西藏樟木口岸2012-2014年蜱传病原体调查分析

Analysis on risk of tick-borne pathogens at Zhangmu port in Tibet

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。

ObjectiveTo explore status of various tick- borne pathogens at Zhangmu ports, assess the risk, and providescientific evidence for tick- borne diseases surveillance and prevention.MethodsThe ticks were collected at Zhangmuports in Tibet during 2012-2014, some of the tick samples were classified and identified by PCR and moleculeepidemiological techniques.ResultsA total of 1 779 ticks were collected, 232 ticks were tested, and 3 microorganismswere found： Bartonella, Rickettsia, Borrelia burgdorferi. Among them, it was the first discovery for Bartonella in Tibet, andthis was the predominant tick-borne microorganism.ConclusionA few tick-borne pathogens exist in Tibet with lower riskof human infectioon, however we should prevent cross-border spread of tick-borne infectious diseases.
