Objective Investigateon on vectors was carried out to identify the natural foci of Lyme disease in Nanyanggou forest area of Fangshan county of Lyuliang, Shanxi province. Methods Flagging and trapping methods were used to collect ticks, BSKⅡ media was used to isolate Lyme spirochetes from ticks. MLSA method was used to genotype the isolates. Results About 300 ticks were collected from Nanyanggou forest area, including Ixodes persulcatus, Haemaphysalis concinna, and Dermacentorm marginatus. Ixodes persulcatus was the predorminant species, which was accounted for 80% among the ticks. Two strains were isolated from I. persulcatus and H. concinna, respectively. MLSA analysis showed that 2 strains isolated from ticks belonged to Borrelia garinii. Conclusion There exists natural foci of Lyme disease in Lyuliang, Shanxi province. Detailed survey on people, vector and rodents should be carried out to provide data for prevention and control of Lyme disease in this area.
