Phylogenetic tree of 50 A. baumannii strains built based on the maximum likelihood algorithm in the MEGA6 software [11] and the concatenated alleles of seven housekeeping genes with bootstrap values. The phylogenetic analysis identified ST195, ST208, ST231, ST441, ST499, and ST723 and the new sequence type ST13929. The numbers in the branches depict the sample ID of A. baumannii
