The aim of the current investigation was to determine the frequency of HCV recombinants in intravenous drug users (IVDU) from two European countries. HCV(More)
METHODS 6,217 sera samples collected from volunteers in six epidemiologically different regions of Russia were tested for serological and molecular markers of HBV infection. A mathematical model developed by the U.S. Centers for Disease Control and Prevention was used to estimate the effect of vaccination and birth dose coverage on the incidence of HB and(More)

MATERIALS AND METHODS Epidemiological analysis of HA cases and contact persons in Erzinsky and Kyzyl regions of Tyva Republic was performed. Class M and G antibodies to HAV were determined in serum samples (n = 28), and HAV(More)
The spread and genotypical variability of GBV-C virus were determined among the HIV-positive patients in the Russian Federation. More than a fourth (26.2%) of the HIV-infected patients were shown to have GBV-C coinfection; all virus isolates belonged to genotype 2 with a predominance of subtype 2a. Analysis of the impact of GBV-C coinfection on HIV burden(More)
AIM Evaluate the effect of mass vaccination against hepatitis B implemented within the framework of national project Health on the rate of development of unfavorable outcomes of infection and on average lifetime of the population of Russia. MATERIALS AND METHODS Hepatitis B markers (HBsAg, anti-HBc, HBeAg, anti-HBe) were determined by enzyme immunoassayin(More)
The detection of HBsAg in blood serum using immune-enzyme analysis techniques decisively matters both for diagnostics of acute and chronic hepatitis B and screening of donor's blood and its components, controls of persons from risk groups of hepatitis B injection. The making of panels containing wide specter of samples of blood serums with sero-variants and(More)
