Abstract

The outer membrane protein and lipopolysaccharide compositions of Bacteroides fragilis strains which produced metallo-beta-lactamase were shown to be different from those of fully sensitive random clinical isolates of Bacteroides fragilis in which metallo-beta-lactamase production was not detected. This may reflect differences in the permeability barrier and provides phenotypic evidence that Bacteroides fragilis which produce metallo-beta-lactamase may belong to a separate biotype. Outer membrane profiles may provide a rapid means of identifying these problem strains.Copyright 1997 Academic Press
