Resumo: Nine pregnant mares were orally inoculated with sporuiated Toxoplasma gondii oocysts and three other were maintained as controls. The oocysts used were obtained by infecting susceptible cats, which received viable cysts from chronic infected mice with the Toxoplasma gondii "P" strain. The clinical signs, observed in experimentally infected mares, consisted of hyperthermia, lack of appetite, prostration, diarrhea, ocular mucous discharge and nasal serous discharge. At three clays post, inoculation leocopenia was observed. Parasitemia of Toxoplasma gondii was detected from two to 47 DPI. The humoral immune response appeared at the 10° DPI and its highest average level (1:16384) occurred after the 20° DPI.

The humoral immune response appeared at the 10° DPI and its highest average level (1:16384) occurred after the 20° DPI.   Nove éguas gestantes foram inoculadas, via oral, com oocistos esporulados de T. gondii, e três outras foram mantidas como controles. Os oocistos utilizados foram obtidos de fezes de gatos experimentalmente infectados com cistos oriundos de camundongos cronicamente infectados com a "cepa P". Os sinais clínicos observados nas éguas experimentalmente infectadas foram hipertermia, perda de apetite, prostração, diarréia, secreção ocular mucosa e corrimento nasal seroso. No 3°e 18° dias após inoculação detectou-se leucopenia e aumento dos níveis séricos de aspartato aminotransferase, respectivamente. Parasitemia foi detectada entre os dias 2 e 47 após inoculação. A resposta imunitária humoral iniciou-se por volta do 10° DPI e os maiores títulos (1:16384) ocorreram após o 20° DPI.   UEL2009-01-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/422810.5433/1679-0359.1998v19n1p45Semina: Ciências Agrárias; Vol. 19 No. 1 (1998); 45-49Semina: Ciências Agrárias; v. 19 n. 1 (1998); 45-491679-03591676-546Xreponame:Semina.
