The study was conducted to assess the prevalence of Theileria infection in tick vectors collected from healthy animals to record the natural infection level of theilerial parasite in the field condition. A total of 156 male and 110 semi-engorged female of Hyalomma anatolicum anatolicum were collected from cattle and buffaloes of two different agro climatic zones of Punjab, dissected and their salivary glands were stained with Methyl Green Pyronin (MGP) stain. The prevalence, intensity and abundance of Theileria annulata infection were higher in female ticks (15.45%, 5.08 and 32.88, respectively) than male ticks (8.97%, 1.69 and 18.86, respectively). The ticks collected from cattle had a higher prevalence, abundance and intensity (15.15%, 5.38 and 35.53, respectively) of T. annulata infection than the ticks collected from buffaloes (9.58%, 1.74 and 18.13, respectively). Hot and dry climate favored the development of T. annulata sporozoites in H. a. anatolicum ticks as the prevalence, abundance and intensity of T. annulata infection were higher in ticks collected from Western semi arid zone of Punjab as compared to those collected from the central plain zone with hot and humid climate.
本研究旨在评估从健康动物采集的蜱传媒介中泰勒虫感染的流行情况，以记录野外条件下泰勒虫寄生虫的自然感染水平。从旁遮普邦两个不同农业气候区的牛和水牛身上共采集了156只雄性和110只半饱血雌性安纳托利亚璃眼蜱，进行解剖，并将其唾液腺用甲基绿派洛宁（MGP）染色。环形泰勒虫感染的流行率、感染强度和感染丰度在雌性蜱中（分别为15.45%、5.08和32.88）高于雄性蜱（分别为8.97%、1.69和18.86）。从牛身上采集的蜱环形泰勒虫感染的流行率、感染丰度和感染强度（分别为15.15%、5.38和35.53）高于从水牛身上采集的蜱（分别为9.58%、1.74和18.13）。炎热干燥的气候有利于环形泰勒虫子孢子在安纳托利亚璃眼蜱中的发育，因为与从炎热潮湿气候的中部平原地区采集的蜱相比，从旁遮普邦西部半干旱地区采集的蜱环形泰勒虫感染的流行率、感染丰度和感染强度更高。
