Toxoplasmosis in Nomadic Communities: A Seroepidemiological Study in Southwestern Iran

Ann Ig. 2020 Jan-Feb;32(1):50-55. doi: 10.7416/ai.2020.2329.

Abstract

Background: Toxoplasma gondii is the agent of a zoonotic protozoan infection with worldwide distribution. The rates of infection in different areas are depending on climatic conditions and also social and cultural habits of the people. This cross-sectional study aimed to find out the seroprevalence of toxoplasmosis in nomadic people in Boyer-Ahmad County, in the southwest of Iran.

Methods: Blood samples (5 mL) were collected from 1005 individuals of nomadic tribes of Boyer-Ahmad County in Kohgiluyeh and Boyer-Ahmad Province in 2016. A predesigned questionnaire, containing basic epidemiological information was filled out for each subject during the sampling. Sera were evaluated for anti-T. gondii antibodies (both IgG and IgM), using a commercial ELISA kit. Collected data were analyzed by SPSS, using descriptive statistics and Chi-square test.

Results: Out of the 1005 studied subjects, 227 (22.6%) were male and 778 (77.4%) were female. The mean age of participants was 41 years (SD: ±17). The most represented (24.4%) age class was 21-30 years and the least (1.9%) 1-10 years. Anti-T. gondii antibodies were detected in 174 (17.3%) of the cases. No statistically significant associations were found between seropositivity to T. gondii and area of residence, age, gender and educational levels of the participants.

Conclusions: Findings of this study show that the seroprevalence of toxoplasmosis among the nomads of Kohgiluyeh and Boyer-Ahmad province is alike to other communities in our country. Further study is required to elucidate the genotype of T. gondii in this community.
