A comparison was made of the in vitro activities of norfloxacin and of nine other orally administered antibacterial agents against 180 clinical isolates representing the bacterial species most frequently implicated in infections of the gastrointestinal tract in humans. The 90% minimal inhibitory concentrations showed norfloxacin to be 4, 15, 4, 17, 17, 17, and 33 times more active than the next best compound tested against Campylobacter fetus subsp. jejuni, Escherichia coli, Salmonella spp., Shigella spp., Vibrio cholerae, Vibrio parahaemolyticus, and Yersinia enterocolitica, respectively, with an overall 90% minimal inhibitory concentration of less than or equal to 0.5 micrograms/ml. Norfloxacin was least active against Clostridium difficile (90% minimal inhibitory concentration, 128 micrograms/ml). These results should encourage further evaluation of norfloxacin as a potential chemotherapeutic agent in the treatment of enteric bacterial infections for which antibiotic therapy is indicated.
对诺氟沙星和其他九种口服抗菌剂的体外活性进行了比较,它们作用于180株临床分离菌,这些分离菌代表了人类胃肠道感染中最常涉及的细菌种类。90%最小抑菌浓度表明,诺氟沙星对胎儿弯曲菌空肠亚种、大肠杆菌、沙门氏菌属、志贺氏菌属、霍乱弧菌、副溶血性弧菌和小肠结肠炎耶尔森菌的活性分别比下一个最佳测试化合物高4、15、4、17、17、17和33倍,总体90%最小抑菌浓度小于或等于0.5微克/毫升。诺氟沙星对艰难梭菌的活性最低(90%最小抑菌浓度为128微克/毫升)。这些结果应促使人们进一步评估诺氟沙星作为一种潜在化疗药物治疗需要抗生素治疗的肠道细菌感染的可能性。
