FIG 3.

Minimum spanning tree showing the position of the nodes representing the 27 sequence types of B. licheniformis and location of strains G-1, F1-1, and F2-1. This tree was constructed using PHYLOViZ with the sequences of six housekeeping genes (adk, ccpA, recF, rpoB, spo0A, and sucC) from all of the 27 sequence types of B. licheniformis present in the MLST database (http://www.pubmlst.org) and those from strains G-1, F1-1, and F2-1. The tree shows that strains G-1, F1-1, and F2-1 are different sequence types individually and that groups F and G fall in different clusters.
