So, with Klebsiella, urease makes urea dissociate into carbon dioxide and ammonia.

肺炎克雷伯杆菌生的脲酶使得尿素分解成二氧化。

This doesn't happen with urease negative Gram-positive cocci, like Streptococcus pneumoniae or Enterococcus faecalis.

这一现象在脲酶阴性的革兰氏阳性细菌中就不发生，如肺炎链球菌或粪肠球菌。

So, with Staph saprophyticus, urease makes urea dissociate into carbon dioxide and ammonia.

腐生葡球菌中的脲酶可使尿素分解为二氧化气。

Staph saprophyticus is also urease positive, meaning it produces an enzyme called urease that dissociates urea into carbon dioxide and ammonia.

腐生葡球菌也是脲酶（尿素酶）阳性的，这意味着生一种称为脲酶（尿素酶）的酶，能将尿素分解为二氧化气。

Alright, now Klebsiella pneumoniae is urease positive, which means it can produce an enzyme called urease that dissociates urea into carbon dioxide and ammonia.

肺炎克雷伯杆菌脲酶阳性，可以生脲酶，将尿素分解成二氧化。

For example, it produces an enzyme called urease that helps protect it from the surrounding gastric acid.

例如， 生一种称为脲酶的酶，有助于保护免受周围胃酸的影响。

In the urinary tract, Klebsiella can also use urease to convert the urea that's normally present in urine to ammonia and carbon dioxide.

在尿道中，克雷伯菌也可以利用脲酶将尿液中的尿素转化为二氧化。

These form when bacteria like Proteus mirabilis, Proteus vulgaris, and Morganella morganii use the enzyme, urease, to split urea into ammonia and carbon dioxide.

当细菌如变形杆菌、普通变形杆菌、摩根氏菌存在时就形成鸟粪石，细菌利用尿素酶将尿素分解成二氧化。

But as soon as Staph saprophyticus gets into the urinary system, it uses urease to hydrolyze urea into carbon dioxide and ammonia, which is an alkali.

但是一旦腐生葡球菌进入泌尿系统，就可以利用脲酶将尿素水解为二氧化碱性的气。

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，是已知的阴正常菌群的一部分。
