Babesia equi is a species of hemoparasite of elevated prevalence among equids in tropical regions, being hard to control, causing important economic losses because of the long periods of convalescence, decline of performance in the affected animals, expenses with medication and workers, besides the restrictions in transit of equines, either for hippic competitions or international commerce. In the Indirect Immunofluorescence Reaction, a prevalence of 85,96% (n=153) was verified, therefore the area can be considered endemic for Babesia equi and in enzootic stability. There was no significant difference in the age or sex of the seropositive animals. Laboratory parameters like packed cell volume, red blood cell count, platelet count, global and differential white blood cell counts, dosages of seric creatinine, albumin and total plasmatic proteins, all of which led to the conclusion that in the assymptomatic carrier state there is no hematologic or seric biochemical variations that could be attributed to the protozoal Babesia equi. === Este estudo foi conduzido com o intuito de avaliar achados cl?nicos, laboratoriais e epidemiol?gicos na infec??o natural de Babesia equi em 178 eq?inos mantidos em sistema semiintensivo de cria??o, de propriedade da Academia Militar das Agulhas Negras Ex?rcito Brasileiro, situada no munic?pio de Resende, Estado do Rio de Janeiro. Babesia equi ? uma esp?cie de hemoparasita de elevada preval?ncia entre eq??deos de ?reas tropicais, sendo de dif?cil controle, causando perdas econ?micas importantes, pelos longos per?odos de convalescen?a, queda de desempenho nos animais acometidos, gastos com medicamentos e m?o de obra, al?m de impor restri??es no tr?nsito de eq?inos, seja para competi??es h?picas ou com?rcio internacional. Na Rea??o de Imunofluoresc?ncia Indireta, foi verificada uma preval?ncia de 85,96% (n=153), podendo ser a ?rea considerada end?mica para Babesia equi e em estabilidade enzo?tica, n?o sendo observadas diferen?as significativas entre sexo e idade dos animais. Par?metros laboratoriais como volume globular, hematimetria, plaquetometria, leucometrias global e espec?fica, dosagens de creatinina s?rica, albumina e prote?nas plasm?ticas totais foram conduzidos, podendo-se concluir que no estado de portador assintom?tico n?o h? varia??o hematol?gica ou de bioqu?mica s?rica que possa ser creditada ao protozo?rio Babesia equi.
