but there were significant relationships between them in 2012, 2014 and 2015 (P<0.05), also there were no statistical relationships between the prevalence of IgM and gender in all years (P>0.05). The results showed that there were statistical relationships among IgG and age (P<0.01) but there was no statistical relationships between IgM and age in all cases (P>0.05).

Conclusion: The results showed high prevalence of Toxoplasmosis in the military personnel and their families in Baqiyatallah hospital. The prevalence of IgG was somehow in the range and positive IgG titer was somewhat higher than what was reported in other studies in the North-West of the country; this could be partly due to the sensitivity and specificity of Chemiluminescence method compared to other methods of serology in diagnosis of Toxoplasmosis.
