Core SNP phylogeny of K. pneumoniae ST307 isolates. The phylogenetic tree was inferred with a maximum likelihood-based approach and is based on a core SNP alignment (83 sites). The (midpoint-rooted) tree is shown with bootstrap proportions for values ≥ 50% (1000 replicates; filled circles on branches) and additional metadata. The patient associated with isolate PBIO1964 (PT06) was initially present on a submission ward for bacterial isolation but later on transferred to a different ward.
