Now, Legionella pneumophila can enter the body through inhalation of contaminated water droplets.

嗜肺军团菌可以通过受污染水滴被吸入人体。

Now, Legionella pneumophila causes a disease called legionellosis which has two distinct entities.

嗜肺军团菌可以引起两种不同的军团菌病。

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。

Alright, as a quick recap: Legionella pneumophila is a Gram-negative bacillus found in water systems.

得！快速回顾一下：嗜肺军团菌是一种存在于供水系统中的革兰染色阴性菌。

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氧细菌，需要氧气才能存活，也是兼性细胞内寄生菌，即它在细胞内外均可生存，氧化酶和过氧化氢酶阳性，即它可以产生这两种酶。

There are also more unusual bacteria like mycoplasma pneumoniae, chlamydophila pneumoniae, and legionella pneumophila, which don't have a cell wall and are well known for causing an " atypical or walking pneumonia" because they often cause vague symptoms like fatigue.

还有一些更不寻常的细菌，如肺炎支原体、肺炎衣原体以及嗜肺军团菌，它们没有细胞壁，且因引起“非典型肺炎”而臭名昭着，因为它们通常会引起一些模糊的症状，如疲劳。
