Pathogenicity 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 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...
متن کاملThe Bacteroides fragilis Group: The Next Superbugs in Waiting?
Treatment of infections caused by anaerobic bacteria remains largely empiric, despite recent knowledge and reduced antimicrobial susceptibility to commonly used antibiotics. The objective of this study was to obtain current surveillance data for the Bacteroides fragilis group in Australia. We obtained 255 faecal isolates, 100 derived from the community, 98 derived from hospital high-dependency ...
متن کاملActive efflux of norfloxacin by Bacteroides fragilis.
Norfloxacin was actively pumped out by Bacteroides fragilis, which is intrinsically resistant to most fluoroquinolones. Reserpine moderately inhibited the efflux. A one-step spontaneous mutant had increased resistance to norfloxacin, ethidium bromide, and puromycin, a result suggesting that the efflux is catalyzed by a multidrug pump with specificity similar to that of NorA/Bmr.
