摘要

A survey was carried in North Khorasan Province, Iran in 2010-2011, designed to identify Theileria spp. infections of both sheep and ticks. The tick species were also examined. Ninety sheep from different flocks were clinically examined, and blood samples and ixodid ticks were collected. Light microscopy of blood smears revealed Theileria spp. infection in 37 (41.1%), while 74 (82.2%) of blood samples were positive using semi-nested PCR. Theileria ovis, Theileria lestoquardi, and mixed infection were detected in 63/90 (70%), 5/90 (5.5%), and 6/90 (6.6%) of samples, respectively. Of the 434 ticks that were collected, the most prevalent species was Rhipicephalus turanicus (69.3%) followed by Hyalomma marginatum turanicum (18.4%), Dermacentor marginatus (6.4%), and Rhipicephalus bursa (5.7%). The ticks were separated into 42 tick pools, and the salivary glands were dissected out in 0.85% (w/v) saline under a stereomicroscope and examined using semi-nested PCR. Three pools of H. marginatum turanicum salivary glands were infected with T. ovis and T. lestoquardi, and one pool of R. turanicus was infected with T. ovis. Based on these results, it is concluded that the prevalence of T. ovis is higher than T. lestoquardi and that H. marginatum turanicum and R. turanicus are likely vectors of T. lestoquardi and T. ovis in this area.Digital Object Identifier http://dx.doi.org/10.1007/s11250-012-0218-x
