Phylogenetic analysis of 452 Serratia marcescens genomes. (A) Distribution of the total pangenome after core genome multilocus sequence typing (cgMLST) analysis in core (genes present it at least 95% of the isolates; 7.6%), accessory (genes present in >2 isolates and less than in 95%; 51.6%), and unique genes (genes exclusive of a single isolate; 40.8%). (B) Phylogenetic tree inferred from cgMLST approach, including metadata of source (colors) and year (text). Strains from our collections and the reference genome for S. marcescens species (Db11 strain, assembly accession GCA_000513215.1) are highlighted in red dashed nodes. External circle highlights clusters inferred by AcCNET analysis of accessory genome.
