Abstract
Summary
Marked differences were noted among strains of influenza with respect to adsorption to powdered cholesterol, palmitic acid and stearic acid. It has been shown that some strains suspended in allantoic fluids adsorb to lipids less efficiently than when suspended in buffered saline. Behavior of type B/GL strain was significantly different from type A strains, especially with cholesterol or palmitic acid as adsorbent. Mixtures of minimal amounts of influenza virus with cholesterol or stearic acid elicited an enhanced antibody response in animals when tested at 3 weeks.
