Abstract

Background: Coxiella burnetii causes Q fever, a zoonotic and vector-borne disease. Ticks serve as vectors for this bacterium. This study aimed to determine the prevalence of C. burnetii infection in ticks in Shahr-e-Rey County, Tehran Province.

Methods: From December 2016 to November 2017, 179 ticks were collected on sheep at animal husbandry facilities and slaughterhouses located in Shahr-e-Rey, Tehran Province. Tick samples were morphologically identified and evaluated for the presence of the C. burnetii IS1111 gene using real-time PCR.

Results: Ticks were classified into four genera: Hyalomma (66.48%), Rhipicepalus (23.47%), Dermacentor (7.26%), and Ornithodoros (2.79%). Furthermore, 35.20% of the ticks were Hyalomma nymphs.All 77 ticks were pooled by species, and C. burnetii was found in 22.08% (n= 17). Ornithodoros lahorensis was the most prevalent tick infected with C. burnetii.

Conclusion: The distribution of C. burnetii and reports of Q fever from various regions of the country strongly suggest that the monitoring system should give this disease more attention.

伊朗德黑兰Shahr-E-Rey屠宰场和农场分离的家畜蜱中的伯氏克希菌分子检测

背景：伯氏克希菌引起Q热，是一种人畜共患和媒介传播的疾病。蜱是这种细菌的载体。本研究旨在确定德黑兰省Shahr-e-Rey县蜱感染伯纳蒂克虫的流行情况。方法：2016年12月- 2017年11月，在德黑兰省Shahr-e-Rey的畜牧设施和屠宰场采集羊身上的蜱虫179只。采用实时荧光定量PCR技术对蜱类标本进行形态学鉴定，并对其是否存在伯氏蜱IS1111基因进行鉴定。结果：蜱类可分为4属：眼蜱（66.48%）、鼻甲蜱（23.47%）、皮蜱（7.26%）和鸟蜱（2.79%）。其中，35.20%为透明体若虫。77只蜱按种汇总，其中伯氏蜱占22.08%（17只）。感染伯氏锥虫最多的是拉霍氏鸟蜱。结论：从全国各地区布氏囊胞菌的分布和Q热报告情况看，监测系统应加强对该病的重视。
