目的掌握宁波口岸蜱的种群特征和莱姆病病原携带情况。方法采用人工小时布旗法采蜱,用PCR法检测蜱类中携带的莱姆病DNA片段。结果采集蜱872只,隶属于1科3属3种,分别为中华硬蜱、长角血蜱、镰形扇头蜱,其中长角血蜱占97.36%,为优势种;3-9月均可捕获蜱,3-6月为高峰期,7月下旬种群数量开始急剧减少;莱姆病螺旋体DNA片段检测均呈阴性。结论查清宁波口岸蜱的种群结构,宁波口岸尚无莱姆病自然疫源地的证据。
Objective To understand the population characteristics of ticks in Ningbo Port and the pathogen of Lyme disease. Methods Ticks were collected by artificial hour cloth method, and DNA fragments of Lyme disease carried by ticks were detected by PCR. Results Totally 872 ticks were collected, belonging to 3 species, 1 family, 3 species, which were Chinese Ixodes longicornis, Sitophilus longicornis and Sickle squirrel, of which 97.36% The ticks were captured, with the peak from March to June. The number of the population started to decrease sharply in late July. The detection of Lyme disease DNA fragments was negative. Conclusion The population structure of ticks in Ningbo Ports was ascertained. There was no evidence of natural foci of Lyme disease in Ningbo Ports.
