New Method for Evaluation of Virucidal Activity of Antiseptics and Disinfectants

Abstract
Counting culturable viruses adsorbed to cellulose nitrate filters (the VIRADEN method) is proposed as a simple procedure for the evaluation of the virucidal activity of antiseptics and disinfectants. The virucidal activities of two different doses of iodine, chlorine, glutaraldehyde, and chlorhexidine digluconate on poliovirus 1 were tested with a standardized procedure and with the VIRADEN method. The two procedures assayed provided similar results.
