Little is known about tick-borne diseases in Saudi Arabia, particularly regarding the prevalence of theileriosis in small ruminants. This survey studied the potential vectors of malignant theileriosis in Saudi Arabian sheep. Blood, lymph node and tick samples were collected from animals being treated or necropsied at the Veterinary Diagnostic Laboratory in Jeddah, Makkah (western region), and Bureida, Al-Qasim (central region). Blood and lymph node smears were prepared and examined for Theileria species. Theileria hirci (=T. lestoquardi) was found in lymph node smears of one out of 36 sheep (2.8%) in Jeddah and six of 25 sheep (24%) in Bureida. The erythrocytic forms were detected in 5-8% of RBCs. Ticks were found in relatively less number of sheep in Bureida and Jeddah, 17/180 and 26/125, respectively. All Theileria-infected sheep were infested with Hyalomma impeltatum except the one that carried Hyalomma anatolicum anatolicum. This suggests that H. impeltatum is a potential vector of malignant theileriosis in Saudi Arabia. |
