The present study was conducted in the light of the fact that latent toxoplasmosis has been associated with certain neurological conditions including encephalitis as well as behavioral disturbances including physical violent actions among which is suicidal behaviors. The objectives of this study were to determine the prevalence of seropositivity of IgG and IgM of T. gondii among prisoners with physical violence and to associate toxoplasmosis with predictors including demographic variables. Study methodology involved collecting a cross sectional survey data from participants. Blood samples were collected from inmates as the study group to analyze samples for T. gondii IgG and IgM. Study sample included 302 arrested persons for physical violent actions in addition to 200 participants from normal population as a reference group. Study findings showed that the level of IgG was significantly higher in study group than control group (p = 0.003). The level of T. gondii IgM was significantly higher in control group compared with study group (p = 0.000). No significant associations were observed between either T. gondii IgG or IgM with other study variables. Taken together, the results of the present study confirmed other previous studies in which latent toxoplasmosis is significantly associated with violent behaviors. Our findings showed a significant difference in T. gondii IgG level among study group and control group. The same trend was observed for T. gondii IgM.
