trends in antimicrobial resistance of the bacteroides fragilis group: a 20-year study at a medical center in buenos aires, argentina. 19979310702
["in vitro" activity of ten antimicrobial agents against anaerobic bacteria. a collaborative study, 1999-2002].the antimicrobial activity of ampicillin, ampicillin-sulbactam, cefoxitin, ceftriaxone, imipenem, piperacillin, piperacillin-tazobactam, clindamycin, metronidazole, and azitromycin was assesed against 166 strains of anaerobic bacteria recovered from eight hospitals in buenos aires. the strains studied were bacteroides fragilis group (65), fusobacterium spp. (26), prevotella spp. (21), porphyromonas spp. (10), clostridium difficile (10), other clostridia (12), and gram-positive cocci (22). the mi ...200415559195
susceptibility trends of bacteroides fragilis group isolates from buenos aires, argentina.the aim of this study was to analyze the susceptibility trends to seven antibiotics of bacteroides fragilis group isolates based on three survey studies performed by the committee of anaerobic bacteria between 1989 and 2002. fifty three, 82 and 65 b. fragilis group isolates were collected during each period. the antimicrobial agents included were: ampicillin, ampicillin-sulbactam (2:1), cefoxitin, piperacillin, imipenem, clindamycin, and metronidazole. minimal inhibitory concentrations (mics) we ...200717987852
