Horses are among the domestic animals that closely interact with humans and are highly parasitized by ticks, which are the primary vectors of zoonoses. As horses in Tayrona National Natural Park (PNNT) are used as a means of transporting goods, luggage and people, they are in constant contact with wild animals, workers and tourists from different countries. These factors increase the transmission risk of hemoparasites. The purpose of this study was to determine the presence of Rickettsia sp., Anaplasma sp., and Theileria sp., in horse ticks in this protected area using conventional PCR. We collected 343 ticks of genera Amblyomma, Rhipicephalus and Dermacentor. Of the 61 samples analyzed by PCR, 18 (29.5%) individuals were positive for Rickettsia sp., 15 (24.5%) for Anaplasma sp. and 4 (6.6%) for Theileria sp. This is the first report of these hemoparasite genera in ticks associated with horses in this preserved natural area, demonstrating the importance of additional studies on the presence and epidemiology of hemoparasites and their vectors in domestic and wild animals in conserved areas with a high flow of tourists.
