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

肺炎克雷伯杆产的脲酶使得尿素分解成二氧化碳和氨。

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就不会发，如肺炎链或粪肠。

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

的脲酶可使尿素分解为二氧化碳和氨气。

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

也是脲酶（尿素酶）阳性的，这意味着它会产一种称为脲酶（尿素酶）的酶，能将尿素分解为二氧化碳和氨气。

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

肺炎克雷伯杆脲酶阳性，可以产脲酶，将尿素分解成二氧化碳和氨。

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

例如， 它会产一种称为脲酶的酶，有助于保护它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，克雷伯也可以利用脲酶将尿液的尿素转化为氨和二氧化碳。

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

当细如变形杆、普通变形杆、摩根氏存在时就会形成鸟粪石，细利用尿素酶将尿素分解成氨和二氧化碳。

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.

但是一旦进入泌尿系统，它就可以利用脲酶将尿素水解为二氧化碳和碱性的氨气。

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：是一种圆形的、革兰染色阳性的、兼性厌氧细，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，对新霉素耐药，它是已知的会阴正常群的一部分。
