Divergence of Borrelia burgdorferi sensu lato spirochetes could be driven by the host: diversity of Borrelia strains isolated from ticks feeding on a single bird

The percentage of identity of housekeeping genes of SCW-30 strains to the closest alleles available in MLST database are presented in the Table 1.
SCW-41^Ta is a type strain of Borrelia americana and represents subgroup A (ATCC BAA-1877; DSM 22541).
SCW-33^b represents B. americana subgroup B.
176^c -unique allele numbers of housekeeping genes in MLST database. Strain allelic profile is a composition of 8 numbers presented in a single row. Marked in bold are values that are below or equal to a cut-off value of 0.170 determined for the MLST scheme based on eight chromosomally located housekeeping genes [26].
