新华网巴黎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。

这项研究由法国国家人类免疫缺陷病毒参照中心和鲁昂医学中心共同完成。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。她认为，未来可能会发现新的感染Ｐ亚型病毒的艾滋病病例。

    莱奥斯还透露，患者目前状况稳定，研究人员根据新病毒的基因组为其制定了治疗方案，治疗产生了效果。

     Xinhua Paris August 2 (Xinhua Li Xuemei) a virologist from the French team announced that they successfully identified the type 1 HIV (HIV-1) a new variant of this new subtype virus in the genetic makeup with apes immunodeficiency virus (SIV) are very similar.

     Researchers in the latest issue of the British "Nature - Medicine" magazine published an article that the variant virus is a Cameroon-born patients found. 1 HIV (HIV-1), including M, N, O three subtypes of the virus, the vast majority of the world's AIDS cases are among the M subtypes, O, N subtype is relatively rare. Initially, the researchers believe that the new virus belonging to subtype O, but to break the virus genome and found that this is a new subtype, so named for the P subtype.

     The study was conducted by the French national human immunodeficiency virus reference center and the completion of Rouen Medical Center.马里莱奥斯a member of the research team told the media that the new virus is likely to be from the apes immunodeficiency virus (SIV) from the change, but it is difficult to define a specific time, as scientists apes immunodeficiency virus (SIV) also do not know much about. She believes that the future may find a new subtype of virus infection P AIDS cases.

     Agathocleous also revealed that patients are in stable condition, the researchers according to the new virus genome for the development of a treatment program, have had the effect of treatment.
