Abstract: | Summary Influenza A2/Singapore and A2/Hong Kong virus strains formed plaques in monolayers of monkey kidney and dog kidney cells. Using a serum-free overlay containing Earle's balanced salt solution with 1% lactalbumin hydrolysate, 1.4 g/1 sodium bicarbonate and 0.6% agarose, plaque formation occurred in 4–7 days. By incorporating compound in the overlay, plaque inhibition was demonstrated by Amantadine, Rimantadine and the isoquinoline derivatives designated Pfizer UK-2054, UK-2617, UK-2762 and UK-2888. |
