Infectious bursal disease virus of chickens was purified, and its structure was examined by the negative-staining technique in the electron microscope. The buoyant density of infectious bursal disease virus in CsCl was found to be 1.34 g/cm(3). The morphological details suggest that the capsid of the virion consists of a single layer of 32 capsomeres arranged in 5:3:2 symmetry. The virion measured about 55 nm in diameter and had no envelope.
鸡传染性法氏囊病病毒被提纯,并运用电子显微镜中的负染技术对其结构进行了检测。结果发现,传染性法氏囊病病毒在氯化铯中的浮密度为1.34克/立方厘米。形态学细节表明,病毒粒子的衣壳由32个壳粒组成的单层结构,呈5:3:2对称排列。病毒粒子直径约为55纳米,无包膜。
