E-mail: stelmann.ppgctia@gmail.comThe frequency of antibodies in blood serum and cerebrospinal fluid against Toxoplasma gondii in horses with a history of ataxia from the state of São Paulo, Brazil was carried out. Modified agglutination test was used to determine antibodies against T gondii, considering as positive samples with titers >= 2. of the blood samples tested, only 8 of 23 (34.78%) were positive, while CSF samples were negative when used the same technique. According to the negative results obtained for CSF, we concluded that T gondii was not the etiological agent of the myeloencephalitis in studied horses with neurological manifestation of ataxia, while the blood serological results indicated a previously exposure to T gondii.
