Fig. 3

Minimum spanning tree of the 54 S. flexneri isolates from calves with diarrhea based on multilocus sequence typing (MLST). The minimum spanning tree was constructed using the 7 identified STs obtained from the 54 isolates using BioNumerics software. Each circle corresponds to a single ST. The shaded zones in different colors correspond to different serotypes. The size of the circle is proportional to the number of isolates, and the color within the circles represents the serotype of the isolates. The corresponding color, serotype, number of isolates and background information are shown to the right of the minimum spanning tree
