Now, Legionella pneumophila has a very thin peptidoglycan layer, so it stains like a Gram-negative bacteria.

嗜肺军团菌的肽聚糖层很薄，所以虽然它是革兰氏阴性细菌。

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，通常可以帮助区分细菌的种类，判断它们是革兰氏阳性菌还是革兰氏阴性菌。

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。
