Abstract

The prevalence of Theileria spp. infection was studied in sheep in the South Khorasan province in Iran from 2003 to 2004. A total of 840 sheep from 34 flocks were clinically examined and investigated for the presence of Theileria spp. in the appropriate blood smears and any tick species on the body of the animals. In this study, 11.9% of sheep were infected with Theileria spp., with a parasitemia of 0.02-0.1%. Differences in the infection rates were statistically significant among different areas of the South Khorasan province. The highest prevalence was found in the Ferdows area (31.4%) and the lowest rate in the Nehbandan area (0.7%). The prevalence of Theileria spp. infection in males and females and between different age groups of sheep were not statistically significant. Seasonally, the prevalence of Theileria spp. infection in sheep reached its highest level in June (26.3%), whereas it decreased in July and August. It was found that 50.5% of the animals harbored Rhipicephalus sanguineus, 48.5% harboured Hyalomma anatolicum and 0.89% harboured Hyalomma dromedari.

摘要

2003年至2004年，对伊朗霍拉桑省南部绵羊的泰勒虫属感染率进行了研究。对来自34个羊群的840只绵羊进行了临床检查，并在适当的血涂片以及动物体表的蜱虫种类中调查泰勒虫属的存在情况。在本研究中，11.9%的绵羊感染了泰勒虫属，虫血症为0.02 - 0.1%。霍拉桑省南部不同地区的感染率差异具有统计学意义。费尔多斯地区的患病率最高（31.4%），内班丹地区的患病率最低（0.7%）。绵羊的雄性和雌性以及不同年龄组之间泰勒虫属感染率无统计学差异。按季节来看，绵羊泰勒虫属感染率在6月达到最高水平（26.3%），而在7月和8月有所下降。结果发现，50.5%的动物携带血红扇头蜱，48.5%携带小亚璃眼蜱，0.89%携带单峰驼璃眼蜱。
