Toxoplasmosis is caused by the protozoan Toxoplasma gondii, a cosmopolitan zoonosis that affectsseveral warm-blooded animal species. The main transmission routes of T. gondii are fecal-oral, carnivorous andcongenital.Congenital transmission, when the parasite reaches the concept via the transplanted route, is oftenmore severe, which transmits tachyzoites to the fetus.. The present study was carried in 13 production units ofcattle in the municipalities near from Teresina. Blood collection was performed by jugular venipuncture, using a15 ml collection tubes without anticoagulant. For the identification of. anti-T. gondii used the technique ofindirect immunofluorescence (IIF) for detection of antibodies of the IgG class. The prevalence of infection by theprotozoan parasite for the samples examined was 17,44% (68/390) of seropositive animals and 82,56%(322/390) seronegative, distributed in 100% (13/13) of the herds studied. Also demonstrated in this study, theoccurrence of at least one animal tested positive for T. gondii, in each flock evaluated.(AU)
