大猩猩或也是艾滋病毒来源

　　法国科学家8月2日报告，以往科学界一直认为黑猩猩携带的猿类免疫缺陷病毒(SIV)是人类免疫缺陷病毒(HIV)的最初来源，但最新发现表明，大猩猩也可能是人类艾滋病毒的来源。

　　法国鲁昂大学让-克里斯托夫·普朗捷领导的研究小组发表论文说：“我们在一名喀麦隆妇女身上发现一种新型人类免疫缺陷病毒(HIV)。它与大猩猩携带的SIV有密切关联，但没有证据表明它是HIV-1病毒或黑猩猩所携带SIV病毒的变异病毒。”

　　科学家最初在黑猩猩身上发现SIV病毒，2006年在大猩猩身上也发现SIV病毒。不过，科学家先前认为，HIV源于黑猩猩身上的SIV。黑猩猩SIV在人类猎食它们时传染给了人类并变异为可人际传播的HIV病毒。

　　普朗捷和他的研究小组在论文中写道：“我们的发现表明，大猩猩，像黑猩猩一样，可能是HIV-1病毒的来源。”

　　论文发表在最新一期英国《自然》月刊上。

　　HIV-1病毒与HIV-2病毒都会导致艾滋病(全称“获得性免疫免疫缺陷综合征”)，人际传播途径相同，但是HIV-1病毒在全世界都有发现，而HIV-2病毒常见于西非。

　　报告说，这名喀麦隆妇女现年62岁。她2004年由喀麦隆移居法国后被发现感染这种新型HIV。她不曾接触过大猩猩，但丧偶后曾与多名男子发生过性关系。研究人员说，她可能从另外一个人而不是从动物那里感染上病毒。研究人员认为这表明发现于这名妇女身上的这种病毒可在人际间传播。

　　他们说，这一发现警示世人“需要继续密切注意新的HIV变体的出现，特别是在非洲中西部，那里是所有已知HIV病毒的来源地。”

Gorillas, and is also the source of HIV

August 2 French scientists reported in the past scientists have always thought that chimpanzees carry simian immunodeficiency virus (SIV) is a human immunodeficiency virus (HIV) of the original source, but the latest findings suggest that gorillas may be the human immunodeficiency virus来源.

Let the University of Rouen, France - Christophe Fu Pulang Czech research team led by Publications, said: "We are a Cameroonian women who have discovered a new type of human immunodeficiency virus (HIV). It is with the gorillas carry SIV have closely related, but there is no evidence that it is the HIV-1 virus or chimpanzee SIV virus carried by the mutant virus. "

Scientists originally found in the chimpanzee SIV virus, the gorilla who in 2006 also found that SIV virus. However, scientists previously thought, HIV from the body chimpanzee SIV. Chimpanzee SIV in the human predators when they are transmitted to humans and mutate into Keren-human transmission of the HIV virus.

Plantier and his research team wrote in the paper: "Our findings suggest that gorillas, like chimpanzees, as might be the source of HIV-1 virus."

Papers published in the latest issue of British "Nature" magazine on.

HIV-1 virus and HIV-2 virus can lead to AIDS (full name of the "Acquired Immune Immune Deficiency Syndrome"), interpersonal communication channels the same, but the HIV-1 virus in the world have discovered, but the HIV-2 virus, common in West Africa .

The report said that Cameroonian women were aged 62 years. She emigrated to France in 2004 by Cameroon, was found infected with this new type of HIV. She has not come into contact with gorillas, but the death of a spouse after which he worked with a number of men had had sex with. The researchers said that she was likely one person from another, rather than from animals infected with the virus. The researchers think that this shows that the woman found the body of this virus can be spread from person to person.

They said the discovery warn us that "need to continue to pay close attention to the new variant of the emergence of HIV, especially in central and western Africa, where all known sources of HIV virus."
