Nelson and her colleagues found that flu in pigs «follows long - distance swine movements from the southern U.S. to the Midwest,» with most of the human - origin H1N1 arriving at Midwest hog farms coming from the Southeast, and most of the swine - origin H1N2 coming from the south - central U.S. And that means the Midwest, as the final destination for many of these pigs, is «likely to provide a reservoir for multiple genetically distinct variants to co-circulate and exchange segments via re-assortment because of the continual importation of swine influenza viruses from other regions,» the researchers noted.

In addition to sequencing the woolly mammoth genome, Hendrik has reconstructed the diets of extinct giant sloths, debunked a hypothesis about the origin of human immunodeficiency virus (HIV) and sequenced the genome of the bacterium that caused Black Death.

Researchers have identified the evolutionary origins of human herpes simplex virus (HSV)-1 and -2, reporting that the former infected hominids before their evolutionary split from chimpanzees 6 million years ago while the latter jumped from ancient chimpanzees to ancestors of modern humans — Homo erectus — approximately 1.6 million years ago.

Researchers at the University of California, San Diego School of Medicine have identified the evolutionary origins of human herpes simplex virus (HSV)-1 and -2, reporting that the former infected hominids before their evolutionary split from chimpanzees 6 million years ago while the latter jumped from ancient chimpanzees to ancestors of modern humans — Homo erectus — approximately 1.6 million years ago.

A new study has found that a novel avian - origin H7N9 influenza A virus, which has recently emerged in humans, attaches moderately or abundantly to the epithelium of both the upper and lower respiratory tracts.

All influenza viruses ultimately come from birds, and the paper begins the somewhat operatic and knotty story of this outbreak's origins with an H1N1 first isolated in swine in 1930, which itself was a close relative of the virus that caused the 1918 pandemic in humans.

As these were the first pigs ever found to harbor the virus, this obviously raises the possibility that they infected humans and played a role in the origin of the outbreak.

Researchers are trying to pin down the origins of both HIVs to understand how often new human viruses emerge.

A new analysis showed that the genes of the deadly 1918 pandemic are of avian origin, not from the mixing of human and swine viruses

After painstakingly piecing together the genome of the extinct strain, a team led by virologist Jeffery Taubenberger, then at the Armed Forces Institute of Pathology in Washington, D.C., concluded in 2005 that the virus most closely resembled viruses of avian origin; the team suggested it had become transmissible between humans after a couple of key changes (Science, 7 October 2005, p. 28).

By solving the origins and the reassortments that led to the 2009 A / H1N1 pandemic, researchers might be able to study existing «brothers and sisters» of the virus to understand the type of mutations needed to allow a virus to jump into humans.

In fact, plenty of «our» DNA has foreign origins — from extinct early humans to viruses — and can have both good and bad effects on health.

CDC researchers took ferrets never infected with an influenza virus and injected them with this year's vaccine, which has an H1N1 component of human, not swine, origin.

The fact that some viruses that infect humans share structural features with viruses that infect bacteria could mean that all of these viruses have a common origin, dating back several billion years.
