Standardized antimicrobial disc susceptibility testing of anaerobic bacteria. I. Susceptibility of Bacteroides fragilis to tetracycline.
A modified Bauer-Kirby-Sherris-Turck method for disc susceptibility testing of anaerobic bacteria is presented. When tetracycline was used against 100 strains of Bacteroides fragilis as a model, reasonably reproducible results were obtained after overnight incubation in both the GasPak atmosphere and an atmosphere achieved by adding 10% CO(2) to a mixture of 10% H(2) and 90% N(2). The minimal i...
متن کاملAntimicrobial resistance and susceptibility testing of anaerobic bacteria.
Infections due to anaerobic bacteria can be severe and life-threatening. Susceptibility testing of anaerobes is not frequently performed in laboratories, but such testing is important to direct appropriate therapy. Anaerobic resistance is increasing globally, and resistance trends vary by geographic region. An overview of a variety of susceptibility testing methods for anaerobes is provided, an...
متن کاملComparative susceptibility of anaerobic bacteria to ticarcillin, cefoxitin, metronidazole, and related antimicrobial agents.
The in vitro antimicrobial activity of two newer agents, ticarcillin and cefoxitin, against 204 recent clinical isolates of anaerobic bacteria was determined by an agar dilution technique, and compared to their related compounds carbenicillin, cephalothin, and penicillin, as well as metronidazole, clindamycin, and chloramphenicol. Ticarcillin was similar to carbenicillin, and cefoxitin was more...
متن کاملComparative susceptibilities of anaerobic bacteria to metronidazole, ornidazole, and SC-28538.
The susceptibilities of 284 anaerobic bacteria, including 55 strains of the Bacteroides fragilis group, were determined by an agar dilution technique to metronidazole and two newer nitroimidazoles, ornidazole and SC-28538. All three agents showed marked in vitro activity against virtually all anaerobic bacteria tested. At concentrations </=1 mug/ml, SC-28538 was significantly more active than e...
متن کاملSusceptibility of anaerobic bacteria to carbenicillin.
One hundred and seventy-one strains of anaerobes were tested for susceptibility to carbenicillin by using agar dilution, broth dilution, and two disk diffusion methods. The minimal inhibitory concentration (MIC) for 67% of 51 strains of Bacteroides fragilis, 7 of 9 strains of Bacteroides melaninogenicus, and all of 8 strains of Eubacterium was 100 mug or less per ml. The MICs of the remaining a...
