title: [Molecular-epidemiological characteristics of basic foci of the HIV epidemic among substance abusers in Russia].
abstract: A serological test has been developed, allowing a rapid and reliable differentiation between envA and envB genotypes in the sera from HIV-1-infected IDUs and their sexual partners. We analyzed 556 specimens from HIV-1-seropositive IDUs and their sexual partners. The sera were collected in five regions of Russia with the greatest number of HIV-1-infected IDUs. High homogeneity of HIV-1 in each of the regions was observed. In Tver, Rostov-on-Don, Nizhny Novgorod, and Krasnodar 100% sera tested belonged to the env subtype A. All the patients from the Kalinigrad region were infected with the env subtype B virus, which is apparently a recombinant.
