Phylogenetic diversity. Phylogenetic analysis performed using ClonalFrame based on the sequence of eight protein-coding genes (4,095 nt in total), of 161 Escherichia coli isolates from bacteremia (circles), 67 ECOR strains (open squares) and seven genome reference strains (triangles). Color of strain symbols is according to triplex-PCR grouping into major phylogenetic groups (red, B2; green, B1; yellow, D; blue, A).
