Phylogenetic analysis of the Neuraminidase (a) and hemagglutinin (b) genes of the H275Y mutant H1N1pdm09 Viruses isolated in mainland China in 2013–2014 influenza season. The clustered H1N1pdm09 virus with H275Y mutation in NA gene reported in Japan in 2013–2014, the United States in 2013–2014, and Australia in 2011 were indicated with a vertical line. The NA gene of the H275Y mutant H1N1pdm09 Viruses isolated in mainland China in 2013–2014 influenza season were indicated Solid circle.
