Seroepidemiology of Toxoplasma gondii Infection in Psychiatric Inpatients and Healthy Controls in North Iran: A Case-Control Study

Objective

Gorgan, in northern Iran, is a humid region where Toxoplasma gondii is common. The association with psychiatric illness has never been examined there. We measured seroprevalence in psychiatric inpatients and matched controls, quantified it for each major DSM-5 diagnostic category, and identified local risk factors for infection.
