Fig. 2
Minimum spanning tree analysis of blaOXA-72-positive Acinetobacter baumannii isolates based on multilocus sequence typing (MLST) data from published literatures. The left panel (a) showed the results from ‘Bartual’ scheme, the right panel (b) showed the results from ‘Pasteur’ scheme. Each circle represents an independent sequence type (ST). The size of each circle corresponds to the number of isolates. The lines connecting the circles indicate the relationship between different STs. Black arrows are used to indicate the strains originated from China
