Abstract:

Objective To explore status of various tick-borne pathogens at Zhangmu ports, assess the risk, and provide scientific evidence for tick-borne diseases surveillance and prevention. Methods The ticks were collected at Zhangmu ports in Tibet during 2012-2014, some of the tick samples were classified and identified by PCR and molecule epidemiological techniques. Results A total of 1 779 ticks were collected, 232 ticks were tested, and 3 microorganisms were found:Bartonella, Rickettsia, Borrelia burgdorferi. Among them, it was the first discovery for Bartonella in Tibet, and this was the predominant tick-borne microorganism. Conclusion A few tick-borne pathogens exist in Tibet with lower risk of human infectioon, however we should prevent cross-border spread of tick-borne infectious diseases.

摘要：

目的 了解西藏樟木口岸蜱及蜱传病原体情况并进行风险评估，为有效地监测蜱和预防控制蜱传疾病提供科学依据。方法 于2012-2014年在西藏樟木口岸采用人工布旗法采集游离蜱，对蜱进行分类鉴定并利用实时荧光PCR鉴定病原体。结果 共采集蜱1 779只，送检232份，共检出3类病原微生物，即巴尔通体、立克次体和伯氏疏螺旋体；首次在西藏地区发现巴尔通体，是蜱传疾病的主要病原体。结论 西藏樟木口岸地区存在蜱及蜱传病原体，因此，西藏樟木地区应注意蜱传疾病的风险，防范其跨境传播。
