Fig. 3

Minimum spanning tree of Multilocus sequence typing (MLST) created by BioNumerics. Each solid circle denotes one ST, and the area of the circle is proportional to the number of isolates. The lines connecting the circles indicate the relationship between different STs. Different types of lines represent a difference in one allele (solid lines), two alleles (dashed lines) and three or more alleles (dotted lines). Clonal complexes (CCs) were defined as different by one/two alleles. The coloured zones surrounding the STs indicate that they belong to the same. STs enclosed by shaded areas constitute a clonal complex (CC). Of the CRKP STs, ST11 and ST1883, ST1640, ST15, ST864 belonged to CC11, ST17 and ST278, ST1401, ST495, ST1198 belonged to CC17. All the CRAB STs belonged to CC92.
