摘要/Abstract

摘要： 目的了解内蒙古自治区（内蒙古）中西部口岸地区蜱类分布及其病原体携带情况。方法 2020年4－7月采集内蒙古策克、甘其毛都、满都拉及珠恩嘎达布其口岸地区的蜱类并对其进行种类鉴定，运用反转录PCR和普通PCR检测蜱类样本中贝氏柯克斯体、埃立克体、斑点热群立克次体、伯氏疏螺旋体、森林脑炎病毒、嗜吞噬细胞无形体和新型布尼亚病毒的携带情况。采用χ²检验分析比较不同地区蜱携带病原体情况。结果共鉴定出4种共586只寄生蜱，其中满都拉和珠恩嘎达布其口岸的优势蜱种为草原革蜱，分别占93.62%和100%；策克和甘其毛都口岸地区的优势蜱种为亚洲璃眼蜱，分别占99.17%和100%。经实验检测发现118只蜱携带贝氏柯克斯体，207只蜱携带斑点热群立克次体，21只蜱携带嗜吞噬细胞无形体，16只蜱携带埃立克体，1只蜱携带新型布尼亚病毒，80只蜱存在多重感染。结论内蒙古中西部口岸地处中蒙边境，该地区蜱携带病原体情况复杂，需进一步加强蜱传疾病监测和防控工作。

Abstract: Objective To investigate the distribution of ticks and tick-borne pathogens in the central and western ports areas of the Inner Mongolia Autonomous Region (Inner Mongolia), China. Methods From April to July 2020, ticks at Ceke, Ganqimaodu, Mandula and Zhuengadabuqi ports of Inner Mongolia were collected and identified. Reverse transcription polymerase chain reaction (RT-PCR) and PCR were used to detect the Coxiella burnetii, Ehrlichia, spotted fever group Rickettsiae, Borrelia burgdorferi, tick-borne encephalitis virus, Anaplasma phagocytophilum, and severe fever with thrombocytopenia syndrome bunyavirus (SFTSV) in tick samples. The Chi-square test was used to analyze tick-borne pathogens in different regions. Results A total of 586 parasitic ticks from four species were identified. The dominant tick species were Dermacentor nuttalli at Mandula port (93.62%) and Zhuengadabuqi port (100%), and Hyalomma asiaticum at Ceke port (99.17%) and Ganqimaodu port (100%). The PCR results showed that C. burnetii was carried in 118 ticks, spotted fever group Rickettsiae in 207 ticks, A. phagocytophilum in 21 ticks, Ehrlichia in 16 ticks, SFTSV in 1 tick, and multiple pathogens in 80 ticks. Conclusion The central and western ports of Inner Mongolia are located in the border regions between China and Mongolia, where the tick-borne pathogens are complex. It is necessary to further strengthen tick-borne disease surveillance and prevention in this region.
