Fig 5. Minimum spanning tree of the isolates of 76 S. sonnei isolates from Guizhou Province based on the Multilocus sequence typing (MLST).

Fig 5

The minimum spanning tree was constructed with the six STs of the 76 isolates from Guizhou Province using BioNumerics Software. Minimum spanning tree algorithm of BioNumerics software was used to construct a minimum spanning tree (MST) to determine phylogenetic pattern. Each circle corresponds to a sequence type. The shadow zone indicates the six STs belonging to one clonal complex. The size of the circle is proportional to the number of the isolates, and the color within the cycles represents the serotypes of the isolates. The corresponding colour, serotype, number of isolates and back ground information were shown below the minimum spanning tree.
