Genome-based Definition of an Inflammatory Bowel Disease-associated Adherent-Invasive Escherichia coli Pathovar

Abstract

B2 AIEC thus represent a closely related cluster of IBD-associated E. coli strains that are distinct from normal commensal isolates, and which should be considered separately from the phenotypically similar but genetically distinct non-B2 AIEC strains when considering their association with intestinal pathogenesis.
