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、摩根氏菌存在时就会形成鸟粪石，细菌利用酶将解成氨和二化碳。

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

肺炎克雷伯杆菌产生脲酶使得解成二化碳和氨。

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、革兰染色、兼厌细菌，无运动能力、不形成孢子，且过化氢酶、凝固酶阴、脲酶，对新生霉耐药，它是已知会阴正常菌群一部。

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

腐生葡萄球菌中脲酶可使解为二化碳和氨气。

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

在道中，克雷伯菌也可以利用脲酶将液中转化为氨和二化碳。

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

腐生葡萄球菌也是脲酶（酶），这意味着它会产生一种称为脲酶（酶）酶，能将解为二化碳和氨气。

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.

但是一旦腐生葡萄球菌进入泌系统，它就可以利用脲酶将水解为二化碳和碱氨气。

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

这一现象在脲酶阴革兰氏细菌中就不会发生，如肺炎链球菌或粪肠球菌。

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，可以产生脲酶，将解成二化碳和氨。

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

例如，它产生一种名为酶酶，有助于保护自己免受周围胃酸侵蚀。
