To develop a mouse model for testing receptor attachment inhibitors of human influenza viruses, the human clinical virus isolate in MDCK cells A/NIB/23/89M (H1N1) was adapted to mice by serial passaging through mouse lungs. The adaptation enhanced the viral pathogenicity for mice, but preserved the virus receptor binding phenotype, preferential binding to(More)
OBJECTIVE Parallel testing of inactivated (split and whole virion) and live vaccine was conducted to compare the immunogenicity and protective efficacy against homologous and heterosubtypic challenge by H5N1 highly pathogenic avian influenza virus. METHOD Four experimental live vaccines based on two H5N1 influenza virus strains were tested; two of them(More)
The highly pathogenic A/chicken/Kurgan/3/2005, (K/05) H5N1 influenza virus was attenuated using selection in an environment simulating the life cycle of wild duck influenza viruses. The goal of this work was the selection of viruses which are more stable for protease cleavage and low pH than the parent virus. The attenuated virus (K/at) was nonpathogenic(More)
An influenza virus A/gull/Moscow/3100/2006 (H6N2) was isolated from gull’ faeces within the precincts of Moscow in autumn 2006. Nucleotide sequence of complete genome (GenBank, EU152234-EU152241) and genotype (K, G, D, 6B, F, 2D, F, 1E) for this virus were determined. Phylogenetic analysis suggests that the H6N2 virus derived by numerous reassortment(More)
Four H5N2 experimental vaccine strains and the apathogenic wild duck H5N3 influenza virus A/duck/ Moscow/4182/2010 (dk/4182) were tested as a live poultry vaccine. Experimental strains had the hemagglutinin of the A/Vietnam/1203/04 strain lacking the polybasic HA cleavage site or the hemagglutinin from attenuated virus (Ku/ at) that was derived from the(More)
The change in the phenotypic properties resulting from amino acid substitutions in the hemagglutinin (HA) molecule is an important link in the evolutionary process of influenza viruses. It is believed to be one of the mechanisms of the emergence of highly pathogenic strains of influenza A viruses, including subtype H5N1. Using the site-directed mutagenesis,(More)
Development of an effective, broadly-active and safe vaccine for protection of poultry from H5N1 highly pathogenic avian influenza viruses (HPAIVs) remains an important practical goal. In this study we used a low pathogenic wild aquatic bird virus isolate А/duck/Moscow/4182/2010 (H5N3) (dk/4182) as a live candidate vaccine. We compared this virus with four(More)
