T4 Virus infecting a bacteria.

[ohedd]

That was what we looked at when trying to figure out how to land on the moon!

[GordonFleaman]

It drills right through the cell wall if I am correct.

[AppleHead12341]

this looks so painful

[Weraisethenerdyflag]

You think these things are small? You should see Earth compared to a galaxy!

[Frisbieinstein]

BacteriUM.

[PrideOfGroningen]

robot.

[waheyforgavin]

looks like one of those drills the machines send to zion in the matrix revisited :o

[7ito1990]

IT'S THE T-VIRUS! RUUUUUUUUUUN (actually, should I? I gotta ask X'D)

[Thegoodlol]

@Normalismagistralis thank you

[EltBerserker]

i can fap to this

[AiRsTriKeITA]

@EltBerserker O_O

[MrC0MPUT3R]

Huston this is T4. The colonization process has started.

[judohid]

is this animated exacly how it happens ? facinating

[Jasperschaap]

@judohid Well first of all the virion itself does not move. Secondly these things are so small that they don't have a color. But overall it gives a nice impression. ;-)

[URProductions]

@Jasperschaap How can something be so small that it doesn't have a colour? Is it because the virus is smaller than the actual wavelengths?

[0neTwoTree]

@URProductions Yes.

[tingmarco1]

this type of virus is bacteriophage

[NevsterPhoenix626]

@Thegoodlol

The T4 virus was a naturally found virus that infects bacteria. It injects its DNA into the bacteria and produces copies of itself which eventually rupture the bacteria and kill it. Nowadays scientists use the T4 virus to inject bacteria with new genes, so that they don't due, but can produce things like human insulin for diabetics. Any help?

[Thegoodlol]

is this t4 virus made by humans just to infect poor e-coli ? please educate me i'm very stupid, also, what happens after e.coli is infected? does it die immediately?

[CCkeminliu959]

The virus looks like a spider.

[Justas923]

I consider this to be beyond epic

[AlbertWeskerfan100]

the charactaristics of a living thing is: respond to change (it moves) has DNA, it reproduces, it takes in and uses energy, and has cells, which you can see in the video so is it living or not??

[jakubgt1]

@AlbertWeskerfan100

You really need to take some microbio-101. Bacteriophage do not move and have no option for any form of motility. The attachment to the host is all by chance and completely random. Viruses don't use any energy and even if it did, the virus would not be able to utilize the energy as they are obligate intracelluar parasites. Viruses don't have cells either.. its made up of two components (nucleic acids and a capsid).

[AlbertWeskerfan100]

@jakubgt1 Well i want to be a Stem Cell Reasearcher when i go to college but I havent finished school yet. I havent got the option to take micro-biology to study viruses and bacteria. So thank you for informing me of that.

[NorthForkFisherman]

@AlbertWeskerfan100 The movement comes from the interactions of the various surfaces glycoproteins and the proteins that make up the virus coat. It's waht's known as an allosteric protein. The interatomic forces cause the virus parts to change shape and inject the DNA package thru the cell membrane. Then the phage starts to get down by reproducing itself. BTW, molecular biologists use phages like this to manipulate DNA in cells.

[ArmyRangerish]

viruses are not living: it has a fuckin mouth and eyes lawl

nah but seriousy that is one badass loking virus

[xUK91x]

Viruses are nanotechnology, there has never been any reason for nature to introduce 'viruses' while everything else has a purpose of some kind. It may or may not be human made...

[gabbergandalf667]

@xUK91x

Are you kidding me? Surely you do know that there are ten times as many virus particles in the biosphere of the earth then there are cellular organisms, and there being a variety that we can't even begin to understand. Way to make this, during roughly a hundred years that we know of viri.

Besides, nature has no reason to do anything. It's just evolution, it happens without purpose.

[xUK91x]

@gabbergandalf667 you do realise it was a joke dont you?

[gabbergandalf667]

@xUK91x

oops, my bad. to many freaks in this comment section.

[solisvictor1991]

I believe the reason a virus can be so simple is because it does not have to build a network of defense mechanisms simply because it so small,no competition from smaller creatures that want to invade and eat it from the inside,hence the extreme simplicity of its design.

[JasonBrazen]

I don't understand. Things like bacterium and viruses are not sentient. How does it seem as if they "know" what they're doing! Scary.

[gabbergandalf667]

@JasonBrazen

It's a beautiful example of billion years of evolution

[tingyuyan12]

looks like a nanobot :D

[MonicaKn17]

Jokes aside, is this part of a larger series? I'd love to watch the whole thing.

