Abstract excerpt
A naturally-occurring H275Y oseltamivir resistant variant of influenza A (H1N1) virus emerged in 2007, subsequently becoming prevalent worldwide, via an undetermined mechanism. To understand the antigenic properties of the H275Y variant, oseltamivir resistant and susceptible strains of H1N1 viruses were analyzed by hemagglutination inhibition (HI) and microneutralization assays. HI analysis with H1-positive sera...
