摘　　要：Objective:To investigate the precise species of tick vector and the Borrelia spirochete pathogen at the Heilongjiang Province international border with Russia.Methods:In dus study,ticks were collected from 12 Heilongjiang border crossings(including grasslands,shrublands,forests,and plantantions) to determine the rate and species type of spirochete-infected ticks and the most prevalent spirochete genotypes.Results:The ticks represented three genera and four species of the Ixodidae family[Ixodes persidcatus,Dermacentor silvarum,Haemapkysalis concinna and Haemaphysalis japonica].Ixodes persulcatus had the highest amount of Borrelia burgdorferi sensu lata infection of 25.6%and the most common species of Borrelia isolated from Ixodes persulcatus mas Borrelia garinii,strain PD91.Conclusions:Our results suggest that Borrelia garinii PD91- infected Ixodes persulcatus may be the principal cause of Lyme disease in the border crossing areas of Heilongjiang Province.Objective:To investigate the precise species of tick vector and the Borrelia spirochete pathogen at the Heilongjiang Province international border with Russia.Methods:In dus study,ticks were collected from 12 Heilongjiang border crossings(including grasslands,shrublands,forests,and plantantions) to determine the rate and species type of spirochete-infected ticks and the most prevalent spirochete genotypes.Results:The ticks represented three genera and four species of the Ixodidae family[Ixodes persidcatus,Dermacentor silvarum,Haemapkysalis concinna and Haemaphysalis japonica].Ixodes persulcatus had the highest amount of Borrelia burgdorferi sensu lata infection of 25.6%and the most common species of Borrelia isolated from Ixodes persulcatus mas Borrelia garinii,strain PD91.Conclusions:Our results suggest that Borrelia garinii PD91- infected Ixodes persulcatus may be the principal cause of Lyme disease in the border crossing areas of Heilongjiang Province.
