This study was conducted to investigate infections of camels with tick-borne diseases, namely Theileria, Babesia and Anaplasma, and Trypanosoma evansi. For this purpose, a total of 77 blood samples was collected from camels in Riyadh region, Saudi Arabia during February–April 2013. Specific PCR tests were applied for each parasite. Interestingly, no animal was found positive for the genus Theileria, T. annulata, Babesia bigemina and Anaplasma marginale. On the other hand, five camels were found positive for Trypanosoma evansi infection (6.5%). Further studies are needed to verity previous reports indicating infection of camels with Theileria spp.
