摘要
目的 了解东北3省蜱类携带病原体情况,为蜱传疾病的防控提供参考依据.方法 2012-2013年、2016年在东北11个市(县)采集蜱标本,采用聚合酶链式反应(PCR)法检测斑点热群立克次体(SFGR)和巴尔通体,采用巢式PCR法检测新埃立克体、查菲埃立克体和土拉弗朗西斯菌(土拉菌),采用实时荧光PCR法检测伯氏疏螺旋体和微小巴贝虫.结果 SFGR、查菲埃立克体、土拉菌、伯氏疏螺旋体和微小巴贝虫检出率分别为9.10%、4.10%、0.70%、14.95%和1.87%,差异有统计学意义(χ2=42.808,P<0.001),伯氏疏螺旋体和SFGR检出率较高,未检出新埃立克体和巴尔通体.不同蜱种中SFGR、伯氏疏螺旋体及微小巴贝虫的阳性率差异有统计学意义(χ2=12.291,P=0.016;χ2=23.409,P<0.001;χ2=11.592,P=0.028).结论 东北地区蜱类携带多种病原体,以伯氏疏螺旋体、SFGR感染较普遍,不同蜱种携带病原体种类有差异,提示该地区应加强蜱媒病原体监测及调查,为蜱媒传染病的预防与控制提供依据.
Abstract
Objective To investigate the pathogens carried by ticks in three northeastern provinces of China and provide reference basis for the prevention and control of tick borne diseases.Methods From 2012 to 2013 and in 2016,tick specimens were collected from 11 counties and cities of northeastern China.Spotted fever group rickettsiae(SFGR)and Bartonella by PCR were tested,Candidatus Neoehrlichia mikurensis,Ehrlichia chaffeensis,and Francisella tularensis by nested PCR,and Borrelia burgdorferi and Babesia microti by quantitative real-time PCR.Results The detection rate was 9.10%for SFGR,4.10%for E.chaffeensis,0.70%for F.tularensis,14.95%for Bor.burgdorferi,and 1.87%for Bab.microti,with a significant difference(χ2=42.808,P<0.001).Bor.burgdorferi and SFGR were most frequently detected,while Candidatus Neoehrlichia mikurensis and Bartonella were not found.There were significant differences between tick species in the positive rates of SFGR(χ2=12.291,P=0.016),Bor.burgdorferi(χ2=23.409,P<0.001),and Bab.microti(χ2=11.592,P=0.028).Conclusions Ticks carry a variety of pathogens in northeast China,in which Bor.burgdorferi and SFGR are more common,and pathogen species differ between tick species,suggesting that these areas should strengthen tick-borne pathogen surveillance to inform the prevention and control of tick-borne diseases.
