The hexagonal surface structure believed to be characteristic for influenza C virus was not initially observed for a newly isolated virus of this type. After a few additional egg passages of the virus, however, the hexagonal structure could be readily seen on many virions.
最初在一种新分离出的C型流感病毒中未观察到被认为是该病毒特征的六边形表面结构。然而,在该病毒经过几次额外的鸡胚传代后,在许多病毒粒子上可以很容易地看到六边形结构。
