Resumo: Antibody levels of Babesia bigemina and Babesia bovis were analysed by the indirect fluorescent antibody technique in calves of Nelore and Ibagé breeds, Nelore x Fleckvieh and Nelore x Chianina, and Nelore x Charolais cross up to weaning age. Three and 14 day-old calves of some breeds and crosses showed significant positive correlation with the immunoglobulins anti - B. bigemina and/or B. bovis of the cows. Lower levels of immunoglobulins against B. bigemina were found between 28 and 56 days of age and against B. bovis between 56 and 84 days of age. The active antibody production was observed against B. bigemina at 84 days and at 112 days of age against B. bovis. The antibody level anti B. bigemina was generally higher than anti -B. bovis and the antibody curve was more similar to Nelore breed and its calf crosses than to the lbagé breed. Although the region is considered to be enzootically stable, it was concluded that there is a critical time of low humoral resistance during which the clinical symptoms of babesiosis can occur.

No período de três a quatorze dias de vida, foi observada correlação positiva e significante entre os níveis de imunoglobulinas circulantes das vacas e os anticorpos séricos dos bezerros contra B. bigemina e/ou B. bovis, em algumas raças e cruzamentos. A média do título sorológíco dos grupos experimentais apresentou um decréscimo nos níveis de anticorpos colostrais entre 28 e 56 dias de idade contra B. bigemina e entre 56 e 84 dias anti - B. bovis. A produção ativa de anticorpos contra B. bigemina foi observada aos 84 dias e aos 112 contra B. bovis. Em geral, os níveis de anticorpos contra B. bigemina foram mais elevados que o da B. bovis e houve maior semelhança na curva de anticorpos dos bezerros da raça Nelore e seus cruzamentos que os da raça lbagé. Embora a região seja considerada área de estabilidade enzoótica, conclui-se que existe um período crítico de baixa resistência humoral, no qual podem ocorrer casos clínicos de babesiose.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMadruga, Claudio RobertoAycardi, EduardoKessler, Raul HenriqueSchenk, Maria Aparecida MoreiraFigueiredo, Geraldo Ramos deCurvo, João Baptista Esmela2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16072Pesquisa Agropecuaria Brasileira; v.19, n.9, set. 1984; 1163-1168Pesquisa Agropecuária Brasileira; v.19, n.9, set. 1984; 1163-11681678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16072/10240info:eu-repo/semantics/openAccess2014-04-16T19:30:03Zoai:ojs.seer.sct.embrapa.br:article/16072Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:30:03Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
