UPGMA (unweighted pair group method with arithmetic mean) dendrogram based on the catagorical coefficient applied to the allele IDs. All isolates with at least six loci amplified were included. The dendrogram was generated by BioNumerics 7 software. The ST numbers assigned for each isolate were generated by the Pasteur MLST scheme (http://pubmlst.org/abaumannii/). The tree is a rooted based on the nucleotide sequence of the six and seven housekeeping genes. The analysis was based on data sets that include all STs in the Pasteur MLST databases. The first clade consists of ST195, 208, 218 and 286; the second clade of ST231; the third clade of ST499; the fourth clade of ST 557; the fifth clade of ST222. The sixth and seventh clades have two nontypeable isolates due to low quality sequencing trace files
