新华社专电法国科学家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(H
IV)。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。"

艾滋病病毒新变种被命名为P亚型
新华社巴黎8月2日电(记者李学梅)一个由法国病毒学家组成的研究小组日前宣布,他们成功辨认出1型艾滋病病毒(HIV-1)的一个新变种,这种新的亚型病毒在基因构成上与猿类免疫缺陷病毒(SIV)十分相似。
研究人员在最新一期英国《自然-医学》月刊上发表文章说,该变种病毒是在一名喀麦隆裔病人身上发现的。1型艾滋病病毒(HIV-1)包括M、N、O三种亚型病毒,目前世界上绝大多数艾滋病病例都属于M亚型,O、N亚型相对比较少见。研究人员起初认为新病毒属于O亚型,但是对病毒基因组进行破解后发现,这是一种全新的亚型,因此将其命名为P亚型。
研究小组成员之一马里·莱奥斯对媒体表示,新病毒很可能是从猿类免疫缺陷病毒(SIV)转变而来,但具体时间很难界定,因为科学家对猿类免疫缺陷病毒(SIV)还不甚了解。

Gorillas, and is also a source of human AIDS
Source: China Daily | Date: August 4, 2009
Ta Kung Pao Xinhua News Agency 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 human the source of HIV.
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 (H
IV). Carry it with gorillas are closely related to SIV, 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 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 after the death of a spouse than men with the sexual relationship occurred. 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."

New variant of HIV subtypes, named P
Xinhua News Agency, Paris, August 2 (Reporter Li Xuemei) - One by the French team of virologists announced that they were successful in identifying HIV-1 (HIV-1), a new variant of this new subtype of virus In the genetic make-up with the simian immunodeficiency virus (SIV) are very similar.
The researchers in the latest issue of the British "Nature - Medicine" magazine published an article that the variant virus is in a Cameroon-born patients found. HIV-1 (HIV-1), including M, N, O three kinds of subtypes, the vast majority of the world's AIDS cases belong to the M subtypes, O, N subtypes are relatively rare. The researchers initially considered that the new virus belongs to the O subtype, but it cracked the virus genome and found that this is a new subtype, it will be named P subtype.
马里莱奥斯 a member of the research team told the media that the new virus is likely to be from the simian immunodeficiency virus (SIV) changed from, but the exact time, hard to define, because scientists simian immunodeficiency virus (SIV) still not well understood.
