The evolvement of Toxoplasma gondii and Neospora caninum on etiology of clinical-neurological signs in dogs was investigated in this work. Ninety-eight urban dogs with neurologic disturbances were divided into two groups: Group I consisted of 67 dogs examined by the Animal Neurologic Service of Universidade Estadual de Londrina, between 1987 and 1990. Group II consisted of 31 dogs examined on the same University between 2000 and 2001. Dogs were serological evaluated for evidence of T. gondii or N. caninum. The serological results for T. gondii were 82,5% and 35.4% on groups I and II, respectively. Histologic lesions compatible with distemper on the two groups were observed. T. gondii cysts were observed in two dogs by histopathology and immunohistochemistry. Neosporosis was not observed in these dogs, possibly because their urban origin.Downloads
