title: Lack of characteristic hexagonal surface structure on a newly isolated influenza C virus.
abstract: 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.
