流行性感冒病毒流行性感冒病毒,简称流感病毒,是引起流行性感冒的病原体。一、生物学性状病毒多呈球状成丝状,直径80～120毫微米。病毒结构可分三层:内层是与核酸结合的蛋白质,称核蛋白;中层是包围着病毒核心的一种分子量较小的蛋白质,称内膜蛋白;外层 Influenza virus Influenza virus, referred to as influenza virus, is the causative agent of influenza. First, the biological characteristics of the virus mostly spherical into a filament, diameter 80 ~ 120 nm. The virus structure can be divided into three layers: the inner layer is a nucleic acid binding protein, called nuclear protein; the middle is surrounded by a virus core protein of a smaller molecular weight, called the inner membrane protein; outer layer
