Figure 3. Bayesian phylogenetic analysis of global Klebsiella pneumoniae sequence type (ST) 307 isolates. The ST307 genomes included 88 from South Africa (this study) and 620 international isolates from 19 countries (downloaded from the US National Center for Biotechnology Information whole genome shotgun database). ST307 has 6 distinct clades, as indicated on branches. CTX-M, active on cefotaxime first isolated in Munich; KPC, Klebsiella pneumoniae carbapenemase; NDM, New Delhi metallo-β-lactamases; OXA, active on oxacillin; QRDR, quinolone resistance determinants.
