Wild chimpanzees who find the closest human's HIV

AIDS, this virus in 1959, the first discovered, in the subsequent half century, it quickly spread worldwide.

The origin of AIDS, there are various is the African Green monkeys came, as polio vaccine cause, and even had some reports that are from the cold war superpowers of biological laboratory leak out, but most of the scientific research was launched around Africa's apes. Recent science magazine published a discovery, scientists said in wild chimpanzees who discovered similar human AIDS HIV by a virus, this more confirmed HIV originated in chimpanzees.

Orangutans last seen HIV: human AIDS

This finding simply, scientist in southern Cameroon jungle, found in wild chimpanzees who also SIV virus, an HIV-infected HIV closest, but prior to this, the scientists at the Zoo Gorilla was found SIV virus.

It is often said of the HIV virus (acquired immune deficiency syndrome) is the cause of AIDS (AIDS) in the HIV virus, H is the English acronym for "human", while SIV virus (APE immune deficiency virus) is generally considered the predecessor of the HIV virus, SIV of S is the English acronym for "Primates".

The virus of contact is scientists have long suspected that AIDS from gorillas, but prior to this, people of evidence limited to captive gorilla.

The discovery of orangutan HIV and human HIV subtypes of O is very close, which is the scientific community for the first time in Gorilla Group found such a virus.

So far, scientists have found that more than 30 kinds of African primates carrying different species of apes AIDS virus.

Participate in the study of Peeters, media interviews, said that they are in the southern regions from Cameroon collected hundreds of primates for testing of faeces, accidentally in six Gorilla droppings

were found in the human immunodeficiency virus HIV-1 antibodies. The ensuing gene analysis found that gorilla for HIV and HIV subtypes of O.

In HIV, there are three subtypes, M-, N-type and-O.

The most common is M subtypes, the latter two are very rare, so far only 12 cases of N-type symptoms found in Cameroon, scientists believe that these two are chimpanzees by blood for humans. While o-are also rare, and only partially present in Cameroon, Gabon and near other African countries, but in that time, scientists are still unclear O subtype.

This discovery was published in mid-November in science magazine, is the last may similarly published in science magazine's continued on discovery.

Seeking the secrets of chimpanzees is safe

Previous research indicates that Gorilla genes of HIV may 100 million years ago already exists, its related monkey virus variant transmission Gorilla, the researchers speculate until 1930, the Central African region of the people began to hunt and hunt orangutan, therefore being transmitted, this raises the widest spread out worldwide popular virus HIV-1 model, while another HIV HIV-2 is confined to West Africa, scientists speculate that because of the 1960s people eat monkey meat.

The source of HIV is more critical, Gorilla while many come with Gorilla HIV, but did not like human-like lesions of occurrence of such a scale.

"We ultimately want to know why the HIV virus in humans is so widely popular, but in the early infection baboons who has cancer?" expedition team leader of the United States, University of Birmingham, said Professor Hann.

History of HIV found that:

Figure for AIDS (HIV).

1.1959 years of Republic of the Congo, now an adult male in a plasma test found a bizarre virus, but still do not know the existence of HIV.

2.1969 years, in United States of San Luis, a 15-year-

old African citizens United States Junior suddenly died, her organization found HIV viruses.

3.1976 years a Norway sailors died, discover their HIV virus in the body.

4.1981 years, United States Los Angeles five homosexual who discovered HIV, which means that it formally found HIV spread of weapons of mass.

5.1983 years France scientists Mont Stanier from gay Pneumocystis carinii infection of plasma separation in a new kind of virus, the first discovery of a pathogen of scientists.
