ELECTRICAL-CONDUCTIVITY DISPERSION AS A PROBE OF MEMBRANE MODIFICATIONS IN MOUSE POLYOMAVIRUS INFECTED-CELLS IN CULTURE

In this report we investigate the inhibition of membrane conductivity, due to the murine polyomavirus infection in permissive cells in cultu re. We define experimental conditions to have reproducible results and demonstrate that the intensity of the effects on the cell membrane, d epends upon the virus titer used in the infection. Finally, the virus dependent effects disappear if the infection is performed in the prese nce of a drug that inhibits polymavirus DNA replication.
