We previously described a novel Borrelia species (type strain MN14-1420T) that causes LB among patients with exposures to ticks in the upper midwestern United States. Patients infected with the novel species demonstrated high levels of spirochetemia and differing clinical symptoms as compared to other Bbsl genospecies. The organism was detected from human specimens using polymerase chain reaction, microscopy, serology and culture. The taxonomic status of these novel Borrelia isolates was determined using an eight housekeeping gene (uvrA, rplB, recG, pyrG, pepX, clpX, clpA and nifS) multi-locus sequence analysis (MLSA) and comparison of 16S rRNA gene, flaB, rrf-rrl, ospC and oppA2 nucleotide sequences. Using a system threshold of 98.3% similarity for delineation of Bbsl genospecies by MLSA, we demonstrated that the Borrelia spe...
