Summary
Three-dimensional structures of the core of Marek's disease virus and herpesvirus of turkey were examined by the tilting apparatus of an electron microscope. Various types of the core found in the infected cells were considered to represent developmental stages of the viruses. The basic structure of the core consisted of a toroid surrounding a cylindrical mass, which was clearly demonstrated by tilting the core in two directions. A cylindrical mass spooled by more than two toroids, which seemed to constitute a spiral band of 10 to 20 nm, was demonstrated. The maturation process of the cores of the viruses was also discussed.
