RESUMO

This study was conducted with the purpose to evaluate the clinical, laboratory and epidemiological aspects of naturally acquired Babesia equi infection in 178 horses handled in a semi-intensive system, property of the Academia Militar das Agulhas Negras Brazilian Army, situated in the city of Resende, in the Rio de Janeiro State. 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.