[MonicaKn17]

RAPE!

[8900609]

Bacteriophage caught my attention because they do look like nanobots :D

[hansho13]

me and my friends refer to this as "the teabag virus"

[FiveStarsPerShoulder]

Germ porn



[mortalkombat8001]

viruses looks like machines =D

[burgershot10]

I'm gonna make my own animation. :)

[Zanmatt2g]

why are the most badass things in nature so freakin tiny??

[zaaz369]

yo dawg i heard you like rna, so i put some rna in your dna so you can copy while you copy

[HackersSun]

how.. the..?

IT HAS A DRILL. A FREAKING DRILL!

How the hell can this thing not be alive!?!? Biology... you're one SCARY thing.

Its true; fact is stranger then fiction..

Now I'm scared..WONDERFUL.

[GeorgeL909]

@tahir7320 In short, the tail fibers bind the receptors, the tail pins help create a hole, and the helical sheath contracts to release the DNA into the cytoplasm.

[GeorgeL909]

@tahir7320 As far as I know T4 attaches first with the tail fibers ineracting with the polysaccharides of the outer layer of gram- cell envelopes. Then the tail fibers retract, and the out comes the core of the tails, which are the really fine tail pins. They poke a hole in the peptidoglycan layer with some kind of enzyme that's like lysozyme, and then the tail sheath contracts, passing the viral genetic material through the hole.

[linman888]

ow that must hurt cuz it looks paint full @ 0:33

[neverendingscotty]

Now I know where the T4 Project got their name and symbol :) Great band, check them out!

[sahaja007]

is this at human body???

[lolicatluver]

@sahaja007 bacteria phage infect bacteria, so likely this takes place in a human host, or it could be in another host. I believe this bacteria phage only infects E. coli bacterial cells! cool huh?

[Budgieification]

@sahaja007 theres no way to know. its a bacteriophage so its infecting a bacterial cell, not human cells

[dbrooks12009]

viruses are like robbots, programed to insert its RNA into cells.

[zerafix666]

t4 virus is the most awesome living (undead? who knows! lol) thing ever. when i saw it for the first time on my schoolbook, i couldn't believe it was real. just look at how awesome that thing is!

[The420KushKing420]

@zerafix666 dude i am thinking the SAME exact thing! it so weird and creepy (the pointy legs --->archnaphobia D:) But besides that its my favorite nonliving uhh thing?? XD i mean its amazing how they have no brain, no nothing! just limbs and it just floats around infecting stuff, i love it :DD!! (wouldn't like on in me just saying)

[PortillaJ22]

...Was I the only one who once thought as a little kid that a bacteriophage was a small, robotic, sentient being?

Still, it's a very interesting thing, in my opinion: Something injects its own DNA into a bacterial cell to reproduce itself [?].

[CEURO2]

ok. it is very beautiful. hello everyone.

[ExtremeWelder]

So bacterias got mosquitos too. This day ain't wasted; I learnt something new.

[MrGodismysavior]

@ExtremeWelder Actually, what this virus did was insert it's RNA into this cell so it could reproduce and it had to get inside the coating of the cell. It will soon produce little baby viruses until the cell gets so full it bursts the cell and after that happens the babies go and find another cell.

[ExtremeWelder]

@MrGodismysavior Yes I know. But I just thought it was funny the process looked so much like a mosquito biting.

[mercanaries3]

what the hell does this thing do anyways??

[NinjaYoyos]

jizzed in the cell

[jakemeow]

WTF? When Im sick, they are drilling my brains?

[rockkong1]

@jakemeow Yep you should thank the freaky basterds

[jakemeow]

@rockkong1 :D

[Pilkingtube]

@jakemeow No, you're not a bacteria. Besides, take comfort in knowing that while you're fighting these things, your body is literally eating them alive, tearing them apart and generally raping these things.

[jakemeow]

@Pilkingtube ew

[ninjax261]

@jakemeow no... they only kill bacteria... hence the term 'Bacteriophage'

[spyfox0001]

Should be: "...infects a bacterium."

[menu12345]

looks like some Nanotechnology left by aliens or something

[grarg12345]

imagine this happens to your cells almost every day

[TheCoffeeNut711]

so bacteriaphags take a shit inside a bacteria. maybe their not so different form us.

[jhmoonman]

Thanks fir the info!

