You know, the problem is if this virus occasionally mutates so dramatically, it essentially is a new virus and then we get a pandemic.

And what we've been able to do is engineer a virus to basically take dye absorbing molecules and line them up on the surface of the virus so it acts as an antenna, and you get an energy transfer across the virus.

But by the time you get to block nine, you see that respiratory syncytial virus.

H7N9 is a bird flu strain of the species Influenza virus A (avian influenza virus or bird flu virus).

A virus has either a DNA or an RNA genome and is called a DNA virus or an RNA virus, respectively.

The Japanese encephalitis virus is a virus from the family Flaviviridae.

The four are Bundibugyo virus (BDBV), Sudan virus (SUDV), Taï Forest virus (TAFV) and one simply called Ebola virus (EBOV, formerly Zaire Ebola virus).

H10N7 is a subtype of the species Influenza A virus (sometimes called bird flu virus).

And a pig disease, a pig virus, and a human virus can both proliferate, and because of their kind of reproduction, they can combine and produce a new virus.

Maybe he ate something bad for lunch, and then things get really horrible, as his skin rips apart, and he sees a virus coming out from his insides.

And so we use a virus that's a non toxic virus called M13 bacteriophage that's job is to infect bacteria.

Virus protection and virus development constitute an uneven arms race.

Rinderpest, which is caused by a virus closely related to measles virus, is a disease of cattle known since Roman times.

She passes that virus on to baby, and it takes a really, really, really long time as the redwood trees for that serious meme to get out of our operating system.

Clearly the bottom line is the virus eventually attenuates, and ceases to be a lethal virus to humanity, and finds other hosts.

A viral protein is a protein encoded by a virus genome.

An oncovirus is a virus that can cause cancer.

So one part of the virus grabs a carbon nanotube.

And so through a process of selection evolution, we went from being able to have a virus that made a crummy battery to a virus that made a good battery to a virus that made a record breaking, high powered battery that's all made at room temperature, basically at the bench top.

Influenza A virus subtype H5N1, also known as A(H5N1) or simply H5N1, is a subtype of the influenza A virus which can cause illness in humans and many other animal species.

Now, by the time we get out here to, let's say, acute bee paralysis virus probably a bad one to have if you're a bee this virus shares almost no similarity to coxsackievirus, but I can guarantee you that the sequences that are most conserved among these viruses on the right hand of the screen are in identical regions right up here.

Another consideration is that different strains of a herpes virus can have different characteristics which may result in differences in the precise effects of the virus.

Here's the latest virus we've found, in a file called Server.exe.

And so we're getting unique signatures, a fingerprint for each virus.

Once within a muscle or nerve cell, the virus undergoes replication.

H3N1 is a subtype of the species Influenza A virus, mostly affecting pigs.

Ebola virus under an electron microscope.

Smallpox Smallpox is a highly contagious disease caused by the Variola virus.

Some cases have been misdiagnosed as having been caused by a virus.

This was not the first synthetic virus a polio virus had been made a year before but it was only one ten thousandth as active and it took three years to do.

For those of you who aren't familiar with memetics, a meme has been defined as an idea that replicates in the human brain and moves from brain to brain like a virus, much like a virus. The way a virus works is it can infect and do the most damage to someone who has a compromised immune system.

A virus can be just a couple hundred lines of computer code, compared to hundreds of thousands of lines for anti virus programs, which must be designed to detect wide classes of enemies.

They got a shot of virus up the nose, let's see what happens.

It is caused by a DNA poxvirus called the molluscum contagiosum virus (MCV).

Weakened by the virus, the plants turned out to be a poor investment.

AIDS was discovered 1981 the virus, 1983.

The virus then buds from the cell.

One example is the West Nile Virus.

The natural hosts of the Japanese encephalitis virus are birds, not humans, and many believe the virus will therefore never be completely eliminated.

It's like, as many times as the virus changes its clothes, it's still wearing the same socks, and now our job is to make sure we get the body to really hate those socks.

Viruses are parasites to cells, and each virus attacks a particular type of cell.

Our first task was a 5,000 letter code bacteriophage, a virus that attacks only E. coli.

For example, a flu strain is a certain biological form of the influenza or flu virus.

And the idea is that we simply have virtual patterns, because we're never going to get samples of every virus it would be virtually impossible. But we can get virtual patterns, and compare them to our observed result which is a very complex mixture and come up with some sort of score of how likely it is this is a rhinovirus or something.

But even a mild influenza virus kills a lot of people, especially those with other medical problems.
