Emerg Infect Dis. 2016 Sep;22(9):1635-9. doi: 10.3201/eid2209.151969.


We screened 768 tick pools containing 6,962 ticks from Khammouan Province, Laos, by using quantitative real-time PCR and identified Rickettsia spp., Ehrlichia spp., and Borrelia spp. Sequencing of Rickettsia spp.-positive and Borrelia spp.-positive pools provided evidence for distinct genotypes. Our results identified bacteria with human disease potential in ticks in Laos.
