Toxoplasma gondii infection in patients with schizophrenia

Background and Objectives: Schizophrenia is a complex chronic neuropsychiatric disease of the central nervous system, believed to have multiple etiologies. Toxoplasma gondii has emerged as an interesting candidate as a possible cause of some cases of schizophrenia. As there is scarce information about the seroprevalence of T. gondii infection in psychiatric patients in Erbil; we investigated the seroprevalence of T.gondii in schizophrenic patients and compared with that obtained from control individuals in Erbil correlated with inflammatory marker C-reactive protein. Method: This case control study included 93 schizophrenic patients seeking medical advice at Hawler Psychiatric Hospital and private clinics with 93 non psychiatric control were screened for the presence of anti-toxoplasma IgG, IgM (by ELISA test) and C-reactive protein using qualitative methods. A questionnaire was used to collect socio-demographic and behavioral data among the respondents.
