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.
H275Y 奥司他韦耐药突变赋予了人类 A(H1N1)流感分离株对奥司他韦的高度耐药性。我们报告了从一名人类患者中直接分离到具有 H273Y 神经氨酸酶点突变的乙型流感病毒。该 H273Y 型乙型流感分离株对奥司他韦和帕拉米韦耐药,但对扎那米韦敏感。
