Maximum likelihood phylogenomic tree of 131 ST796 isolates. The tree was constructed from non-recombinogenic core SNPs and branches with less than 70% bootstrap support (500 replicates) were collapsed. The VSE, vanA and vanB isolates formed distinct and robust phylogroups. The single vanA + vanB isolate clustered within the vanB phylogroup. Branch lengths are proportional to core SNP differences with the scale as indicated. The inferred occurrences of intra-hospital evolution among the vanB isolates are labelled (brackets). The phylogenomic position of the ST796 most recent common ancestor (MRCA) in the ST796 tree was identified by using Enterococcus hirae (hirae_ATCC_9790, GenBank accession no. CP003504) as an outgroup. A = Alfred Health, Melbourne; B = Auckland City Hospital; C = Austin Health, Melbourne; D = John Hunter Hospital, Newcastle; E = other Auckland hospital; F = Monash Health, Melbourne; G = Royal Adelaide Hospital
