From: Genetic characterization of extraintestinal Escherichia coli isolates from chicken, cow and swine
Phylogenomic analysis of E. coli isolates. Phylogenetic Supertree computed on concatenated single-copy core genes and using the Neighbor-Joining method showing the existing relationship between 19 E. coli species. CP009072 was used as the outgroup. Evolutionary analyses were conducted in TreeBest. The numbers on the branch indicate branch credibility. The branch length shows the size of the evolutionary distance which calculates in the units of the number of base substitutions per site
