"tinción de Gram" in English

Viruses Video transcript - [Voiceover] Let's talk about how we can tincion de gram tell bacteria apart. We're going to pretend that we're the scientists or pathologists looking underneath a microscope to see these bacteria.

So here's something that they might be looking at, and you can see that there are five examples.

So let's just write down what we see. So vertically, in the top two at least, it looks purple, and on the right Tincion de gram can see that they're pink. And there's this thing I can barely see down here, so I'm just not going to write a color for now, but vertically, purple and pink.

So now let's look at the rows, and I can see that in the first row that they kind tincion de gram look like little circles, kind of maybe spherical.

So I'm just going to draw a circle here, and in the second row I can see that they're more stretched out and kind of like a tincion de gram. So I'm just going to draw this kind of stretched out oval-looking shape or a rod.

And this bottom area, I can barely see.

So since I've been using a light microscope for the top view, I'm going to use the opposite. It's called dark field microscopy, but don't worry too much about the name.

  • Bacterial characteristics - Gram staining

Just basically know that because these don't stain the tincion de gram way, they have to be viewed differently, and the best thing I can call this is a squiggle, and I hope that makes sense.

Let's go over that quickly one more time, before we get into the official names for these things. So first row, I can see that they're round, and that's a sphere, and in tincion de gram second row, it looks more like a stretched out rod-looking shape, and in the third row it kind of looks like a squiggle.

So the single version of this is coccus, or a bunch of them are called cocci. And a single rod is called a bacillus, whereas a bunch of them are called bacilli.

And tincion de gram single squiggle is called a spirochete, and the plural version is spirilla. So now we know about the three main shapes that bacteria can take, but tincion de gram haven't talked too much about the color yet, and this color comes from a special stain called the Gram stain, and it basically stains the outside of the bacteria.

And if it stains well, it stains purple, and if it gets washed off and stained with something else, it turns pink.

And if it stains purple, we call that Gram positive, whereas if it stains pink, the bacteria is called Gram negative. tincion de gram

So here I've done that with a positive sign and a negative sign. So we're going to take a closer look at tincion de gram color aspect.

So this tincion de gram look familiar to you, but this is just the general bacterial structure that we've gone over before.

And again, because the stain is only on the external layers of the bacteria, pay attention to just the external layer. So even though right here it says capsule, cell wall, and plasma membrane, you'll see in a minute that these layers are really tincion de gram between Gram positive or Gram negative bacteria, which is shown here actually.

So think of this as a zoomed in version of this peeled off bit.

It does have the plasma membrane layer, a really thick cell wall layer, and a capsule layer, but for Gram negative bacteria they actually have the plasma membrane again, but then they have a cell wall that is much thinner compared to Gram positive bacteria, and it's followed by another plasma membrane and then a special layer called a lipopolysaccharide tincion de gram and then a capsule.

And don't worry that you didn't quite catch all that right tincion de gram, because we're going to now draw them really zoomed in so you can see it.

So here is that plasma membrane, and remember that it's just a lipid bilayer with some integral membrane proteins which are drawn here tincion de gram little blocks.
