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。

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。

Alright, as a quick recap: Staphylococcus saprophyticus is round, gram-positive, facultative anaerobic, non-motile, non-spore forming, catalase positive, coagulase negative, urease positive, and novobiocin resistant bacterium, which is known to be part of the normal flora of the perineum.

得！来快速回顾一下：腐生葡萄球菌是一种圆形的、革兰染色阳性的、兼性厌氧细菌，无运动能力、不形成孢子，且过氧化氢酶阳性、凝固酶阴性、脲酶阳性，对新生霉素耐药，它是已知的会阴正常菌群的一部分。
