The Deadliest Being on Planet Earth - The Bacteriophage


  • You like our art and want to put it on your wall? Look no further:

    • He protec He attack But most importantly... He infec

    • The bacteriophage art reminded of Steven Universe, heh.

    • Ohkay

    • Maestrul Gamer HIV is also phase n it attacks on human cell .yaaa it's bigger problem.


  • Pardon me, i think im gonna go freak out now.

  • This video is awesomeee.

  • nah they got d20s for heads they’re all just nerds who want revenge on the popular ppl who bullied them in high school

  • Phages are one of our ally to kill those Bacteria.


  • How do i find out more about this?

  • Imagine if Phages evolve to be able to destroy human cells

  • Am I the only one who thinks that something or someone artificially created the bacteriaphage?

    • Russia created this sercet virus to kill bacteria.

  • Fuck that dude.. Let's see if Bill Gates inject that shit in himself first. The Best Cure to illnesses. It's simply not curing at all. Let's leave the body do it's job.

  • Please for the love of god, never change the narrator. Definitely my favorite parts of the video. Along w the animations ofc

  • Putting the deadliest being on earth into the second deadliest being's body doesn't sound like a great idea i just hope it work's

  • This video makes me paranoid

  • but wait are'nt AIDS a virus

  • Incredible!!!!!! Must thank these genius scientists on figuring out cures and using deadly organisms to cure other serious illness and diseases! I adored the animation, and the person explaining everything about the Phages to us! This is just..... Amazing!

  • CAN THERE BE VIRUOPHAGES!?!?!?!?!?!?!?!?!?!?!?!?!? (noob I know there is not but I may be wrong)

  • So it's a living virus?

  • Yeah, just some Steven Universe crap that happened in the kindergarten

  • I watch these videos on the daily. Christ. It’s so fucking good

  • hhmmmmmmmmmmmmm........ intresting

  • You know, I've watched a lot of this channels videos, and in that time I've found the best way to summarize them. HOLY CRAP SCIENCE IS CRAZY AND AMAZING

  • me at school: PRAISEEEEEEE BACTERIA PHAGES ALL OF U KIDS everyone else: ?? ???????

  • *Phage Wars: Immunity Crisis would be a great name for a game based on this*

  • Weird fact: As I was studying yesterday this type of phage for a test, I kept thinking: “why we couldn’t use them to kill bacterial infections.” And then I see that is already a thing

  • heres the thing though, what if phages evolve to harm us?

  • Holly Crap... Sponsored by Microsoft

  • Fascinating

  • Found my fave bacteria

  • Imagine in the far future when using phages have gone mainstream and they evolve to convert human cells and people just started bursting and releasing more of those phages that spread and bursted more people

  • What is Phages are like Trojan horses made by aliens?

  • Wait so we use the deadliest virus (Phage) to keep the deadliest parasite (human) alive. Somehow nature fucked up with us, killing everything that could harm us. Hopes up for something like the dinosaurs had...

  • this made me smile

  • Bacteria: Mission failed! We'll get'em next time.


  • Why not 4K?

  • Call me stupid but what would happen with the bacteriophages after they killed the bacteria in a person would they just stand there until another comes around or start attacking the good bacteria?

  • That just brought my hopes up definitely subscribing 😸

  • It's just a Phage mom!!

  • you said they would also kill good bacteria so the phages aren't that good

  • It's a bit simular to smallpox

  • Anyone here remembers that creepy episode from Jimmy Neutron?

  • That virus reminds me of the episode of Jimmy Neutron

  • kurzgesagt rule 34

  • This video is so amazing! It's exactly what we've learned in biology class, but only in 7 minutes! The animation and the voice over are incredible :)

  • Galactus, is that you

  • This wouldn't help with viral infections, though, right?

  • What if Phages develop a taste for human cells?

  • Wow what a plot twist!

  • Hi ich bin deutscher und habe gehört ihr eigentlich ein deutscher Kanal Seit, was euren deutschen Namen erklärt. Ich liebe eure Videos und finde es schade, dass die deutschen eure Videos nicht würdigen. Ihr könnt wunderbar animieren und wirklich geil Dinge erklären. Macht weiter so und ich finde jedes euerer Themen unglaublich interessant. Daumen hoch

  • Could you make a video about thorium-based nuclear power?

  • So these are like really tiny face huggers?

  • THIS IS SO COOL! And it’s we need to get their help now!

  • more theme like these pls :)

  • The only problem is the what ever its name is well also destroy our probiotics too which we need!

  • This is my first time watching this channel. Usually I just go to reallifelore etc to watch some amazing videos. But this channel is too amazing with its captions, animations and contents. I love this

  • um but not all of dangerous bacterias have their own phage right?

  • Yeah that's great but what about superpopulation?

  • What if the phages attack white blood cells?

  • Learn2Language

  • What if the phages were to evolve to target human cells?

  • I like the music going with this.

  • So if these were injected into your body would there be a possibility for them to attack other bacteria in your body? Also would you only need one injection or will your body target the virus and kill it off?

  • very entertaining to watch and learned a bit as well Ty.

  • I thought Logan Paul is the most dangerous

  • Yeah, but what is the phage of a phage?

  • God I love your stuff!

  • Subscribed instantly. Your visuals feel so nice to the eyes. The commentary is good and informative

  • Phage Clan > Faze Clan

  • Better call Darius, because I've got some Phages now, boy.
