    [MUSIC]
  • 00:00:03
    In his book “Microcosm” Carl Zimmer says… ow!
  • 00:00:07
    There’s an old saying about death by a thousand papercuts. But what if it just took one?
  • 00:00:16
    That’s silly, right? I mean, even if this DID get infected, we’ve got antibiotics
  • 00:00:20
    to clean us up, it's easy as aspirin. But that all might be about to change.
  • 00:00:26
    New types of antibiotic-resistant bacteria are starting to take over, some able to beat
  • 00:00:31
    every drug we throw at them.
  • 00:00:33
    [MUSIC]
  • 00:00:37
    We may be entering the post-antibiotic era, where something like this… could be the
  • 00:00:43
    end of me… all thanks to superbugs.
  • 00:00:47
    [MUSIC]
  • 00:00:56
    News flash! Everything is covered in bacteria. That. Definitely that. Oh yeah, they’re
  • 00:01:01
    ALL over that. In fact, even YOU are full of bacteria. You might
  • 00:01:05
    as well be a sentient sack whose main job is to carry around 100 trillion or so microbes.
  • 00:01:11
    But hey, at least you’ve got purpose!
  • 00:01:13
    Usually they aren’t anything to worry about, because most bacteria aren’t dangerous,
  • 00:01:17
    heck, some are even our friends. Thanks for helping me digest breakfast, guys!!
  • 00:01:21
    But sometimes, we meet the bad guys in the form of bacterial infections. But hey, no
  • 00:01:28
    problem, we’ve got antibiotics! A few pills, you’re back to normal, right as rain, ship
  • 00:01:33
    shape!
  • 00:01:34
    Unfortunately that might soon be a thing of the past. We’ve got armies of superbugs
  • 00:01:38
    laughing tiny bacterial laughs in the face of every drug we throw at them. How did this
  • 00:01:45
    happen? To understand that, we need to look at where antibiotics come from.
  • 00:01:49
    There’s probably more bacterial mass on Earth than every other living thing combined.
  • 00:01:53
    In one spoonful of soil, there might be more than a billion microbes of more than 10,000
  • 00:01:57
    different species, and not just bacteria but also microscopic fungi, some cooperating,
  • 00:02:03
    others locked in chemical warfare.
  • 00:02:05
    It’s that chemical warfare that allowed Alexander Fleming to discover the very first
  • 00:02:10
    antibiotic, by accident. While cleaning off his lab bench, he saw a
  • 00:02:14
    petri dish had become contaminated with mold, and on it all the bacteria had died, as if
  • 00:02:19
    the mold was secreting poison. That fungus was a strain of Penicillium, and
  • 00:02:24
    the antibiotic that was isolated from it, penicillin.
  • 00:02:28
    Early on doctors couldn’t purify enough of it to actually use it in humans. One of
  • 00:02:32
    the first patients to receive penicillin was a British policeman who developed a deadly
  • 00:02:36
    infection after being scratched by a rose bush in his garden.
  • 00:02:39
    He had to have that penicillin filtered out of his urine to get the next dose, that’s
  • 00:02:44
    how valuable it was. He ended up dying anyway, but the age of antibiotics had begun!
  • 00:02:49
    Since then, these drugs have saved millions of lives, maybe even yours! Thanks to them,
  • 00:02:55
    we can treat pretty much every disease that used to kill you in Oregon Trail.
  • 00:02:59
    But now that’s changed. Each year, nearly two million people in the U.S. become infected
  • 00:03:03
    with bacteria resistant to at least one antibiotic, and 23,000 of those people die.
  • 00:03:08
    Antibiotic resistant bacteria are here. Well, not HERE, here.
  • 00:03:15
    I hope.
  • 00:03:17
    So how does resistance work? Sometimes random mutations result in anti-antibiotic
  • 00:03:23
    superpowers, but bacteria are also able to swap genes the way we swap baseball cards,
  • 00:03:28
    thanks to a process called gene transfer, either sweeping up antibiotic resistance in
  • 00:03:32
    the genetic remains of dead bacteria or exchanging it during a sort of bacterial makeout session
  • 00:03:38
    we call conjugation.
