title: Influenza virus strains with a fusion threshold of pH 5.5 or lower are inhibited by amantadine. Brief report.
abstract: Nineteen influenza virus strains were examined for susceptibility to amantadine-HCl (AMT) and for pH-thresholds of haemagglutinin-induced haemolysis. Whereas pH-thresholds below 5.5 were not seen in AMT-resistant strains, AMT-sensitive strains showed pH-thresholds either below or above 5.5.
