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 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 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 کاملBacteremia due to Bacteroides fragilis group: distribution of species, beta-lactamase production, and antimicrobial susceptibility patterns.
A retrospective analysis of susceptibility data on 542 blood isolates of the Bacteroides fragilis group tested from 1987 to 1999 by the same NCCLS-recommended broth microdilution method throughout is presented. Metronidazole, beta-lactam-beta-lactamase inhibitor combinations, carbapenems, and trovafloxacin were the most active agents (susceptibility of >or=93%). Among the cephalosporin-cephamyc...
