目的掌握黑龙江省东部七口岸蜱的种群特征及其感染的莱姆病病原体。方法采用人工小时布旗法采集蜱．接种于BSKⅡ培养基,分离莱姆病螺旋体。结果在七口岸共施蜱180人工小时,采集成蜱6554只,隶属于1科3属5种,其中长角血蜱为口岸蜱类新记录。主要种群为：森林革蜱(37．2％),全沟硬蜱(31．6％)．嗜群血蜱(27．6％)；不同口岸和生境蜱种群构成有所不同。从东宁、同江口岸分离到莱姆病螺旋体3株。结论基本查清黑龙江省东部七口岸蜱的种群构成,东宁、同江口岸存在莱姆病疫源地。
Objective To understand the population characteristics of ticks in seven ports of eastern Heilongjiang Province and the pathogens of Lyme disease that they infect. Methods Ticks were collected by artificial hour cloth method. Inoculated in BSKII medium, Lyme disease spirochetes were isolated. Results Totally 180 ticks were collected in seven ports, 6554 ticks were collected, which belonged to 5 species of 3 genera in 1 family. Among them, P. longicornis was a new record of port ticks. The main populations were: forest ticks (37.2%), Ixodes ixodes (31.6%). Hemiphilus group (27.6%); different port and habitat tick population composition is different. Three strains of Lyme disease were isolated from Dongning and Tongjiang ports. Conclusions The population structure of ticks in the seven ports of eastern China is basically ascertained. There are Lyme disease sources in Dongning and Tongjiang ports.
