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。

Testing for coagulase is done by transferring a colony of the suspected bacteria into a test tube containing fibrinogen-rich plasma.

通过将待测细菌的菌落转移到装有富含纤维蛋白原血浆的试管中可对凝固酶进行测试。

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。

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。
