Seroepidemiology of chronic toxoplasmosis in soldiers of garrison in Tehran

This study investigates the prevalence of chronic toxoplasmosis in soldiers of a garrison in Tehran. The results show a high prevalence of the infection, suggesting the need for attention to transmission routes and prevention measures.

  3. Introduction Toxoplasmosis almost in immune competent humans are asymptomatic and can exist chronically in different organs in the form of cysts and happens as a result of reactivation of chronic infection. Although armed forces are generally healthy, toxoplasmosis is not infrequent in this population. For instance, the seroprevalence of toxoplasmosis in military personnel in the Czech Republic was reported as 23% and Colombian military personnel who were involved in jungle operations had 80% seroprevalence. Armed forces are expected to be exposed to transmission routes in battlefields and operation environments. Therefore, military forces could be considered as high risk for toxoplasma seropositivity. The prevalence of Toxoplasma gondii, as a protozoa with a worldwide distribution, in veterans has been poorly studied, so the aim of this study was to assess the prevalence of chronic toxoplasmosis in soldiers of garrison in Tehran

  4. Material and Methods A total of 244 soldiers blood samples of 01 garrison in Tehran were collected randomly, then specific questionnaires were filled by them. The samples tested for specific Toxoplasma gondii antibodies (IgG) by Elisa method using TOXO IgG DSI kit (Germany). A positive IgG test was interpreted as a chronic toxoplasmosis. The relationship of jobs, blood types, education, blood or organ recipient, qualification of consumption in meat, or drink water and residency of participants with the prevalence of chronic toxoplasmosis were statistically analyzed.

  5. Results • - Of 244 samples, 45(27%) were positive. • - The positive chronic toxoplasmosis was significantly higher in: • *consumption of unpasteurized milk • * undercooked meat and juicy • * soil related occupations • *(P <0.05)

  6. Table: Percentage of positive cases by type of milk and meat, and a history of occupational contact with the soil

  7. Discussion we have shown that of 244 samples, 45(27%) had chronic infection and it was confirmed by some studie. There were chronic toxoplasmosis in soldiers and like some other country the prevalence of it was high, so the infection should be considered. According to the results, how the consumption of meat, milk and lack of hygiene in contact with the soil are important ways of transmission and sould be attentioned more.

  9. What,s Known As there are poor studies about the seroepidemiology of chronic toxoplasmosis in soldiers so this study designed and tried to found, how it was and transmitted among them. What,s News The prevalence of toxoplasmosis especially chronic form was high. Therefore the infection of toxoplasmosis may be considered.
