Reclassification of Borrelia spp. Isolated in South Korea Using Multilocus Sequence Typing

: Here, we used multilocus sequence typing (MLST) to evaluate 3 intergenic genes (16S rRNA, ospA, and 5S-23S IGS) in Borrelia isolated from South Korea to analyze the relationships between host, vector, and molecular background. We identified B. afzelii, B. yangtzensis, B. garinii, and B. bavariensis. This study is the first report for the identification of B. yangtzensis using MLST in South Korea.
