Electromicroscopic Observation of Bombyx mori Densonucleosis Virus Infecting Insect Cell Lines
Abstract: There have not been formally reports of Bombyx mori densonucleosis virus infccting insect cell lines. In the present paper three insect overy cells of B.suppressaria, S. frugiperda and M.brassicae infected with Bombyx mori densonucleosis virus.The result is that cytopathic effect was only observed in the overy cells of B.suppressaria. The ultrastructural changes of the infected cells have been observed both in the cytoplasm and nucleus. At an early stage of infection, the infected nucleus hypertrophied grad...
