When doing a Gram stain, Clostridium tetani stains purple— or gram positive— and it's a bacillus, meaning that it looks like a big cylinder or rod under the microscope.

革兰氏染色中，破伤风梭显紫色（革兰氏染色阳性），呈棒状：显微镜下外观巨大的圆柱体或棒子。

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

我们可以利用特性来分腐生葡萄和其他革兰氏阳性，如链和肠类过氧化氢酶阴性的细。

It consists of peptidoglycan which usually helps differentiate whether bacteria are gram positive or gram negative.

细胞壁由肽聚糖组成，通常可以帮助分细的种类，判断它们是革兰氏阳性还是革兰氏阴性。

They have a cell wall which protects the bacteria, determines whether they are gram positive or gram negative bacteria and also helps maintain their shape.

保护细的细胞壁决定了细是革兰氏阳性还是革兰氏阴性，并且参与维持细的形状。

In gram positive bacteria this layer forms part of the cell wall, so penicillin can easily attack it.

在革兰氏阳性细中， 层构成了细胞壁的部分，因此青霉素能够轻易攻击它。

Bacteria with no membrane, gram positive, retain the purple staining visible under a microscope.

无膜的革兰氏阳性在显微镜下可见保留紫色染色。
