Staph saprophyticus is catalase positive, so it makes an enzyme called catalase.

腐生葡萄球菌是过氧化氢酶阳性的，它能产生一种称为过氧化氢酶的酶。

Finally, to distinguish Staph saprophyticus from Staph epidermidis, the novobiocin test is done.

最后，为了区分腐生葡萄球菌和表皮葡萄球菌，可行新生霉素试验。

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

腐生葡萄球菌中的脲酶可使尿素分解为二氧化碳和氨气。

We can use this to differentiate Staph saprophyticus from other gram positive cocci, like streptococci and enterococci, which are catalase negative.

我们可以利用这一特性来区分腐生葡萄球菌和其他革兰氏阳性球菌，如链球菌和肠球菌这一类过氧化氢酶阴性的细菌。

So, Staphylococcus saprophyticus are round bacteria that tend to live in grape-like clusters, and are commonly found on contaminated meat products.

综上，腐生葡萄球菌是一种圆形的、如葡萄串样生长的细菌，并且通常在受污染的肉制品上发现。

In fact, Staph saprophyticus is the second most common cause of UTI after Escherichia coli.

实际上，腐生葡萄球菌是继大肠杆菌之后导致尿路感染的次常见病原菌。

Staph saprophyticus can also form adherent biofilms on medical implants, typically the indwelling urinary catheters.

腐生葡萄球菌还可以在医疗植入物上，通常是留置导尿管上，形成粘附的生物膜。

Staph saprophyticus has a thick peptidoglycan cell wall, which takes in purple dye when Gram stained - so this is a gram-positive bacteria.

腐生葡萄球菌具有一层较厚的细胞壁，由肽聚糖构成，这使它在革兰染色时呈现为紫色，因此它是革兰氏阳性细菌。

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（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，能将尿素分解为二氧化碳和氨气。

So, if catalase is present, like in staph saprophyticus, it makes hydrogen peroxide dissociate into water and oxygen, making the mixture foam.

如果存在过氧化氢酶（如腐生葡萄球菌），它会使过氧化氢分解成水和氧气，使混合物出现泡沫。

Alright, now, people get Staph saprophyticus by eating contaminated meat - but this doesn't cause gastrointestinal disease.

人们通过食用被污染的肉类而感染腐生葡萄球菌，但这并不会引起肠胃疾病。

Staph saprophyticus infections can be treated with antibiotics like nitrofurantoin, or a combination of trimethoprim and sulfamethoxazole.

目前，腐生葡萄球菌感染可以用呋喃妥因等抗生素或联用甲氧苄啶与磺胺甲恶唑进行治疗。

With coagulase negative species, like Staph saprophyticus or Staph epidermidis, the fibrin doesn't clump up.

对于凝固酶阴性的细菌，例如腐生葡萄球菌或表皮葡萄球菌，纤维蛋白则不会结块。

A biofilm is basically a layer of " slime" made of exopolysaccharides or EPS, within which Staph saprophyticus live and reproduce.

这种生物膜通常是一层由胞外多糖（EPS）形成的“粘液”，腐生葡萄球菌在其中生存和繁殖。

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。

Furthermore, unlike many Staphylococcus species, Staph saprophyticus and its close relative, Staph epidermidis, are both coagulase negative, meaning they don't produce an enzyme called coagulase.

此外，与许多葡萄球菌不同，腐生葡萄球菌及其近亲表皮葡萄球菌，都是凝固酶阴性的，这意味着它们不会产生一种叫做凝固酶的酶。

This is when a disk imbued with Novobiocin, an antibiotic, is added to the culture, Staph saprophyticus is novobiocin resistant, so the colonies remain intact, whereas Staph epidermidis is novobiocin sensitive, so the colonies die off.

当装有新生霉素这种抗生素的培养皿被添加到培养物中时，由于腐生葡萄球菌对新生霉素抵抗，因此菌落保持完整，而表皮葡萄球菌对新生霉素敏感，因此菌落死亡。

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，它是已知的会阴正常菌群的一部分。
