From: Stratified reconstruction of ancestral Escherichia coli diversification
Escherichia coli species phylogenetic reconstruction. Phylogenetic reconstruction using Maximum-likelihood (GTR + I + Γ, SH ≥99%) with the concatenate of 1023 genes (1,040,823 nt) present in 99.9% of sequenced E. coli strains. All concatenate with less than 95% site coverage were eliminated. The established phylogroup C could not be distinguished in phylogroup B1. Cryptic clade I was included as outgroup in the reconstruction
