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

腐生葡萄菌中的脲酶可使尿素分解为二和氨气。

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会发生，如肺菌或粪肠菌。

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

肺克雷伯菌产生的脲酶使得尿素分解成二和氨。

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

腐生葡萄菌也是脲酶（尿素酶）阳性的，这意味着它会产生一种称为脲酶（尿素酶）的酶，能将尿素分解为二和氨气。

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

例如，它产生一种名为尿素酶的酶，有助于保护自己免受周围胃酸的侵蚀。

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为氨和二。

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

当细菌如变形菌、普通变形菌、摩根氏菌存在时就会形成鸟粪石，细菌利用尿素酶将尿素分解成氨和二。

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

肺克雷伯菌脲酶阳性，可以产生脲酶，将尿素分解成二和氨。

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.

但是一旦腐生葡萄菌进入泌尿系统，它就可以利用脲酶将尿素水解为二和碱性的氨气。

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：腐生葡萄菌是一种圆形的、革兰染色阳性的、兼性厌细菌，无运动能力、不形成孢子，且过氢酶阳性、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。
