A total of 590 strains of clinically important anaerobes were tested to determine their susceptibility to trovafloxacin. Overall, trovafloxacin had a mode MIC of 0.25 micrograms/ml and a MIC at which 90% of the isolates were inhibited of 1 micrograms/ml and had activity comparable to that of metronidazole. Trovafloxacin was 8-, 8-, 16-, 32-, and 64-fold more active than ampicillin-sulbactam, clindamycin, ciprofloxacin, cefoxitin, and cefotetan, respectively. Of the Bacteroides fragilis group, 97% of the isolates were inhibited by trovafloxacin at 21 micrograms/ml, and trovafloxacin was more active than ciprofloxacin, cefoxitin, cefotetan, ampicillin-sulbactam, and clindamycin against Clostridium, Fusobacterium, Porphyromonas, and Prevotella strains.
共检测了590株具有临床重要性的厌氧菌，以确定它们对曲伐沙星的敏感性。总体而言，曲伐沙星的MIC模式值为0.25微克/毫升，90%的分离株被抑制时的MIC为1微克/毫升，其活性与甲硝唑相当。曲伐沙星分别比氨苄西林-舒巴坦、克林霉素、环丙沙星、头孢西丁和头孢替坦活跃8倍、8倍、16倍、32倍和64倍。在脆弱拟杆菌组中，97%的分离株在2微克/毫升时被曲伐沙星抑制，并且曲伐沙星对梭菌属、梭杆菌属、卟啉单胞菌属和普雷沃菌属菌株的活性高于环丙沙星、头孢西丁、头孢替坦、氨苄西林-舒巴坦和克林霉素。
