获得性免疫缺陷综合征(AlDS)是细胞免疫系统遭到人类 T 细胞白血病/淋巴瘤病毒(HTLV)危害的一种传染病。近年已从各类病例中分离出三个亚型病毒系,目前正在分析研究其病毒的基因序列。血清流行病学调查结果表明,HTLV 可通过血液、精液或唾液等进行水平传播,而健康人群中的某些血清抗体阳性者,也可能就是带毒者。本文就其传播途径试述近期的研究进展。血源传播从血液中分离出逆转录病毒及临床和体外的实验结果表明,AIDS 病原通过血液或血液制品传播是可以肯定的。近期的研究进一步证实,健康同性恋男性的外周血单个核细胞中也有 HTLV-Ⅲ的阳性抗原存在。以 Ficoll-Hypaque 密梯度分
Acquired immune deficiency syndrome (AlDS) is an infectious disease in which the cellular immune system is compromised by human T-cell leukemia / lymphoma virus (HTLV). In recent years, three subtypes of virus strains have been isolated from various types of cases, and the gene sequences of their viruses are currently being analyzed. Serological epidemiological findings indicate that HTLV can be transmitted horizontally by blood, semen or saliva, while some of the healthy people may be seronegative. This article discusses recent advances in its transmission. Blood-borne Transmission of retroviruses isolated from the blood and clinical and in vitro experimental results show that AIDS pathogens can be transmitted by blood or blood products is certain. Recent studies further confirmed that healthy homosexual male peripheral blood mononuclear cells also have HTLV-Ⅲ positive antigen exists. Ficoll-Hypaque MI
