Adherence of Bacteroides fragilis in vivo.
The ability of the encapsulated species Bacteroides fragilis to adhere to rat peritoneal mesothelium was compared to the adherence of unecapsulated strains of Bacteroides (B. distasonis, B. vulgatus, B. thetaiotaomicron, B. ovatus, and B. "other"). Adherence was assayed by attaching plexiglas plates containing 8-mm holes to the peritoneal mesothelium of anesthetized rats. Cell suspension (0.25 ...
متن کاملPathogenicity of the Bacteroides fragilis group.
The Bacteroides fragilis group is one of the most important pathogens in polymicrobial infections. The distribution of the different members of the B. fragilis group in clinical infections varies. Bacteroides fragilis accounts for 63 percent of all the group isolates, Bacteroides thetaiotaomicron for 14 percent, Bacteroides vulgatus and Bacteroides ovatus for seven percent each, Bacteroides dis...
متن کاملSuperoxide dismutase in Bacteroides fragilis and related Bacteroides species.
Superoxide dismutase (SOD) activity was demonstrated in cell-free extracts of Bacteroides fragilis, Bacteroides vulgatus, Bacteroides distasonis, Bacteroides ovatus, and Bacteroides thetaiotaomicron. The strains were grown under anaerobic conditions in Trypticase soy broth, and the specific activity of SOD in the extracts was, in most strains, higher than in cell-free extracts of Escherichia co...
متن کاملPost-antibiotic effect in Bacteroides fragilis group.
Post-antibiotic effect (PAE) is the transient suppression of bacterial growth after brief antimicrobial exposure. While numerous reports have described PAE with aerobic and facultative microorganisms, virtually no studies have been conducted with anaerobic isolates. Intraabdominal isolates of the Bacteroides fragilis group were exposed for one hour to antibiotic (cefoxitin, cefotetan, and imipe...
متن کاملDisk diffusion susceptibility testing of the Bacteroides fragilis group.
The susceptibilities of 225 isolates of the Bacteroides fragilis group to six antibiotics were determined by a new disk diffusion test in Wilkins-Chalgren agar and by the standard agar dilution method. For disk diffusion, the bacteria were directly suspended in saline and immediately swabbed onto 15-cm agar plates. Disks of cefoxitin (30 micrograms), chloramphenicol (30 micrograms), clindamycin...
