Abstract: In order to systematically understand the tick-borne pathogens in the Tumen River Basin and to investigate the tick flora, the molecular epidemiology of tick-borne pathogens of Haemaph ysalis and Dermacentor as wellas the tick flora in the Tumen River Basin were investigated in the experiment. Dermacentor siluarum, Haemaphysalis japonica, Haemaphysalis concinna were collcted at 5 sampling points in 3 cities and counties in the Tumen River basin. Tickborne bacteria were investigated using high-throughput sequencing technology,and 147 ticks were analysed by second-generation sequencing of the V3-V4 variable region of the 16S gene of tick-borne bacteria. PCR was performed on 442 ticks carrying spotted fever groups Rickettsia , Anaplasma and Babesia. The results of the study showed that analyses of high-throughput sequencing results revealed the presence of at least two tick-borne pathogens and six potentially pathogenic genera with some pathogenic strains within the genus. There were differences in microflora carried by ticks of different genera and sexes in three cities and counties. One type of Rickettsia was detected in ticks in the region: Rickettsia raoultti;One type of Anaplasma : Anaplasma capra ; One species of Babesia : Babesia caballi. The obtained results provide basic data for tick borne pathogens and microbial communities in the region, and provide data support for the prevention and control of ticks and tick borne diseases.
