+, present; −, absent. The numbers in parentheses represent the percentages of nucleotide identity with respect to the original CTnBST strain, WH207.
Percent identity is based on the percent nucleotide identity outside of the 7-kb ermB region.
The % identity was based on dot blots, which require 80% identity or more to give a positive result.
