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

肺炎克雷伯杆菌产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.

这一现象在脲酶革兰氏阳细菌中就不会发，如肺炎链球菌或粪肠球菌。

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

腐葡萄球菌中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.

腐葡萄球菌也是脲酶（尿素酶）阳，这意味着它会产一种称为脲酶（尿素酶）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.

肺炎克雷伯杆菌脲酶阳，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酶，有助于保护它免受周围胃酸影响。

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尿素转化为氨和二氧化碳。

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.

但是一旦腐葡萄球菌进入泌尿系统，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：腐葡萄球菌是一种圆形、革兰染色阳、兼厌氧细菌，无运动能力、不形成孢子，且过氧化氢酶阳、凝固酶、脲酶阳，对新霉素耐药，它是已知会正常菌群一部分。
