A strain of the influenza virus that kills people with weakened immune systems may wipe out other strains that cause the flu, a new study suggests.
The researchers say the new findings add to the growing evidence that the flu is a complex disease, and they suggest that the current strains of the virus that kill people with compromised immune systems have already begun to disappear.
The finding comes from a new virus strain that has not yet been identified, and it comes at a time when experts are increasingly worried about how the pandemic could affect people with weak immune systems.
Researchers say the strain, dubbed “B4-B5” by researchers, is highly efficient at killing viruses that are present in the body, and the new strain is able to kill them too.
The new strain, called “B5-B6,” is less efficient at eliminating the virus in its current form, and is less effective at eliminating other viruses.
This is a major advance because it’s the first time we’ve seen a strain of influenza virus to actually wipe out viruses that infect people with strong immune systems, says David Pappas, a scientist at the National Institute of Allergy and Infectious Diseases in Bethesda, Maryland.
It’s the sort of thing we want to know more about, he says.
It’s also an important finding because, until now, there had been little research to show how viruses like B4-E2 and B4s B5 and B6 were able to wipe out each other.
Previous research has suggested that viruses like these were able and could even wipe out the strains of viruses that normally infect people.
But the new research shows that they’re not.
The new strain of viruses can be lethal to the other strains of influenza, as well.
They can also kill people who have weakened immune system because the virus does not kill cells that normally produce antibodies to the virus, and this is a significant loss of immunity, says study author James E. Miller, a professor of microbiology at the University of Alabama in Huntsville.
The study was published in the journal PLoS Pathogens.
It was funded by the National Institutes of Health.
The team’s study looked at how B4 and B5 viruses were able with a new strain to kill the virus they normally infect, and found that the B5 virus was also able to survive the virus.
The B5-E3 strain of B4 is more effective at killing virus B5, but it has less effect against virus B6, which has more ability to kill viruses.
The B4 virus has been associated with more severe infections than the B6 virus, but this is the first study to show that the viruses kill the other two strains of virus equally well, according to Miller.
“I think this is an important step toward identifying the viruses and the strains that we’re most likely to be able to find and wipe out,” Miller says.
This study is one of the first studies to look at the viral components of a new pandemic virus, so it’s important that we understand the mechanism of how this virus is able and kills viruses, he adds.
But more research is needed to figure out how the B4 strain is effective against the B7 strain of flu.
The other key finding of the study is that the new strains are able to eliminate the viruses B4, B6 and B7 as well, and not just B5.
That suggests that the two strains might not be identical, and that they may differ in their ability to knock out other viruses, the researchers say.
This type of research is important, because if we can learn more about how viruses kill each other, we can make more accurate predictions about the flu.
We can better predict when we should be concerned about infection with a specific strain, and how to avoid it.
The virus researchers say that future studies are needed to better understand the mechanisms of the viruses.
We want to understand how these viruses are able and why they can kill each another, and what they’re capable of.
We also want to study the effects of the pandemics virus on different populations, which is what we need to know to determine if they’re going to continue to spread and be as dangerous as they are today, Miller says, adding that future research could also look at how the virus affects the body in the long term.
The pandemic has already claimed more than 2.5 million lives worldwide, with more than 30,000 deaths in the United States alone.
This is one more strain of pandemic that could cause an even greater number of deaths, and many are worried about the virus’s impact on the health of people around the world.
