It’s a facultative anaerobe so that means it can undergo respiratory and fermentative metabolism.

它是兼性厌菌，这意味着它可以经历呼吸和发酵代谢。

That makes the environment on the enamel surface favorable for facultative anaerobic bacteria, which can metabolize sugars with and without oxygen present.

这使牙釉质表面环境有利于兼性厌菌生存；兼性厌菌即使在缺况下也可以代谢糖类。

It’s non-motile and doesn’t form spores, and also, it’s a facultative anaerobe, meaning that it can live with or without oxygen.

它没有运动能力，也不会成孢子，同时，它也是兼性厌细菌，意味着它可以在有条件下生存。

Alright, as a quick recap: Klebsiella pneumoniae is a Gram-negative bacillus, non-motile, non-spore forming, facultative anaerobe, urease positive, and lactose fermenter, which forms mucoid pink colonies on MacConkey agar.

得！快速回顾一下：肺炎克雷伯杆菌是一种革兰氏阴性杆菌，非运动性、芽孢兼性厌菌，脲酶阳性，可发酵乳糖，在MacConkey琼脂培养基上成粘性粉红色菌落。

It’s a non-spore forming, aerobic, facultative intracellular, catalase and oxidase positive bacteria that is best visualized with silver stain and grows well on BCYE agar with cysteine and iron into grey-white colonies with a cut-glass appearance.

它是非芽孢、需、兼性细胞内寄生、化酶和过化氢酶阳性细菌；最佳观察方式是银染色；在BCYE培养基供给半胱氨酸和铁况下生长良好，可成雕花玻璃样灰白色菌落。

Legionella pneumophila is non-spore forming, aerobic, which means it needs oxygen to survive, facultative intracellular, which means it can survive both inside and outside the cell, and oxidase and catalase positive, which means it produces both of these enzymes.

嗜肺军团菌是一种非芽孢好细菌，需要气才能存活，也是兼性细胞内寄生菌，即它在细胞内外均可生存，化酶和过化氢酶阳性，即它可以产生这两种酶。

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、革兰染色阳性、兼性厌细菌，运动能力、不成孢子，且过化氢酶阳性、凝固酶阴性、脲酶阳性，对新生霉素耐药，它是已知会阴正常菌群一部分。
