MRP E. coli - Shigella reference tree and a previously reported E. coli - Shigella maximum likelihood core phylogeny. Left: Aggregate MRP phylogenetic tree of 27 E. coli and Shigella strains reconstructed from 5282 Bayesian protein trees. Right: Maximum likelihood phylogenetic tree of 20 E. coli and Shigella strains reconstructed from the sequences of 1878 genes of the Escherichia core genome (taken directly from [32]) The B2 subtree, which contains a subset of bipartitions that are discordant between these two trees, is highlighted by a red box on the MRP tree.
