Twenty-four strains of Staphylococcus aureus, including eight known mutants of S. aureus and strains growing under a variety of environmental conditions or exposed to a number of physical and chemical agents, maintained a remarkably narrow range of guanine plus cytosine (GC) content (32.4 to 35.1%). The wide range of GC content (30.7 to 40%) reported in the literature was due to the variety of methods and calculations used rather than to any substantial variation in base composition. The UV-2 "mutant" (ATCC 13680) with a GC content of 67.6% reported to be derived from S. aureus (ATCC 13679) was a species of Corynebacterium. The data presented were consistent with the concept that base composition changes only to a very slight degree by mutation.
24株金黄色葡萄球菌，包括8株已知的金黄色葡萄球菌突变体以及在各种环境条件下生长或暴露于多种物理和化学试剂的菌株，其鸟嘌呤加胞嘧啶（GC）含量范围非常狭窄（32.4%至35.1%）。文献中报道的GC含量范围较宽（30.7%至40%）是由于所使用的方法和计算方式的多样性，而非碱基组成存在任何实质性差异。据报道，GC含量为67.6%的UV - 2“突变体”（ATCC 13680）源自金黄色葡萄球菌（ATCC 13679），但它实际上是棒状杆菌属的一个物种。所呈现的数据与碱基组成仅因突变而发生非常轻微变化这一概念相一致。
