Finally, to distinguish Staph saprophyticus from Staph epidermidis, the novobiocin test is done.

最后，为了区分腐生葡萄球菌和表皮葡萄球菌，可行新生霉素试验。

With coagulase negative species, like Staph saprophyticus or Staph epidermidis, the fibrin doesn't clump up.

对于凝固酶阴性的细菌，例如腐生葡萄球菌或表皮葡萄球菌，纤维蛋白则不会结块。

The researchers found a diverse roster of bacterial residents, including a species of staph bacteria called staphylococcus epidermidis.

研究人员发现了不同种类的细菌，包括一种叫做表皮葡萄球菌的葡萄球菌。

Furthermore, unlike many Staphylococcus species, Staph saprophyticus and its close relative, Staph epidermidis, are both coagulase negative, meaning they don't produce an enzyme called coagulase.

此外，与许多葡萄球菌不同，腐生葡萄球菌及其近亲表皮葡萄球菌，都是凝固酶阴性的，这意味着它们不会产生一种叫做凝固酶的酶。

This is when a disk imbued with Novobiocin, an antibiotic, is added to the culture, Staph saprophyticus is novobiocin resistant, so the colonies remain intact, whereas Staph epidermidis is novobiocin sensitive, so the colonies die off.

当装有新生霉素这种抗生素的培养皿被添加到培养物中时，由于腐生葡萄球菌对新生霉素抵抗，因此菌落保持完整，而表皮葡萄球菌对新生霉素敏感，因此菌落死亡。
