MICs of Bay 12-8039 and comparative antimicrobials were determined for 820 recent clinical isolates. Ciprofloxacin was approximately 2-fold more active than Bay 12-8039 and ofloxacin against Enterobacteriaceae and approximately 8-fold more active against Pseudomonas aeruginosa. Bay 12-8039 was approximately 2- to 16-fold more active than ciproiloxacin and ofloxacin against nonfermenters (except P. aeruginosa), staphylococci, streptococci, enterococci, and anaerobes. As determined by regression analysis, there was a high degree of correlation among quinolone MICs.
对820株近期临床分离菌株测定了Bay 12-8039及对照抗菌药物的最低抑菌浓度(MIC)。环丙沙星对肠杆菌科细菌的活性比Bay 12-8039和氧氟沙星高约2倍,对铜绿假单胞菌的活性高约8倍。Bay 12-8039对非发酵菌(铜绿假单胞菌除外)、葡萄球菌、链球菌、肠球菌和厌氧菌的活性比环丙沙星和氧氟沙星高约2至16倍。通过回归分析确定,喹诺酮类药物的MIC之间存在高度相关性。
