Thirteen HIV-1 isolates from patients of different risk groups in Madrid (Spain) have been analyzed at the genetic level. Two distinct lineages of subtype B have been detected among the HIV-1 circulating in this area: one was related to SF-2/RF strains, whereas the other consists of a more heterogeneous group related to reference strain III-B. Variants of each lineage appeared to circulate preferentially within a risk group: III-B among intravenous drug users, and RF/SF-2 among male homosexuals.
对来自西班牙马德里不同风险群体患者的13株HIV-1分离株进行了基因水平分析。在该地区流行的HIV-1中检测到两种不同的B亚型谱系:一种与SF-2/RF毒株相关,而另一种由与参考毒株III-B相关的更具异质性的群体组成。每个谱系的变体似乎在一个风险群体中优先传播:静脉吸毒者中的III-B,以及男同性恋者中的RF/SF-2。