  • 00:03:41
    Bacteria like Staphylococcus have gained the ability to rebuild their cell wall faster
  • 00:03:45
    than one antibiotic breaks it down. Other bacteria have “learned” how to make pumps
  • 00:03:50
    that flush antibiotics out of the cell before they do their job.
  • 00:03:53
    Even in 1945 Fleming himself had already seen bacteria become resistant to penicillin. Dunno,
  • 00:03:58
    maybe we shoulda seen this coming? Antibiotics we DO have today have come mainly
  • 00:04:03
    from the environment, we’ve adopted the natural weapons that microbes use to wage
  • 00:04:07
    war on each other… but that also means they’ve had billions of years to develop resistance.
  • 00:04:13
    It seems like wherever nature has developed an antibiotic, it's also developed a way to
  • 00:04:17
    fight it. Resistance seems like an inevitable result of evolution.
  • 00:04:22
    Of course we are doing our part to help the superbugs succeed.
  • 00:04:26
    Every year, hundreds of thousands of people are prescribed antibiotics for viral infections.
  • 00:04:31
    Antibiotics DO NOT KILL VIRUSES. Let me just repeat that: Antibiotics DO NOT KILL VIRUSES.
  • 00:04:38
    And every time you don’t finish your full prescription, you run the risk of leaving
  • 00:04:42
    super-strong stragglers behind. Special antibacterial soaps? NO! Soap is antibacterial
  • 00:04:49
    by definition, I promise. Those special additives do nothing to make
  • 00:04:54
    us safer, and probably make the bugs stronger.
  • 00:04:57
    So what can we do? With bacteria figuring out how to beat antibiotics
  • 00:05:00
    within years of their release, most drug companies aren’t super-motivated to invest the billions
  • 00:05:06
    it takes to develop new ones. In 2004 there were only 5 antibiotics in development.
  • 00:05:12
    But hope is not lost. Besides not getting infected in the first place, we need to research
  • 00:05:16
    new ways to fight bad bacteria, using materials that are naturally antimicrobial, or phage
  • 00:05:22
    therapy, which uses viruses that infect bacteria to fight infections.
  • 00:05:26
    We might even be able to use good bacteria to fight the bad, like using fecal transplants
  • 00:05:31
    to fight Clostridium difficile infections in the digestive system.
  • 00:05:35
    Yep… fecal transplants. Who would have thought that poop could be used as medicine?
  • 00:05:40
    We also have to look at where our food comes from. Factory farms use 80% of all antibiotics,
  • 00:05:46
    where they can contaminate the environment and drive the evolution of superbugs.
  • 00:05:50
    And stop prescribing them for viral infections! It’s a cold, people!
  • 00:05:53
    We’re playing a game of coevolution, an arms race, with our health at stake. Drugs
  • 00:05:59
    and bacteria are like cheetahs and gazelles, the cheetah gets faster, and the gazelles
  • 00:06:03
    have to speed up to survive. Except I think maybe we’re the gazelles,
  • 00:06:07
    and I’m not sure how much faster we can run.
  • 00:06:10
    I mean, did we learn nothing from Jurassic Park?
  • 00:06:14
    Let’s face it: Bacteria were here first. They’ve got like a 3 billion year head start
  • 00:06:20
    on this whole life thing, so it’s not surprising that they’ve worked out some pretty good
  • 00:06:24
    survival skills.
  • 00:06:25
    In the past 100 years, next to clean water and vaccinations, it’s likely that nothing
  • 00:06:30
    has saved more lives than antibiotics, but we’ve got some work to do to avoid a future
  • 00:06:35
    where paper cuts and sore throats are deadly. But hey, we’re pretty good at surviving
  • 00:06:41
    too.
  • 00:06:42
    Stay curious… and… go wash your hands.
