浙江省建德市蜱媒传染病综合监测研究

Comprehensive surveillance of tick-borne diseases in Jiande,Zhejiang province, China

目的了解建德地区蜱媒传染病主要宿主和媒介的种群密度、季节消长、染带关系和病原体携带状况,为蜱媒传染病预防控制提供科学依据。方法采用布旗法、宿主动物体表检蜱法采集蜱,用鼠笼捕捉鼠形动物,采用PCR方法检测其蜱媒传染病感染情况。结果建德地区主要蜱种有长角血蜱、中华硬蜱和镰形扇头蜱,长角血蜱为优势种,布旗法6月蜱密度最高,体表检蜱法6月带蜱率最高。在蜱及宿主动物中检出嗜吞噬细胞无形体、巴贝西原虫、查菲埃立克体、立克次体、巴尔通体、肾综合征出血热病毒6种蜱媒传染病病原体,并存在病原体复合感染。结论建德地区蜱媒传染病的宿主和媒介广泛分布,而且携带多种病原体,需要采取措施进行防制。

Objective To study the main hosts and vectors of tick-borne diseases in Jiande, Zhejiang province, China in terms of the population seasonality and pathogen infection and to provide a scientific basis for the prevention and control of tick-borne diseases.Methods Ticks were collected with white cloth or from the host animals. Small mammals were captured using cages （please specify traps used）. The infection with tick-borne pathogens was detected by PCR.Results There wereHaemaphysalis longicornis, Ixodes sinensis, and Rhipicephalus haemaphysaloidesin Jiande, and H. longicorniswas the dominant species. The population density of ticks was the highest in June, as shown by tick collection with white cloth, while the tick-carrying rate was the highest in June, as shown by tick collection from the host animals. Anaplasma phagocytophilum, Babesia, Ehrlichia chaffeensis, Rickettsia, Bartonella, and Hantaan virus were detected in ticks and small mammals, and there were co-infections.Conclusion The hosts and vectors of tick-borne diseases are widely distributed in Jiande, and various pathogens are harbored by the tick species studies. Mitigation should be taken into consideration to prevent tick-borne diseases.
