Detection of Theileria and Babesia species in ticks collected from cattle.

The present study was carried out to detect tick species that infest cattle, and Theileria and Babesia species transmitted by these ticks in Kayseri province (Turkey). A total of 300 cattle were examined for tick infestations. Of the 300 cattle, 117 (39%) were infested with ticks. A total of 1160 ticks belonging to 11 Ixodid genera were collected from the infested animals and their shelters. The most prevalent tick species was Boophilus annulatus 26.37% (306/1160) followed by Hyalomma marginatum marginatum 21.12% (245/1160) and Rhipicephalus turanicus 18.7% (217/1160). The collected ticks were separated into 43 tick pools, according to their species. These pools were examined for bovine Theileria and Babesia species (Theileria sp., Babesia sp., Theileria annulata, T. buffeli/orientalis, Babesia bigemina, B. bovis and B. divergens) by using the reverse line blotting method (RLB). Of the 43 tick pools examined, 6 (14%) were infected with B. bigemina, 4 (9.3%) with T. annulata, and 1 (2.3%) with Babesia sp., whereas 1 (2.3%) displayed mixed infection with T. annulata + B. bigemina. The sequence and phylogenetic analyses of Babesia sp., which could not be identified to the species level by RLB, were performed. In the phylogenetic tree, Babesia sp. (Kayseri 1) grouped with Babesia sp. (Kashi 2), Babesia sp. (Kashi 1), Babesia sp. (Xinjiang) and B. orientalis with 96.8-100% identity.
