Four hundred thirty-eight bacteria cultured from specimens of patients with serious intra-abdominal infections were tested by agar dilution against trovafloxacin and other quinolones and antimicrobial agents. Trovafloxacin inhibited 435 strains (99.3%) at < or =2 microg/ml. All the quinolones had similar activities against Enterobacteriaceae and Pseudomonas sp., but trovafloxacin showed superior activities against streptococci, enterococci, and anaerobic organisms. Because of its excellent in vitro activities against diverse bacteria, trovafloxacin has potential use as a single agent for polymicrobial infections.
对从严重腹腔内感染患者标本中培养出的438株细菌，采用琼脂稀释法针对曲伐沙星、其他喹诺酮类药物及抗菌剂进行了测试。曲伐沙星在浓度≤2微克/毫升时可抑制435株菌株（99.3%）。所有喹诺酮类药物对肠杆菌科细菌和假单胞菌属的活性相似，但曲伐沙星对链球菌、肠球菌及厌氧菌显示出更强的活性。由于其对多种细菌具有出色的体外活性，曲伐沙星有潜力作为单一药物用于混合感染。
