- This research was carried out due to the little existing national information on equine hemoparasites; the objective was to determine babesiosis and trypanosomiasis prevalence in the Aburrá Valley and Rionegro Antioquia (Colombia) as well as some risk factors associated with the seropositivitie of these diseases. In 223 lots with a population of 1.008 equine venous blood sample was taken for serological diagnosis and molecular. Epidemiological information was obtained through the application of a survey addressed to persons in charge of the animals. For the statistical analysis, Chi square of independence or Fisher's Exact Test was applied when necessary. For the bivariate associations, risk estimates (OR) were calculated by explanatory variable, with their respective 95% confidence intervals (95% CI).It was found a prevalence of 11.9% for babesiosis and 1.9% for trypanosomiasis and as protection factor found the fact of going to trade fairs. Geographic location, sex and being neutered, be positive for Equine Infectious Anemia (AIE), strongyles or oxiurus was a risk factor for piroplasmosis. For Trypanosomiasis the risk factor was to be infested with ticks Dermacentor nitens or be mule. Methods of active epidemiological surveillance should be reinforced, especially in cases of continuous mobilization of equines or development of events that involve massive presence of horses.
