FIG. 3.

Genetic relationship among B. cereus group strains. 16S rRNA (A) and 23S rRNA (B) phylogenetic trees obtained by minimum evolution method demonstrate the division of the B. cereus group into subgroups. Subgroup names are marked with bold on the right side of the brackets. Bootstrap volumes are reported on the branches. Numerals indicated in the quadrant parentheses denote the bootstrap volumes for each subgroup. During calculation of consensus parsimonious trees 7615 and 219 most-parsimonious trees were obtained for 16S rRNA and 23S rRNA, respectively. The percentages of most-parsimonious trees that support each subgroup in consensus parsimonious trees are presented in round parentheses. Bars indicate the scales of genetic distances.
