A method is described which may be used to compare the relative activity of beta-lactam antibiotics against gram-negative bacilli. The method offers several important advantages over conventional methods of evaluation of the antibacterial activity of beta-lactam agents: the bacterial inoculum is simply and accurately standardized; the response of the culture is continuously monitored and information is obtained on both the intrinsic activity of the agent and its susceptibility to enterobacterial beta-lactamases. In this way, differences in the antibacterial activity of compounds which appear similar on the basis of more conventional tests may be revealed.
本文描述了一种可用于比较β-内酰胺类抗生素对革兰氏阴性杆菌相对活性的方法。与评估β-内酰胺类药物抗菌活性的传统方法相比,该方法具有几个重要优点:细菌接种量简单且准确地标准化;对培养物的反应进行持续监测,并获得有关药物内在活性及其对肠杆菌β-内酰胺酶敏感性的信息。通过这种方式,可以揭示在更传统测试中看似相似的化合物在抗菌活性方面的差异。
