Abstract
The "activation energy" values for virus inactivation (22.2 kcal/mol) calculated using Arrenius formula and the levels of accumulation of the final product of lipid peroxidation, fluorescent pigment (21.2 kcal/mol), in virus envelopes were found to be in good correlation for purified influenza A/PR8/34 virus suspensions stored at temperatures from 6 to 37 degrees C. A "lipid" mechanism of inactivation of enveloped viruses is proposed, permitting, together with the "nucleic" and "protein" mechanisms, a satisfactory interpretation of the relationship between the stability of viral material and the medium composition, lipid composition of virus envelopes, and other factors.
