A cross-sectional study was carried out in four indigenous communities of Costa Rica to detect presence and prevalence ofBabesiacaballiandTheileria equiand to investigate factors associated with presence of these hemoparasites. General condition of horses(𝑛=285) was evaluated, and hematocrits and hemoglobin were determined from blood samples of 130 horses, which were alsoanalyzed using blood smears, nested polymerase chain reaction (PCR), and immunosorbent assay (c-ELISA). The general conditionof the horses (𝑛=285) in terms of their body and coat was between regular and poor, and hematocrit and hemoglobin averagevalues were low (19% and 10.65 g/dL, resp.). Erythrocyte inclusions were observed in 32 (24.6%) of the samples. Twenty-six samples (20.0%) gave positive results forB. caballiand 60 (46.2%) forT. equi; 10 horses (7.7%) showed mixed infection, when analyzed byPCR. Using c-ELISA, it was found that 90 (69.2%) horses had antibodies againstB. caballiand 115 (88.5%) againstT. equi,while81(62.3%) showed mixed reactions. There were no factors associated with the presence ofB. caballiandT. equi. These results contrastwith results previously obtained in equines in the Central Valley of Costa Rica |
