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，破伤风梭菌显紫色（革兰氏染色），棒状：显微镜下外观像一个巨大圆柱体或棒子。

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

我们可以利用这一特来分腐生葡萄球菌和其他革兰氏球菌，如链球菌和肠球菌这一类过氧化氢酶阴菌。

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

胞壁由肽聚糖组成，通常可以帮助分菌种类，判断它们是革兰氏菌还是革兰氏阴菌。

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.

保护菌胞壁决定了菌是革兰氏菌还是革兰氏阴菌，并且参与维持菌形状。

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

在革兰氏菌中， 这一层构成了胞壁一部分，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.

无膜革兰氏菌在显微镜下可见保留紫色染色。
