A total of 386 ticks were processed in order to investigate the occurrence of selected tick transmitted pathogens (i.e., Theileria, Babesia, Hepatozoon and Cytauxzoon) in ixodid ticks in six provinces of Iran (East Azerbaijan, Gilan, Kermanshah, Khuzestan, Sistan & Baluchestan and Tehran). Ticks identified as Dermacentor marginatus, Hyalomma aegyptium, Hy. anatolicum, Hy. asiaticum, Hy. marginatum, Ixodes ricinus, Rhipicephalus annulatus and R. sanguineus sensu lato were collected from sheep and cattle. Conventional PCR and sequencing results revealed DNA of Theileria ovis in three R. sanguineus sensu lato pools and one D. marginatus pool from sheep in Kermanshah and East Azerbaijan, T. annulata in one Hy. asiaticum pool from cattle in Kermanshah, and He. canis in an individual female Hy. aegyptium in Kermanshah. Data herein indicate the role of R. sanguineus complex and D. marginatus in the epidemiology of ovine theileriosis in western and northwestern Iran. Potential role of Hyalomma aegyptium in the transmission of He. canis is discussed. Considering non-principled movement of livestock across the country, application of efficient acaricides is advocated prior to movement in order to reduce the risk of tick infestation and transmitted pathogens.
