چکیده
A total of 200 whole blood samples along with thin blood samples smears and 100 samples of ticks from 20 flocks of sheep from different localities of district Lahore with a history of tick infestation , relapse of fever and anemia were screened for the prevalence of Theileria species during spring and summer seasons in 2007. On microscopic examination 44/200 (22%) samples were positive for Theileria, while 70/200 (35%) blood samples were found positive for Theileria species by PCR, out of which 79% were positive for T. ovis and 21% for T. lestoquardi. The clinical signs were recorded in 30% (60/200) sheep. Out of total of 100 tick samples the prevalence of Hyalomma was highest (45%) followed by Rhipicephalus (41%) and Boophilus (14%).The prevalence of T. ovis was 65.8% (27/41) as compared to 66.6% (30/45) for T. lestoquardi in Rhipicephalus and Hyalomma ticks, respectively. Key word: Theileria, Pakistan, ovine.
