The antibacterial activities of nitazoxanide and its main metabolite, tizoxanide, were tested against a broad range of bacteria, including anaerobes. Metronidazole, amoxicillin, amoxicillin-clavulanic acid, piperacillin, cefoxitin, imipenem, and clindamycin were used as positive controls. MICs were determined by reference agar dilution methods. The 241(More)
We compared the susceptibility results for 200 clinical anaerobes with nine antibiotics obtained by using a new ATB ANA (bioMérieux) device against those obtained by the National Committee for Clinical Laboratory Standards (NCCLS) standard agar dilution method. For better evaluation of the device, we added some resistant Bacteroides fragilis group strains(More)
As recommended by the EEC, the in vitro activity of a veterinary quinolone has to be evaluated on human strains isolated from the gut and especially against anaerobes. Thus, the MICs for Marbofloxacin were determined by the reference agar method (Norma NCCLS M11 A3) using Wilkins Chalgren medium for the 124 anaerobic strains and Mueller Hinton agar for E.(More)
A simple, rapid and reliable method that can be used to test individual isolates in routine is needed. Two systems are now marketed in France. As these two methods have not been studied extensively and never compared, the aim of our study was to evaluate them concurrently. For that 56 anaerobes were collected, including 31 Bacteroides fragilis group(More)
During 1994, the in vitro antibiotic susceptibility of 306 anaerobic bacteria was performed in 4 hospitals, by the reference agar dilution method. Among the 129 B. fragilis group strains, only two B. fragilis strains were resistant to the three carbapenems and all beta-lactams, even combined with beta-lactamase-inhibitors while metronidazole resistance(More)
The activities of the pristinamycin and its two components (RP 12536 and RP 27404) were investigated using the reference agar dilution method M11A3, on 175 anaerobic strains in comparison with that of erythromycin, clindamycin, metronidazole, amoxycillin either alone or combined with clavulanic acid, piperacillin, cefoxitin, cefotetan and cefotaxime.(More)
