Cluster analysis of partial gerA sequences from 53 B. licheniformis strains. Dendogram of partial gerA operon sequences (626 bp) in 53 B. licheniformis strains. The sequences cover parts of the last two genes (gerAB and gerAC) of the tricistronic gerA operon. The dendogram was calculated using the NJ- method with tree branch quality assessed using bootstrap values (500 replicates) as shown next to the branches. The evolutionary distances were computed using the Maximum Composite Likelihood method and are in the units of the number of base substitutions per site. MLST sequence type (ST) is indicated in brackets behind each strain and gerA cluster (1a, b, c and 2) is indicated with solid vertical lines to the right. Analyses were conducted in MEGA5.
