ABSTRACT Orientations of the seven invertible polysaccharide biosynthesis locus promoters of B acteroides fragilis were determined from bacteria grown in vitro , from feces of monoassociated and complex colonized mice, and from B. fragilis -induced murine abscesses. Bacteria grown in vivo have greater variability in orientation of polysaccharide locus promoters than culture-grown organisms.
