Figure 6From: Phylogenetic classification of Escherichia coliO157:H7 strains of human and bovine origin using a novel set of nucleotide polymorphismsNeighbor-joining tree placement of ten PFGE profiles onto corresponding polymorphism-derived genotypes. Each of the ten profiles was observed with more than one STEC O157 strain. The PFGE profile numbers match with those in Additional data file 1. Identical PFGE profiles that occurred with distantly related STEC O157 strains as determined with polymorphism-derived genotypes are highlighted in black.Back to article page
