浙江省首次在蜱中检测到莱姆病螺旋体DNA片段

Leptospira DNA of lyme disease was first detected in tick in Zhejiang province

目的:了解蜱、鼠中自然感染莱姆病螺旋体的状况。方法:用PCR法检测鼠类脾脏和蜱类中莱姆病DNA片段。结果:在浙江省金华市金东区及丽水市青田县捕到蜱215只。分别在微小牛蜱和长角血蜱中各检到阳性1份,阳性率为0.93%。结论:初步认为浙江省存在莱姆病病原,尚需进一步调查和病原分离加以证实。

Objective：To study the infection of lyme disease in wild rodent and tick in Zhejiang province. Methods：Polymerase chain reaction was used to detect leptospira DNA of lyme disease in tick and rodent＇s spleen. Results ：The 215 tick were captured from Jindong, Jinhua city and Qingtian, Lishui city. Two specimens were positive which belonged to Ha formosensis and microplus, respectively. The positive rate was 0.93%. Conclusion： It showed preliminarily that the pathogen of lyme diseaes occurred in Zhejiang, which should be further investigated by isolating the pathogen.
