Estimation of in vitro Monclavit-1 Virucide Activity against Influenza Virus A (H5N1)

Abstract

The virucide activity of Monclavit-1 against the influenza virus A/Chicken/Kurgan/2/Russia/05 (H5N1) was investigated in the MDCK cell culture. It was shown that at a temperature of 14.0±1.0°C Monclavit-1 in a 20-fold dilution within an hour inactivated the cytopathic activity of the virus and the specific hemagglutinin generation by 100 and 87.5% respectively. In a 40-fold dilution it inactivated at the average by 50% both the cytopathic activity and the specific hemagglutinin generation. In an 80-fold dilution it inactivated the cytopathic activity at the average by 20%. In a 160-fold dilution it did not inactivate the pathogen. At a temperature of 25.0±1.0°C Monclavit-1 inactivated the influenza virus A/Chicken/Kurgan/2/Russia/05 (H5N1) by 90.0% only in the highest concentration.
