This document summarizes research on the potential link between infection with the parasite Toxoplasma gondii and different classifications of schizophrenia, specifically paranoid, disorganized, and catatonic schizophrenia. The research aims to address a gap in knowledge around whether T. gondii infection is correlated with specific schizophrenia subtypes rather than schizophrenia in general. The study analyzed serum samples from 500 schizophrenia patients and 500 controls in China to look for antibodies for T. gondii. Results found higher rates of latent T. gondii infection in women and those aged 20-29 with paranoid or catatonic schizophrenia compared to controls. This suggests T. gondii may be a risk factor for some schizophrenia subtypes. Further research is
