The susceptibilities of 347 urine isolates of enterococci (Streptococcus faecalis, 44%; S. faecalis subsp. zymogenes, 37%; S. faecalis subsp. liquefaciens, 19%) to ampicillin, azlocillin, mezlocillin, piperacillin, vancomycin, gentamicin, erythromycin, rosaramicin, rifampin, rifampin plus trimethoprim (1:4), trimethoprim-sulfamethoxazole (1:20), and chloramphenicol were determined by the agar dilution technique. There were no significant differences in susceptibility to individual agents among the subspecies of S. faecalis. Azlocillin and mezlocillin (MIC for 90% of isolates, 0.78 micrograms/ml) and piperacillin, ampicillin, and vancomycin (MIC for 90% of isolates, 1.56 micrograms/ml) were the most active agents and were significantly more potent than the other reference antibiotics tested.
采用琼脂稀释法测定了347株肠球菌（粪肠球菌占44%；发酵粪肠球菌亚种占37%；液化粪肠球菌亚种占19%）尿液分离株对氨苄西林、阿洛西林、美洛西林、哌拉西林、万古霉素、庆大霉素、红霉素、罗沙米星、利福平、利福平加甲氧苄啶（1:4）、甲氧苄啶-磺胺甲恶唑（1:20）和氯霉素的敏感性。粪肠球菌各亚种对各药物的敏感性无显著差异。阿洛西林和美洛西林（90%分离株的MIC为0.78微克/毫升）以及哌拉西林、氨苄西林和万古霉素（90%分离株的MIC为1.56微克/毫升）是活性最强的药物，且比所测试的其他参考抗生素效力显著更强。
