Abstract：Objective To study the prevalence of Borrelia burgdorferii in ticks among Qiqian region of Inner Mongolia. Methods Free ticks were collected with the dragging method. PCR method and gene sequencing were used to detect the infection and genotyping of Borrelia burgdorferii in tick samples. Results A total of 320 ticks were collected, including 293 Ixodes persulcatus (91.56%), 22 Dermacentor silvarum (6.88%) and 5 Haemaphysalis conicinna (1.56%). The positive rate of tick-borne Borrelia burgdorferii was 26.88%, and there were three genotypes such as B.garinii, B.afzelii and B.miyamotoi. The positive rate of Ixodes persulcatus, Dermacentor silvarum, Haemaphysalis conicinna was 29.01% (85/293), 4.55% (1/22), 0 (0/5), respectively. Conclusions Ixodes persulcatus is the dominant species of ticks in Qiqian and carries various genotypes of Borrelia burgdorferii, which should be highly valued local public health authorities.