[RedCodeStudios]

its giving its mom aids! LOL

[Flem1337]

What is alive? We may discredit viruses as being alive, but theres nothing to stop them from being remnents from the origin of life itself, only simplified in time and lost their ability to reproduce and metabolise energy in exchange for having to transport the bare minimum of genetic material needed for the only reason of life.

And that reason is: Survival

[Chaos1999man]

this video freak me out a little bit

[MrEVILmodZZ]

Alien mini space ships looks like one and the way it works makes it look like technology stuff.

[neouberx]

nanotechnology created by the watchers to control population.

[DangerClose2KX]

God I have to do a fucking progect on this in skool I don't even know what the hell the symtoms are

[fairhillnorrie]

isnt like a probe landing on Mars??? maybe, just maybe Aliens can only see us through a microscope..... just a thought...

[Aev308]

Can some one please explain why in some videos and pictures the virus is a hairy blob and in some it has legs and mechanical movements. The blobs get sucked in by a cell and the legged ones inject the dna like a blood sucking insect?

[jhmoonman]

O:21. n Joeidsouza2. L. O. L. Right on!! Y doesn't some one talk about what's happening? Is it for real or just some type of art?

[LadySpyogenes]

@jhmoonman

If you're asking if what's being shown in the vid is real, it is. It's not actual footage of what's happening, but a computerized reconstruction of the real deal. This is more or less the way a bacteriophage would latch onto a bacterium and inject its genetic material into the cell.

[UItimatesnake]

0:21

we just landed on mars guys

[ttopperr]

@UItimatesnake No, We landed inside some ones computer.

[joeldsouza2]

spider man 5

[thratstakin]

I did not know that the virus looked like a dildo.

[MetanaboI]

Its allien nanotechnologies with biological material... Its one fact destroing GOD!!!!!!!!!!!!!!!!!!! FUCK YOUUUUUUUUUUUUUUUU!

[PrinttScreen]

wat

[kei1010101010]

Such complex biological physics, i wonder how...?

[sandeshpaudel]

that virus sure looks like some kind of a robot. is it possible that they are nano technology from aliens?

[12monkkeys]

It is truly hard to comprehend that the T4 virus is not alive.

For something so "dead", it sure executes many complex movements... to say nothing of appearing to have an almost underlying intelligence.

Thank you for this upload.

[huntpivot2]

@12monkkeys

Then again, a mechanical clock isn't "alive," yet it still preforms extremely complex and fine movements, or even your computer.

Thank you for this comment.

[hoyt596]

@12monkkeys it's not dead or alive, it's like a material that replicates by changing other (living)material into itself, which sort of looks like it's reproducing like a living creature. Crystals can grow and if you chip off a piece it can also grow, but they aren't alive.

Obviously is isn't intelligent because it's so ridiculously small that it doesn't have enough molecules to form into any kind of thinking mechanism.

Also, they don't fit the definition for a living thing.

[MEareCAT]

@12monkkeys Where you a goody-goody teachers pet at school? :L

[12monkkeys]

@MEareCAT <-- Sadly another 13yr old YouTube punk, trolling the comment section for attention. Grow up.

Next time, before making an ass out of yourself, plead with your 7th grade teacher to once again school you in the proper use of "where", "were" & "we're".... tell her you’re desperate to appear smart & witty on YT because of how alone you are in the real world; she might take pity (as I have with you) and help you out.

Good luck friend.

[apon91]

@12monkkeys the use of where, were & we're in ones text does not make the person

[neferiusnexus]

@MEareCAT Actually, I found your attempt of making a rational supposition on the subject a few hundred times more mature than several dozen other comments I've come across on YouTube.

I think the main reason people hated on you was your username more than anything else.

[MonsuerLePlague]

@12monkkeys The same could be said about every complex machine we humans use. The only notable difference being the origin of said machine.

[panther2598]

@12monkkeys Agreed, I'm starting to wonder whether or not viruses have a conscience.

[SCRulerShinoda]

@panther2598 They're purely molecular automatons. Simple as that. It's a mindless killer. However, we need Bacteriophages.

[panther2598]

@SCRulerShinoda I know, but they're so complex with their movements. It seems like they're alive.

[SCRulerShinoda]

@panther2598 I'm full aware of the human tendency to ascribe animistic motives behind complex things.

