What causes antibiotic resistance? - Kevin Wu

Explore how bacteria become resistant to antibiotics and turn into superbugs, and what scientists are doing to stop it.

--

Right now, you are inhabited by trillions of microorganisms. Many of these bacteria are harmless (or even helpful!), but there are a few strains of ‘super bacteria’ that are pretty nasty -- and they’re growing resistant to our antibiotics. Why is this happening? Kevin Wu details the evolution of this problem that presents a big challenge for the future of medicine.

Wait did DNA just fly out of his butt 2:24

I love the bacteria farting part. very creative!

As a medical student, I approve of this video.

Narrator: blah blah blah deadly epidemic
Me: hMm sOUndS fAmiLaR

I would also like to know what a floating purple ball with a bow does for our body 😂😂😂

Why it takes millions of years to us to evolve, but only a few hours in bacteria? ( i know the answer but just acting smartass here)
Could we use that speed up in evolution that bacteria have in bigger and more complex organisms?

love the animations in this video lol

Thank you for the interesting video but I have had a Colon operation due to ear infections and bad bacteria in my body for the last 50 odd years and still on going on and off from antibiotics from time to time and as I am getting older in my pension years I can feel I am getting weaker thank you so much for sharing this video did not know any information about antibiotics until I could feel it and now your video thank you @ Ted-Ed 👍👍😀😀🌹🌹❤️❤️

Thank you for this video, I am doing a little big idea thing with my school

[pinkribbon]

We don't thank scientists enough sometimes

Information about overuse of antibiotics in animals AND humans would be a really necessary information. Same goes to the bad compliance of patients by stoping treatments to early.

[JCrandall-ll]

The illustration of the E. coli bacteria is so disturbing I want to cry

[baileyryan]

This channel is better than going to school

[TheRandomvideos]

2:24 Lol and the bacteria's face!

[shivambhonsle]

I LOVE YOU GUYS SOO MUCH, THIS REALLY HELPED FOR SOME WORK I WAS DOING

[scpf]

Antibiotics DO NOT work on viruses, such as those that cause colds, flu, or COVID-19. Antibiotics also are not needed for many sinus infections and some ear infections. When antibiotics aren't needed, they won't help you, and the side effects could still cause harm.

I see Professor Untonium in there on 3:33. I see your secrets TED-Ed.

[parthapratimsikdar]

I was not ready for the farting part😂😂😂

[asdfghj]

2:45 i cant be the only one thinking that

Due to random mutations, different characters exist and compete. They may strike a balance according to environment. However, the overusing of antibiotics in the 20th century rendered the patent edge to survive of resisitant-bacterias over non-resistant ones. As a result, resistant-bacterias become majority while they used to be minority before the appearance of antibiotics. Therefore, some antibiotics used to be rather effective but now cannot make any difference.

What is Professor Utonium doing at 3:40 😂
