Abstract excerpt
Limited information is available concerning the molecular drift of the influenza neuraminidase (NA) genes. We report on the genetic variability of the NA gene from 31 influenza A:H3N2 viruses isolated in the Province of Québec (Canada) during the last three flu seasons (1997-2000). Amino acid substitutions within the NA protein were observed at rates of 1.01% and 0.45% between strains of the 1997-1998 and...
