Genome-wide phylogenetic analysis of Escherichia albertii strains and those belonging to other Escherichia species and clades. A neighbour-joining tree (in box) was constructed using the concatenated nucleotide sequences of 111 single copy genes that are fully conserved in the genomes of 34 E. albertii strains, 44 E. coli strains, 5 E. fergusonii strains, and 15 strains belonging to Escherichia cryptic clades with a low probability of recombination. An enlarged view of the E. albertii lineage is shown. The three strains fully sequenced in this study are indicated by asterisks. G1–G5 indicate five phylogroups of E. albertii.
