Toxoplasmosis Behind Bars: One Health Approach on Serosurvey Dynamics and Associated Risk Factors for Women Inmates, Correctional Officers, and In-Prison Feral Cats.

Brazil holds the third highest general and fifth female incarcerated population worldwide. Despite the incarceration ecosystem that may favor the spreading of zoonotic diseases, particularly when unattended animals are present, no comprehensive study has focused on toxoplasmosis dynamics in such environment. Accordingly, the present study has aimed to serologically assess anti-Toxoplasma gondii (IgG) antibodies by indirect immunofluorescent antibody test in inmates, correctional officers, and feral cats at the Women's State Penitentiary of Parana, southern Brazil. In overall, 230/506 (45.5%; CI 95%: 41.2-49.8) incarcerated women, 31/91 (34.1%; 95% CI: 25.2-44.3) correctional officers, and 23/39 (59.0%; CI 95%: 43.2-72.9) cats were seropositive to anti-T. gondii antibodies. Logistic regression revealed that seropositivity likelihood increased with consumption of raw meat (p=0.040) and decreased with elementary educational level (p=0.001). No statistical difference was found comparing seropositivity between inmates and correctional officers (p=0.057). As women inmates have been considered among the most vulnerable groups in disease morbidity and mortality, seropositivity observed herein may be directly related to vulnerability and high T. gondii oocyst exposure dispersed in cat feces during incarceration.
