The purpose of this study was to investigate mumps vaccine failures (VF) in a highly vaccinated population of Minsk, Belarus, and to investigate a possible role for virus strain-specific immunity. During our 3-year study period, 22 adults were admitted to the Infectious Diseases Hospital in Minsk with a diagnosis of mumps. A genotype H1 mumps virus (MuV)(More)
The aims of this study were to estimate the importance of vaccine failure (VF) in cases of mumps during 2002-2004 in the city of Novosibirsk, Western Siberia, Russia, and to genotype the responsible virus strain. Mumps virus-specific RT-PCR testing of saliva was performed for 18 cases of mumps. Sera were tested for IgM and IgG, IgG avidity, and the ability(More)
The ecology of avian influenza (AI) viruses in wild aquatic birds of Asia is poorly understood, especially for the H5N1 high pathogenicity AI (HPAI) viruses. From March 2006 through November 2008, 20 AI viruses were isolated in the Crimea region of Ukraine with an overall frequency of virus recovery of 3.3%. All the viruses were isolated from three species(More)
While the proportion of measles cases in vaccinees is expected to increase as vaccine coverage increases, such cases must be carefully investigated. The present study was conducted to examine possible contributions to vaccine failures (VFs) and to genetically characterize measles virus (MV) strains circulating in Novosibirsk, Russia during 2000-2005.(More)
In this work we report the mumps vaccine virus shedding based on the laboratory confirmed cases of the mumps virus (MuV) infection. The likely epidemiological sources of the transmitted mumps virus were children who were recently vaccinated with the mumps vaccine containing Leningrad-Zagreb or Leningrad-3 MuV. The etiology of the described cases of the(More)
AIM To analyze influenza viruses isolated in the 2008-2009 autumn-winter season, and to test sera collected in the south of Western Siberia during the beginning and the end of the epidemic seasons from 2007 until the A/H1N1 pandemic. MATERIALS AND METHODS Total 149 clinical samples were analyzed and 2190 blood sera were tested. During the 2008-2009 season(More)
Recombinant proteins rN (nucleocapsid) and rH/Nh (hemagglutinin) of the measles virus strain NovO/96 of genotype A were obtained. The immunobiological properties of the proteins were studied in the reaction with a panel of positive and negative sera. Mice of the line Balb/C were immunized with recombinant proteins and native antigen of the measles virus(More)
AIM Monitoring of post-vaccinal complications in children immunized with a parotitis vaccine. MATERIALS AND METHODS Observation of 198 945 children, immunized with 16 lots of parotitis vaccine with Leningrad-3 strain (L-3), was carried out for 3 years. Paired samples of sera and saliva were obtained from children, in whom adverse events were registered(More)
