During the 1980s the emergence of multiple antibiotic-resistant strains of Staphylococcus aureus posed new problems for infection control worldwide, many of which still remain. In investigations of outbreaks of infection, the laboratory has a key role in identifying infected or colonised patients and staff. The rapid isolation and accurate identification of the causative organisms are essential for the implementation of appropriate control measures. Speed and accuracy in identification, by colonial morphology, is often difficult to achieve in the presence of a mixed population of commensal bacteria. To this end, the sensitivity of three media for the isolation of methicillin-resistant S. aureus (MRSA) from simulated clinical specimens was compared. Initial colonial recognition of MRSA was enhanced on methicillin-milk agar when compared with that on other media.
在20世纪80年代，耐多种抗生素的金黄色葡萄球菌菌株的出现给全球感染控制带来了新问题，其中许多问题至今仍然存在。在感染暴发调查中，实验室在识别感染或定植的患者及工作人员方面起着关键作用。快速分离和准确鉴定致病微生物对于实施适当的控制措施至关重要。在共生细菌混合菌群存在的情况下，通过菌落形态进行鉴定时，要实现速度和准确性往往很困难。为此，比较了三种培养基从模拟临床标本中分离耐甲氧西林金黄色葡萄球菌（MRSA）的敏感性。与其他培养基相比，在甲氧西林牛奶琼脂上对MRSA的初始菌落识别得到了增强。
