Background: Toxoplasmosis in immunocompetent people is generally asympto­matic but in immunocompromised patients including HIV/AIDS, can­cer pa­tients, and organ transplant recipients, etc. it can lead to serious pathological problems. The objective of current study was to determine the seroprevalence of T. gondii IgG and IgM antibodies in HIV/AIDS patients using ELISA technique in Mazanda­ran Province, northern Iran.

Methods: Overall, 82 serum samples (61 males and 21 females) were collected from HIV/AIDS patients in Mazandaran Provinces, in 2013. Sera were surveyed employing ELISA assay. Data were analyzed using Chi-Square or Fisher exact test. In addition, before sampling a questionnaire was filled out for each subject.

Results: Overall seroprevalence of examined sera was 96.3% for IgG antibody but none of the sera shown IgM antibody against T. gondii. The seroprevalence of toxoplasmosis in males and females was 96.7% and 95.2%, respectively. An antibody titer of >1 IU/ml was considered as positive. Furthermore, none of the included variables statistically was significant.

Conclusions: Seroprevalence of chronic (latent) toxoplasmosis in HIV/AIDS patients in Mazandaran Province is high compared to toxoplasmosis in general population. Consequently, the risk of acquiring Toxoplasma encephalitis in exam­ined seropositive HIV/AIDS patients of Toxoplasma is high.
