Resumo: The study aimed to evaluate pathological findings, clinical signs and weight gain of naturally infected rabbits by Trypanosoma evansi. Nine male rabbits from two to six-month-old were divided into three groups (A, B, C) with three animals each. Rabbits from groups A and B were infected with T. evansi and evaluated daily through peripheral blood smears. Group C was used as control and the animals were inoculated with saline buffer only. The animals were sacrificed after 120 DPI. Irregular parasitemic peaks ranging from 0 to 5 trypomastigotes/field until 89 DPI, disappearing from circulation blood after 90 DPI. No macroscopically and microscopically alterations were observed in this study although the animals showed clinical signs as anorexia, apathy, pale mucosa and edema of the ears and eyelids when the number of protozoa increased into circulation blood. The animals infected by T. evansi showed lower body weigh gain than animals from the control group. The results showed that infection by T. evansi in rabbits is associated with systemic alterations although the animals did not die due to the consequences of the disease.

Nove coelhos, machos com idade entre dois a seis meses, foram divididos em três grupos (A, B, C) com três animais cada. Os coelhos dos grupos A e B foram inoculados com T. evansi e avaliados diariamente através de esfregaço sanguíneo periférico. O grupo C foi utilizado como controle, isto é, inoculado somente com solução fisiológica. Os animais foram acompanhados por 120 dias e posteriormente sacrificados. Observou-se durante o experimento, que a parasitemia manteve-se com picos irregulares em variações de zero a cinco tripomastigotas/campo por até 89 dias após a inoculação, desaparecendo da circulação após 90 dias. Não se observou alterações macroscópicas e microscópicas nos animais, no entanto, foram observados sinais clínicos como anorexia, apatia e mucosas pálidas, além de edema nas orelhas e pálpebras quando o número de protozoários aumentava na circulação periférica. Verificou-se que os animais parasitados por T. evansi apresentaram ganho de peso corporal inferior aos do grupo controle. Com base nos resultados, conclui-se que a infecção por T. evansi em coelhos acarreta alterações sistêmicas, embora os animais não venham a morrer em conseqüência da enfermidade.   UEL2009-10-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/357810.5433/1679-0359.2009v30n3p679Semina: Ciências Agrárias; Vol. 30 No. 3 (2009); 679-682Semina: Ciências Agrárias; v. 30 n. 3 (2009); 679-6821679-03591676-546Xreponame:Semina.