[AbtinX]

@12monkkeys It's closer to living death, a zombie organism :D

[BioFizz]

@12monkkeys well, one must consider that the concept of "life" and the qualifications that something must have in order to be deemed "alive" is a man made concept. lets just say that the T4 virus is half-alive :D

[keenanzona]

@12monkkeys Yeah I wouldn't call it "dead" either, more like inert, but you get the idea.

[rollinthunder1000]

@keenanzona

i dont how the hell can it be dead

im so confused can u bring it to light or sumthin this is just retarded

o wait you called it inert....fuck it i still dun get it

[Digiscat]

@12monkkeys The bacteria say the same thing about our guns. So many complicated movements just to launch a block of cells called metal, fascinating. End joke.

[Aff01000001]

@12monkkeys

Yeah, I know what you mean. Even though the biological concept of 'life' does not apply, I can't help but think that there's something else in there..

[neferiusnexus]

@12monkkeys Well you seem to have forgotten that this was in fact a CGI animation

In reality that thing is so small it doesn't even have color, the same way atoms under an electron-microscope and pictures of supernovae and spiral-galaxies taken from a space-telescope are photoshopped afterwards with custom colors that supposedly represent the nature of their composing elements (green for Chlorine, yellow for Sulfur etc.)

But this isn't even that!

Any movement you see is purely computer-generated

[coltoniverson]

1.attach

2.invade

3.copy

4.release

[chickenbuttforu]

It reproduces by injecting its DNA into the ribosome so it will make more viruses. Then the bacteria cell will pop with viruses.

[rhcprule3]

They are Robits!

[SirTannen]

This reminds me of star wars, except with more explosions.

[imalmostdone]

I'm pretty sure these are space aliens. Just weeelittle.

[bighead996]

viruses arent a living organism thats why you cant kill them with antibiotics

[darkangelcloud7]

They seem like micro insects o__o

[SlimAgnus]

Interesting animation, but I don't expect a virus to have little hooks with which it can grab onty a bacteria, nor do I expect it to look like something from a sci-fi movie. A little sound would also have improved the animation.

[broncosvspatriots]

@SlimAgnus It does have little hooks. The hooks 'anchors' the virus onto the bacterium. Genetic material is then squarted into the bacterium. This genetic material takes over the cell, and begins to assemble new viruses. Eventually, there will be so many viruses that the cell bursts open, killing the bacterium and releasing many new viruses. Basically, everything you say actually takes place.

[moneyjr1122]

it doesnt even look like a cell, it looks like a machine

[ImGoingToBeAnMD]

@moneyjr1122 Viruses aren't made up of cells, they are made up of a strand of hereditary material, which is surrounded by a protein coating. This is one of the reasons why we're not sure if we should classify them as living or nonliving. If we classify them as living, then one part of the Cell Theory will be proven wrong. This would be the part saying that every organism is made up of a cell or cells.

[moneyjr1122]

@ImGoingToBeAnMD i never said they where made up from cells I'm aware they are just proteins and they do not carry the essential atoms to be consider living so that's why they are not they basically are just machines with a blue print

[ImGoingToBeAnMD]

@moneyjr1122 Sorry, I was mistaken when you wrote, "It doesn't even look like a cell..."

[moneyjr1122]

@ImGoingToBeAnMD no props but serious what are the purpose of cells are they like proteins that didn't function right so our body got ride of them i know some of them are man made but what about the ones that are not

[uberari]

@ImGoingToBeAnMD it isnt even a cell! its protein with dna!

[Cmann600]

its really creepy how that virus looks and acts like some sort of machine.

[skewer45]

Especially considering the fact that it's made up of only a few million atoms, if I remember correctly...

[CuppaS00p]

Viruses can't really move on their own. They just drift along, and once they land on something, they encode their DNA into whatever cell they landed on

[serdarguy12]

BACTERIA!You dont see them!But they are there!

[blackout1148]

this virus is actually very good:) because mr T4 infects bad bacteria like e-coli therefore saving human lives:D

[Sonicku]

EWW PERASITES!! its that what the flu is??

[SolidGaby]

yes

[Floyd13778]

Hah, I KNEW these things "looked" like some kind of insect, disgusting! But very interesting, too, how did they do this? It's actually "just" a computer simulation, isn't it?

[33Bubblewrap]

The virus injects its DNA into the bacteria, it basically just takes over all the cell's functions. The cell starts to create all the virus' proteins and genetic material which assembles into new viruses. Then there are too many viruses that the cell bursts open and the viruses flee out of it. Damn little bastards. Hahaha.

