OBJECTIVE: Studies have implicated Toxoplasma gondii in the etiology of mental disorders because of its neurotropic nature and its ability to modulate neurotransmitter pathways. This study aims to investigate T. gondii seroprevalence in patients with bipolar disorder and in healthy controls living in the Isparta Region of Turkey and to assess the probable relationship between T. gondii and bipolar disorder. METHODS: Fourty-eight patients with bipolar disorder and 50 healthy controls were included in the study. Sociodemographic data, possible risk factors for T. gondii infection and clinical characteristics were analyzed. Serum anti-T. gondii IgM and IgG antibody levels were measured by using chemiluminescence immunoassay method (Roche Cobas e601 analyzer, Roche Diagnostics, Mannheim, Germany). RESULTS: Anti-T. gondii IgG seropositivity rates were determined as 18.8% and 20% in the patient group and the control group, respectively. No statistically significant relationship was observed between T. gondii IgG seropositivity and bipolar disorder (p=0.876). In the study population, advanced age, low education level, living in a rural region and consumption of unwashed raw vegetable or fruit were found to be the significant risk factors for T. gondii infection (p |
