There is presently no accepted method for marking individual strains of Staphylococcus epidermidis. Consequently, five parameters for distinguishing such strains were examined and compared for their epidemiological efficacy: biotyping, serotyping, proteinase grouping, aminopeptidase profiles and antibiograms. Both biotyping and proteinase grouping were of limited use in identifying a particular strain, although they were helpful in initially categorizing such strains. Antibiograms were least useful because of similarities in susceptibility patterns among isolates. Serotyping and amino-peptidase profiles provided the best means of identifying an individual strain for epidemiological use. The applicability of these typing methods was demonstrated during a one year epidemiological study at a chronic disease hospital.
目前尚无公认的标记表皮葡萄球菌单个菌株的方法。因此，研究并比较了区分此类菌株的五个参数的流行病学效力：生物分型、血清分型、蛋白酶分组、氨肽酶谱和抗菌谱。生物分型和蛋白酶分组在鉴定特定菌株方面用途有限，尽管它们有助于初步对此类菌株进行分类。抗菌谱最无用，因为分离株之间的药敏模式相似。血清分型和氨肽酶谱为鉴定用于流行病学研究的单个菌株提供了最佳方法。在一家慢性病医院进行的为期一年的流行病学研究中证明了这些分型方法的适用性。
