You've got a lot of pressure favoring antibiotic resistance, so you get increased virulence leading to the evolution of increased antibiotic resistance.

Just some antibiotics.

Antibiotics.

So, we can go to the same countries and look and see.

But if we look at the end of the 1990s, just half a decade later, we see that in Ecuador they started having a resistance problem.

Antibiotics. I just got a...

Antibiotic.

I don't know if you know this, but bacteria can actually exchange DNA.

Surgical instruments, alcohol, rubber gloves, rubber sheets.

Okay, try this one! I want you to take a syringe and some antibiotic for David.

I'm going to give you some example.

If you've got a harmful organism, a high proportion of the people are going to be symptomatic, a high proportion of the people are going to be going to get antibiotics.

One of my big soapboxes right now is antibiotics.

Let's give him 2 grams of oxygen. What's his hemoglobin?

Because she has been suffering from a superbug called C. diff, and it's resistant to antibiotics in many cases.

What happened, Major? Apparently, Dr. Brookmyre sent his nurse out with some of the antibiotics.

If you could cause an evolutionary decrease in virulence by cleaning up the water supply, you should be able to get an evolutionary decrease in antibiotic resistance.

But there's another really interesting aspect of this, and this is that if you could control the evolution of virulence, evolution of harmfulness, then you should be able to control antibiotic resistance.

Antibiotic sensitivity was going down.

They came to told me, I have to save him.

What to do next? Don't know.

And fortunately he didn't die.

So people are really into cleanliness, right?

And once you get increased antibiotic resistance, the antibiotics aren't knocking out the harmful strains anymore.

There's more.

Keep taking the antibiotics.

Antibiotics are hard to come by these days.

Some of these infections are actually carrying antibiotic resistance genes now, and that makes them even more difficult.

Day 21, day 23, day 25.

First of all, that bullet has to come out.

And the result of it is, we have diseases.

P.T. can handle the antibiotics.

And guess what, it's not our grandparents' chicken either.

When it comes to supplements, should you be taking them?

They got the organism to evolve to mildness, and they got no development of antibiotic resistance.

The doctor dosed the girl with antibiotics.

In the center of this graphic is the arsenic that gets recycled.

And with that entire wealth of England,

Anti biotics. Actually I don't think there is a hyphen Antibiotics.

I sent her with some antibiotic for the father.

Yeah, but he's on I.V. antibiotics.

What is effective? What is the right thing to do?

So then what happened, is we are learning in biology classes, we're supposed to be paying attention to antibodies.

The antibiotic resistance story has already been laid out in great detail.

Brookmyre said it wasn't an antidote, just a strong antibiotic.
