Abstract

A cross-sectional study was carried out in four indigenous communities of Costa Rica to detect presence and prevalence of Babesia caballi and Theileria equi and to investigate factors associated with presence of these hemoparasites. General condition of horses was evaluated, and hematocrits and hemoglobin were determined from blood samples of 130 horses, which were also analyzed using blood smears, nested polymerase chain reaction PCR, and immunosorbent assay c-ELISA. The general condition of the horses in terms of their body and coat was between regular and poor, and hematocrit and hemoglobin average values 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 for B. caballi and 60 46.2% for T. equi; 10 horses 7.7% showed mixed infection, when analyzed by PCR. Using c-ELISA, it was found that 90 69.2% horses had antibodies against B. caballi and 115 88.5% against T. equi, while 81 62.3% showed mixed reactions. There were no factors associated with the presence of B. caballi and T. equi. These results contrast with results previously obtained in equines in the Central Valley of Costa Rica.
