Agar dilution MIC testing of amoxicillin, amoxicillin-BRL 42715, amoxicillin-clavulanate, temafloxacin, and clindamycin against 496 beta-lactamase-producing anaerobic gram-negative rods revealed MICs for 90% of the strains tested of 256.0 (amoxicillin), 2.0 (amoxicillin-BRL 42715 and amoxicillin-clavulanate), and 4.0 (temafloxacin and clindamycin) microgram/ml. Amoxicillin, temafloxacin, and clindamycin inhibited all 44 beta-lactamase-negative strains (MICs for 90% of the strains tested, less than or equal to 2.0 micrograms/ml). BRL 42715 will not be developed, but temafloxacin merits clinical evaluation.
对496株产β-内酰胺酶的厌氧革兰氏阴性杆菌进行阿莫西林、阿莫西林-BRL 42715、阿莫西林-克拉维酸、替马沙星和克林霉素的琼脂稀释法最低抑菌浓度(MIC)测试,结果显示,90%受试菌株对阿莫西林的MIC为256.0微克/毫升,对阿莫西林-BRL 42715和阿莫西林-克拉维酸为2.0微克/毫升,对替马沙星和克林霉素为4.0微克/毫升。阿莫西林、替马沙星和克林霉素抑制了所有44株β-内酰胺酶阴性菌株(90%受试菌株的MIC小于或等于2.0微克/毫升)。BRL 42715不会再研发,但替马沙星值得进行临床评估。
