The Deadliest Being on Planet Earth - The Bacteriophage


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

    • do phages kill good bacteria

    • Can they kill immune cells?

    • What if the fages become a danger to our cells?

    • Well it doesn't have any power to kill cancer but I'm glad it exists to kill those other bad diseases.

    • Kurzgesagt - In a Nutshell . Can phages defeat cancer ?

  • Viruses are not predators. They don't "seek" out hosts. They just "fall into them by random". They are not alive. They also have no means of moving around. They bounce around randomly like dust.

  • “Micro war”

  • Awesome name for a band!

  • The most difficult part about telling people about phages is changing their perceptions. Most automatically think "bad" or "evil" whenever they hear the word "virus". When, in fact, as with bacteria, there are good ones as well as bad ones. Education is key.

  • I guess killer beings such as us and bactiophage get along...

  • If we inject them into us and they kill all the bacteria, wouldn’t they try to evolve and find ways to kill our cells?

  • Phages look like microscopic Protoss units

  • This makes me smile knowing these little diamond heads will save us lol

  • I mean 30

  • I was don’t want to know I will die in 60 years

  • I thought this was for chlildren

  • I just got this random thing in my head when I saw this 5:08 I think it should be a game called phage vs super bacteria

  • This is very good series better than others

  • What happens If the virus mutates an begins to infect us Lol ☠️💀

  • so is good or bed?

  • "We still might be able to win" "INGECT MORE"

  • I believe in 2050, we will be about ten times stronger than phages

  • They are not harming US they kill harmful

  • A big problem is that pharmaceutical companies would find it more difficult to profit from these because intellectual property around infection-specific phages is not as straight-forward as antibiotics. I'm not sure if this would therefore be the right place for government-funded development instead.

  • Oh yes so very good i shall call the army of phages HAIL HYDRA!!!!!!!

  • *world war cells*

  • I bet my friend is like, OMG SHES WATCHING A VIDEO ABOUT ME

  • Damn


  • Fascinating.

  • WOW!

  • holy shit. what if bacteria phages were about the size of dogs. they can terrafuck us all to our fuckin' graves

  • 5:58 they can even survive an alcoholic handjob

  • This is world war 2. The bacteria is the nazis and the antibodies, Bacteriophages, and humans were the allies

  • biggest save ever i thought we dead for sure from superbugs

  • it’s basically the White Blood Cell Of Our Outside Body?

  • "we used antibiotics more and more..." - no, agriculture used it more and more on cattle to increase their growth rate. This is where most of the cases of resistant bacteria in Holland come from. Another source are populations with ready access to antibiotics without a doctor's prescription. A lot of countries including the USA and the countries in southern Europe are in this range. They create their own problems. Russia creates even worse problems for itself by having prison populations that are both overcrowded, get *some* medication but not enough. Resistant tuberculosis is a real risk inside Russian prisons. Don't get me started on South America. And the fools that think "oh, it's just prisoners..." - well, they do get out at some point and then infect the general population. Having good healthcare was created by people who didn't like dying from poor people's plagues. Apparently, that lesson is forgotten. And pharma has no reason to reminds us of it, as the antibiotics sold to agriculture and humans alike create massive profits. But IMO, they should be reserved for cases where a test confirms a bacterial infection, and nothing else.

  • 5:12 *Wilhelms Scream* . Get out xD

  • Bacteria Hitler

  • So phages, in some extreme cases, can be (theoretically) destroy cancer cells, etc

  • Bacteriophage are great

  • So ww1 happened billions of years ago when Bacteriophages were deadlier than humans

  • 5:11 Bacterihelm scream

  • If it is called the deadest being on earth then why does it save people’s life instead of killing them

  • This video helped me learn

  • I think in Philippines had no bacteria we know to wash our hands with out soap

  • Antibiotic are use mostly for food production, cattle,pigs,and chicken that's the problem

  • Jim get the phage nuke ready,were killing Ebola

    • datTweenlife, Ebola is a virus, not a bacterium

  • I’m allergic to antibiotics 🙁🙁🙁 If I take one I go to the hospital for a month

  • Why did I laugh so hard when he said *while they do commit genocide for breakfast...*

  • So puting the most deadleast thing in use won't harm use and it will save us? 😰😰😰

  • It's a hard knock life for bacteria

  • Nice worms reference. :P

  • Some forward this to the president ASAP

  • Can bacteriophage defeat gonnorhea

  • ty phages 💕

  • 1:12 genocide for breakfast

  • fungie?

  • WORMS 3D reference right there, the game that made me love parabolas.

  • But what if in the process phages will evolve to kill good bacteria? Cuz it won't have evolved protection against phages? Or, what if phages will evolve to invade human body cells? Then what?

