But it stains pretty weakly as a Gram-negative bacteria, so it's best visualized with silver stain.

但革兰氏染阴性表现很弱，因此最好用银染。

V. cholerae is a gram-negative, curved bacteria which looks like little red or pink comma-shapes on a gram stain.

霍乱弧菌是革兰氏阴性弯曲细菌，在革兰氏染上看起来像浅红或粉红逗号。

Still growing. Nothing on Gram Stain. It looks like meningitis.

革兰氏染也有什么结果 看上去象脑膜炎。

Now, Leptospira is a tiny spiral bacteria, that stains poorly with Gram staining, because it doesn't retain the Gram dyes well, so it's classically considered gram-negative.

钩端旋体是一种细旋形病菌，革兰氏染效果较差，因为它不能很好地保留染剂，所以通常认为它是一种革兰氏阴性菌。

In the lab, when doing a gram stain, Clostridium perfringens is Gram-positive, or purple when Gram stained, and look like big cylinders or rods, also called bacilli.

实验室做革兰氏染时，产气荚膜梭菌显紫（革兰氏阳性）：很像个大圆柱或棒子，因此也叫杆菌。

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.

革兰氏染中，破伤风梭菌显紫（革兰氏染阳性），呈棒状：显微镜下外像一个巨大圆柱体或棒子。

We do have tests called gram stains that detect bacteria, but they can't recognize endotoxins, which can be there even when bacteria aren't present.

我们确实有称为革兰氏染检测方法来发现细菌，但它们无法识别内毒素，即便在细菌不存在情况下， 内毒素也可能存在。
