    HIV lineage confirmed to be from chimps, peta can't argue chimp testing now.

    HIV's ancestry traced to wild chimps By LAURAN NEERGAARD, AP Medical Writer
    55 minutes ago



    WASHINGTON - Twenty-five years after the first AIDS cases emerged, scientists have confirmed that the HIV virus plaguing humans really did originate in wild chimpanzees, in a corner of Cameroon.

    Solving the mystery of HIV's ancestry was dirty work. Scientists employed trackers to plunge through dense jungle and collect the fresh feces of wild apes more than 1,300 samples in all.

    Before that, it took seven years of research just to develop the testing methods to genetically trace the primate version of the virus in living wild chimps without hurting the endangered species.

    Until now, "no one was able to look. No one had the tools," said Dr. Beatrice Hahn of the University of Alabama at Birmingham. She led the team of international researchers that reported the success in Friday's edition of the journal Science.

    "We're 25 years into this pandemic," Hahn said. "We don't have a cure. We don't have a vaccine. But we know where it came from. At least we can make a check mark on one of those."

    Scientists long have known that nonhuman primates carry their own version of the AIDS virus, called SIV or simian immunodeficiency virus. But with one exception, it had been found only in captive chimpanzees, particularly a subspecies that in the wild populates mostly West Africa.

    It was not known how prevalent the virus was in chimps in the wild, or how genetically or geographically diverse it was, complicating efforts to pin down the jump from animal to man.

    Hahn's team tested chimp feces for SIV antibodies, finding them in a subspecies called Pan troglodytes troglodytes in southern Cameroon.

    Chimps tend to form geographically distinct communities. By genetically analyzing the feces, researchers could trace individual infected chimps. The team found some chimp communities with infection rates as high as 35 percent, while others had no infection at all.

    Every single infected chimp had a common base genetic pattern that indicated a common ancestor, Hahn said.

    There are three types of HIV-1, the strain of the human virus responsible for most of the worldwide epidemic. Genetic analysis let Hahn identify chimp communities near Cameroon's Sanaga River whose viral strains are most closely related to the most common of those HIV-1 subtypes.

    "The genetic similarity was striking," Hahn said.

    The first human known to be infected with HIV was a man from Kinshasa in the nearby country of Congo who had his blood stored in 1959 as part of a medical study, decades before scientists knew the AIDS virus existed.

    Presumably, someone in rural Cameroon was bitten by a chimp or was cut while butchering one and became infected with the ape virus. That person passed it to someone else.

    The Sanaga River long has been a commercial waterway, for transporting hardwood, ivory and other items to more urban areas. Eventually, someone infected made it to Kinshasa.

    "How many different transmission events occurred between that initial hunter and this virus making it to Kinshasa, I don't know. It could have been one, it could have been 10, it could have been 100," Hahn said. "Eventually, it ended up in an urban area, and that's where it really got going."

    Somewhere in all that spread, the virus became more deadly to people than it is to chimps, who seldom are bothered much by SIV.

    The research seems to settle any question of HIV's origin, said Dr. Anthony Fauci, the National Institutes of Health's AIDS chief.

    When tracing a virus' evolution, "it's important to get as close to the source as you can," he said. "It's of historic interest."

    Incidently, anyone see that Dave Chapelle stand-up where he talks about this?

    I thought that was common knowledge.

    More importantly, how old is this lineage, and where are the certificates?

    The certificates and secret scrolls are hidden in a sacred cave deep in the Congo.

    See, the chimps are teh d34dl3y. I always knew chimp-fucking would come back to haunt us!!! I knew, I just fucking knew!!!!

    The street argument is retarded. BJJ is so much overkill for the street that its ridiculous. Unless you're the idiot that picks a fight with the high school wrestling team, barring knife or gun play, the opponent shouldn't make it past double leg + ground and pound - Osiris

    it's always been assumed, and seen as the most likely answer (conspiracies aside). this is the first empirical proof.
    I think.

    I'm sure the guy I work with who has been HIV positive for the last 20 years will feel better knowing the virus's origin for certain, that was always his primary concern...

    It does help since now virologists know with 100% certainty where it comes from. A cure won't come off a lab from blind mixing of herbs and concotions. Anything in the way of better understanding the evolution of the HIV virus is a welcomed thing.