  • Hope this is able to kill diseases like AIDS

  • But how is phages is the deadliest in earth? I mean how did the y become deadliest when they save lives?

  • No problem human cells are not affected by bacteriophage so it might good to use as a medicine and help many people.

  • MMM, genocide for breakfast.

  • 2:16 In the final step they produce Pacman boiii

  • Why did anyone even think about dislikeing this?? 1 they think kurzgesagt are lieing 2 they are paranoid 3 they are haters

  • So, they're kinda like rambos taking out giant monsters

    • Slimy Demon Why not. Aren't you Asian.... Oh wait

    • +Fire Power701 okay, never gonna use it then

    • Slimy Demon They must be genetically modified to kill the weeb inside people and then maybe it will be in full scale use

  • 5:03 thats some nice transformation animation


  • There were like no birds in the vid

  • Sadly enough I can’t even have penicillin because I’m allergic

  • steven universe reference?

  • Haven't russia been doing this for the last 50 years? Where we chose anti-bac, russia chose to focus more on phage's?

  • The bacteriapahges are like thanks snapping his fingers

  • Wait if we have an immunity to the deadliest being on the planet doesn’t that make *us* the deadliest being on the planet

  • Fuck it... Bacteriophage time

  • I see one problem with this, can the phages evolve to consume the most abundent cell once injected by which would be the human cell?

  • The problem is, I’m allergic to penicillin.

  • Save millions of lives even cancer? If you said yes I am gonna be a scientist to find a cure for cancer but... If you said no RIP DREAMS

  • Aren't those the things they use to make gems in SU?

  • if we do it right the infection killer wont kill us and we dont kill them sooo it could work out for us

  • Boop

  • And In a few thousand years they will be a part of our body and most like become a new type of blood cell...

  • You know, it's really refreshing to watch a US-tv video that's not some annoying guy screaming and filling people's heads with obvious lies.

  • 1:50 to 2:10 sounds a lot like sexual assault.

  • What about white blood cells?

  • 5:00 - 5:24 I wonder if there is a game like that.

  • (Bacteriophage [Phage] and Human Cell [Cell] meet) Phage: YOU CAN'T ESCAPE ME THIS TIME, YELLOW! (Continues chase on a fleeing Yellow Fever virus and bumps into Cell) Phage: Ohhhh, you've DONE it now! COME HERE BOY! Cell: No! Please! I never do anything wrong! (Cries) Phage: (Sniff) I'm sorry :( I didn't mean to upset you. Can I help? I can try to defend you. Cell: That guy over there wants to hurt me (Points to Ebola virus). Phage: Ok, hold on. (Phage charges at Ebola) Phage: BOI U BEEN BULLIEN MEH FRIEND WITH YO NAPPY ASS HAIRLINE? BOI IMMA BEAT YO GOOFY ASS SO HARD! BOI IMMA LAY MY FUCKIN CHILDREN IN YO MARSHMELLOW MAN LOOKIN ASS! COMERE WITH YO BALLZ FOR A CHIN LOOKIN SELF! Ebola: Yeah right, gay! You would never- (Phage inserts needle and injects the components of Bacteriophage into Ebola) Ebola: NOOOO! THIS IS NOT "DA WAE" I DIE! (Ebola bursts open and dies) Phage: Better now? Cell: Death, no death. Cell does not want to die, Cell will not die. Cell will not die today. Cell is forever free from age, Cell does not want to- Phage: Well say goodbye to our host. I'm leaving this organ. You can stay and get surgically removed, wierdo. Cell: CELL WILL NOT- (Lung gets removed right as Phage crosses to the next) Phage: Human Cells are so wierd. I'm not even gonna bother with them.

    • That was way longer than I thought. Im late on this video anyway.

  • a big fat yes

  • Very nice

  • Fages are cool

  • White blood cell "were completely serounded Stem cell" good by cruel world" Red blood cell "incoming phage strike" BOOM

  • When you overdose medicine 3:23

  • The bacteriophage looks like a robot.

  • Today's lesson on biology

  • We should love these little robot-like beings. They must be our new SUPERWEAPON!

  • Big pharma isn't interested in it because it cures. There's more money to be made in treating people for long periods of time. Bastards.

    • what a world we live in..

  • *phages grab weapons* bacteria:Oh no

  • This channel is awesome imma show this to my science teacher

  • I'm not a biologist or stuff like that but what would Happen it the Phage would turn against US and Attack Human cells because theres More of them inside us (that's Logical but nevermind)

  • Could this be the cure for Cancer tho?

  • The superman of nature

  • Wait.....I still don't get it

  • SO why dont funghi evolve to kill resistant bacteria?
