title: A scanning electron microscopic study of SV40 infected cells.
abstract: The surface of the SV40-infected African green monkey kidney (AGMK) cells was studied morphologically by scanning electron microscopy. In 24 hr post infection (p.i.), the cell surface was covered with slightly elongated microvilli. The microvilli increased in number. In 96 hr.p.i. most of the cells showed SV40-specific cytopathic effects (CPE). Nuclear swellings and the elongation of microvilli were eminent. Microvilli were observed projecting with high densities especially on the nuclear portions of the cell surfaces. Features suggesting cytoplasmic vacuolization were also observed in some cells. Spherical particles viewed in some of the cells at the late stage of infection were considered SV40 virions. Their origin was also discussed.
