T. gondii IgG antibodies were found statistically higher in 63 (53.8%) of the 117 patients with schizophrenia and in 33 (27.5%) of the 120 controls (p < 0.001). When the cases included in the schizophrenia group are examined by dividing into two sub-groups according to their suicide attempt history, the relationship between the history of suicide attempt and seroprevalence T. gondii was again found to be statistically significant (p < 0.05). In reflection of our serological findings, it was determined that the rates of T. gondii seropositivity were higher in the schizophrenia group, compared to the control group. Likewise, T. gondii IgG antibodies positivity was found to be more in schizophrenia patients with a history of suicide attempt (Table 3).
The results in Table 3 also summarized that the molecular detection ofT. gondii by PCR. The molecular positivity rate of T. gondii was higher in schizophrenia group, compared to healthy control group (p < 0.05), whereas history of suicide attempts was not statistically associated (p = 0.831) with T. gondii positivity by PCR (Table 3). This could be attributed to the fact that the T. gondii is less detected by the molecular method than the serological method. In this study, the amplified products were visualized by the standard gel electrophoresis and Figure 2 shows a sample image of electrophoresis.
