Assigning Escherichia coli strains to phylogenetic groups: multi-locus sequence typing versus the PCR triplex method.

Abstract excerpt

It is well recognized that Escherichia coli consists of a number of distinct phylo-groups and that strains of the different phylo-groups vary in their ecological niches, life-history characteristics and propensity to cause disease. Consequently, much can be learnt by assigning a strain of E. coli to one of the recognized phylo-groups. A triplex PCR-based method that enables strains of E. coli to be assigned to a...
