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

但革兰氏染色阴性表现很弱，因此最好用银染色察。

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（革兰氏染色阳性），呈棒状：显微镜像一个巨大圆柱体或棒。

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.

钩端螺旋体是一种螺旋形病菌，革兰氏染色效果较差，因为它不能很好地保留染色剂，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.

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

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菌，在革兰氏染色上看起来像浅红色或粉红色逗号。

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色检测方法来发现菌，但它们无法识别内毒素，即便在菌不存在情况， 内毒素也可能存在。

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