title: Activities of garenoxacin (BMS-284756) and other agents against anaerobic clinical isolates.
abstract: A total of 590 clinical isolates consisting of 33 species of both gram-positive and gram-negative anaerobes were collected from nine centers in the Chicago area in 1998-1999. The largest number of isolates (330 isolates, 56%) belonged to the Bacteroides group. Isolates were tested by agar dilution against garenoxacin (BMS-284756, T-3811 ME), trovafloxacin, moxifloxacin, clindamycin, imipenem, piperacillin-tazobactam, and cefoxitin. All but one species (2% of Bacteroides vulgatus isolates) were fully susceptible to piperacillin-tazobactam and imipenem. A number of species were resistant to clindamycin. Among the fluoroquinolones, garenoxacin and trovafloxacin had an MIC at which 90% of the isolates tested were inhibited of <4 micro g/ml for all but two species (Fusobacterium mortiferum/varium and Peptostreptococcus anaerobius).
