Adsorption and maturation of poliovirus in singly and multiply infected HeLa cells.

Studies with polio-infected HeLa cells using cell disruption techniques during the early stages of infection have shown that: The inoculum of poliovirus adsorbed on HeLa cells is largely inactivated. Infective virus accumulates in a monolayer sheet of cells in advance of release into the medium. The eclipse period is shorter in multiply infected cells than in those infected with a single particle.
