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.

兰氏染中，破伤风梭菌显（兰氏染阳性），呈棒状：显微镜下外观像一个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.

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

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

由肽聚糖组成，通常可以帮助分菌的种类，判断它们是兰氏阳性菌还是兰氏阴性菌。

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.

保护菌的决定了菌是兰氏阳性菌还是兰氏阴性菌，并且参与维持菌的形状。

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

在兰氏阳性菌中， 这一层构成了的一部分，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.

无膜的兰氏阳性菌在显微镜下可见保留染。
