Dendrogram of phylogenetic relationships between four patient Streptococcus gallolyticus subsp. pasteurianus isolates, labeled F5928 to F5931. Sequences of the four isolates are compared with those of type strains (designated with a “T” and the NCBI number) and Streptococcus bovis biotype II.2 CNS isolates sequenced in a previous study (Ref 174, VAMC 3681 and VAMC 4337) (4). The bar at the top indicates a 3% difference measured horizontally. All Streptococcus gallolyticus subsp. pasteurianus isolates were identical and differed from Streptococcus gallolyticus subsp. gallolyticus by two base pairs, a T at position 182 and a C at position at position 238, as described by Beck et al. (2). WPGMA, weighted-pair group method using arithmetic averages.