[supermario1299]

its injecting its DNA into the cell and since the cell has to do wat ever the DNA tells it to do. the cell makes more and more cells then eventually creating millions of the same harmful DNA. thats how the T4 works and how you get sick.

[xxmetioqurexx]

32. gave 13 year olds a boner

[stinkysnak7]

hahahah

[aloysiaweber1]

T4 bacteriophages are soo cool looking. I want to have an artist custom-make me some bacteriophage earrings. Viruses are rockin' the geometric look.

[33Bubblewrap]

Bacteriophages look like little space ships, huh?

[Judicial78]

@33Bubblewrap Maybe we made spaceships look like bacteriophages.

[k0p4n]

@33Bubblewrap lol more like the space ships look like the little bacteriophages haha

[Suckassloser]

@33Bubblewrap The intelligent contribution of your average youtube community member =P

(Please don't take this the wrong way!)

[LBPFan65]

@33Bubblewrap  not bacteria

[Budgieification]

@LBPFan65 thats the type of virus retard.

[jor1116]

0:32 PENETRATION

[kurt05051987]

Awesome...!!!

[imwustrau1]

omg it just drilled a hole and pooped in it wtf

[nlty2000]

omg

drilling for oil

[tabitgibs]

tat is really how a viris attacks cells it just dont happen like tat

[musztafamsn]

this is fake...

[WorldDisasterStudios]

dat thing just gave me arachnophobia.......

now i fear spiderman.... eww...

[zulnasir97]

wow must be alot of money spending virus type microscope

[nipunn12]

scary

[MiNiMaLsAnItY]

Were those dyenin/kinesin motor proteins which helped in the injection process?

[DeeJayRhythmOne]

looks worse than an alien

[LBJohn15]

danm thats creepy lol not trying to be retarded but that kinda looks like the spider robot thingy from the matrix the one that holds all the babies and shit lol

[WorldDisasterStudios]

u speak the truth....

[streetstylesk8er]

how would you get those things in your body???

[xoxoRiverTamxoxo]

@streetstylesk8er:

If a person infected with a virus (eg. the common cold virus) sneezes on you, you can contract the virus by getting their saliva (which contains the virus) in you're mouth (maybe they sneeze on you're food which you go on to eat, or on you hand which you touch you're food with, or even directly into you're mouth). The AIDS virus can even be tranfered through blood (so if you get the blood of someone with AIDS on you, you can get it), or through semen during sex.

:)

[streetstylesk8er]

@xoxoRiverTamxoxo OH THANKS!!

[Simon6663]

@xoxoRiverTamxoxo thats not correct, you cannot get aids by coming in contact with someones blood, it must enter your body, if you get it on your hands you won't get infected

[mermaidstars123123]

yeah even more dangerous when you get

it on your hand SKIN IS LIKE TISSUE!!!!

And it will go in you blood stream until you have WHITE BLOOD cells in your body!!! Sorry if its like i'm shouting to you.

[Simon6663]

dude basic bio teaches that skin is a layer of dead cells that acts as a physical barrier to the surroundings.

[streetstylesk8er]

wait so are these things good or bad??lol i'm a retard

[LupusFang]

T4?

Well, like E. Coli, I think they could be both.

If they're killing E. Coli in its good forum, they're bad. And vice versa.

[VyoletWillohw]

No, they inject their DNA in your cells which makes like three more viruses come out

[streetstylesk8er]

so they're bad????

[ghoang]

So i guess it's like "Aliens" on a cellular level.

[xoxoRiverTamxoxo]

@streetstylesk8er:

You are not! D:

They are bad. They reproduce by destroying cells the cell which hosts them (eg. our cells!), which makes us sick (people say you can't live without love, but cells are even more important). So they are bad. "Pathogenic" is the official term.

:)

[girtv]

actually, bacteriophage are beneficial to health, because the can target germ cells and neutralize them before we get sick

[AnonymousCracker]

It yiffed it

[OMGaRETARD]

is that what those viruses really look like?

[anniehorselover]

Yup! It sure is!

[TeslaKuhn]

don't you just love the geometric patterns

[MisssNickjonas4EvEr]

haha why does it look like a space movie!!!

[XxDeathExpiredxX]

I love how these YouTube videos are about Viruses and we're talking about religion. LOL.

...Well it does sort of relate to this. Being that this is science and you are all contrasting and comparing it to religion.

On my own note : Bacteriophages are so cute :D [Yeah I'm weird.. xD]
