THE INACTIVATION OF THE VIRUS OF EPIDEMIC INFLUENZA BY SOAPS

Area of Science:

• Virology
• Biochemistry
• Epidemiology

Background:

• Epidemic influenza poses a significant public health threat.
• Understanding virus inactivation mechanisms is crucial for developing effective antiviral strategies.

Purpose of the Study:

• To investigate the antiviral activity of specific fatty acids against epidemic influenza virus.
• To determine if fatty acid treatment affects the virus's immunogenic properties.

Main Methods:

• Assessing the inactivation capacity of oleic, linolic, and linolenic acids at pH 7.5.
• Studying variables like pH, inactivation rate, and reactant concentrations using oleic acid.
• Evaluating attempts to recover active virus from inactivated mixtures.
• Comparing the immunogenicity of active and fatty acid-inactivated virus.

Main Results:

• Oleic, linolic, and linolenic acids demonstrated significant capacity to inactivate epidemic influenza virus.
• Inactivated virus could not be recovered by altering pH, dialysis, dilution, or adding calcium chloride.
• Fatty acid treatment removed infectious properties while preserving essential immunogenic capacity.

Conclusions:

• Specific fatty acids are potent inactivators of influenza virus.
• Fatty acid treatment offers a method to render influenza virus non-infectious while retaining its ability to stimulate an immune response.
