We studied biological characteristics of influenza A(H1N1)pdm09 virus circulating in Siberia during the 2009 pandemic and the post-pandemic period of 2011. BALB/c mice were chosen as the experimental model. Virus titers in the lungs were evaluated on days 1, 3, 6 and blood serum titers on day 15 after infection with different strains. Blood sera of convalescents after influenza of 2010-2011 epidemic season were analyzed. Influenza A(H1N1)pdm09 virus strains isolated during the post-pandemic period of 2011 were characterized by low epidemic activity and virulence in comparison with the strains isolated during 2009 pandemic period, which indicates completion of the pandemic cycle.
