Abstract:
Adherent enteropathogenic Escherichia coli 0119 strains had a larger lipopolysaccharide core than non-adherent strains, although the O-chains were identical. The core from the non-adherent strain 19392 contained five hexose residues in the outer region, with three L-glycero-D-manno-heptose residues and 3-deoxy-D-manno-octulosonic acid (KDO) in the inner region. The core of adherent strain JCP88 had an atypical structure consisting of six hexose residues, KDO, and equimolar amounts of L-glycero-D-manno-heptose and D-glycero-D-manno-heptose. The core of a rough JCP88 mutant resembled an incomplete 19392 core.
