    Abstract

    The H275Y oseltamivir resistance mutation confers high level resistance to oseltamivir in isolates of human A/H1N1 influenza. We report the recovery and identification of an influenza B virus with the H273Y neuraminidase point mutation directly from a human patient. The H273Y influenza B isolate is resistant to oseltamivir and peramivir but sensitive to zanamivir.
