Figure 5. Approximately maximum-likelihood phylogenetic trees based on recombination free core single-nucleotide polymorphisms (SNPs) inferred from ST873, ST110 and ST118 genomes and 398 representative genomes of Enterobacter cloacae complex strains in study of nosocomial outbreak involving carbapenamase-producing Enterobacter strains, Lyon, France, January 12, 2014–December 31, 2015. All nodes are supported by Shimodaira-Hasegawa test values >97%. Scale bar indicates SNPs. NA, nonattributed; ST, sequence type.
