    • The present invention is directed toward nucleic-acid based methodologies for the detection of human immunodeficiency virus (HIV) nucleic acids in a sample. A novel HIV-1 isolate, designated MVP5180/91, was isolated from a West African Cameroonian patient with immunodeficiency. Nucleic acid and amino acid sequence comparisons of this isolate, with other HIV-1 strains of subtypes A-E and HIV-2 isolates, demonstrated that this virus shares only limited homology with other known HIV-1 and -2 isolates. However, this virus does display some genetic relatedness to another Cameroonian isolate designated ANT-70. These viruses form the basis for a new HIV-1 group which has been designated subtype O. An immunologically important epitope, corresponding to amino acids 601-623 of the MVP5180/91 transmembrane envelope glycoprotein, was identified. Labeled nucleic acids can be prepared from the nucleotide sequence encoding this region and employed in standard hybridization assays to detect HIV-1 nucleic acids. Alternatively, oligonucleotide primers can also be prepared from this region and employed in polymerase chain reaction (PCR) assays to detect viral-specific nucleic acids.
    • 本发明涉及用于检测样品中的人类免疫缺陷病毒(HIV)核酸的基于核酸的方法。 从具有免疫缺陷的西非喀麦隆患者中分离出一种名为MVP5180 / 91的新型HIV-1分离株。 该分离株与其他HIV-1亚型A-E和HIV-2分离株的核酸和氨基酸序列比较表明,该病毒与其他已知的HIV-1和-2分离株仅具有有限的同源性。 然而,这种病毒确实显示与另一个指定为ANT-70的喀麦隆分离株有一些遗传相关性。 这些病毒构成了已被指定为亚型O的新的HIV-1组的基础。鉴定了与MVP5180 / 91跨膜包膜糖蛋白的氨基酸601-623相当的免疫重要的表位。 标记的核酸可以从编码该区域的核苷酸序列制备,并用于标准杂交测定以检测HIV-1核酸。 或者,也可以从该区域制备寡核苷酸引物,并用于聚合酶链反应(PCR)测定中以检测病毒特异性核酸。
