Brief report (Article) http://repub.eur.nl/res/pub/15004/ 1986-01-01T00:00:00Z 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.
