Main Article

Figure 2

Core-genome SNP phylogeny of 12 Serratia marcescens isolates involved in outbreak in Miami, Florida, USA, 2018, depicted with KPC plasmid presence/absence matrix. Dotted circles indicate 3 major lineages involved in the outbreak. Nodes supported by bootstrap values of 100 are shown. A heat map of core genome SNP differences between strains involved in the outbreak shows genome similarity as measured by SNP distance; dark gray indicates higher similarity and lighter gray lower similarity. 1, pKP46-like; 2, pnJST258C2-like; 3, SER_520; 4, SER_508; 5, SER_502; 6, SER_500; 7, SER_514; 8, SER_501; 9, SER_518; 10, SER_505; 11, SER_522; 12, SER_523; 13, SER_525; 14, SER_517. Scale bar indicates number of differences between sequences. KPC, Klebsiella pneumoniae carbapenemase; SNP, single-nucleotide polymorphisms.
