Serum lipoproteins were found to carry almost all of the inhibitory activity, which specifically resided in the phospholipids of these lipoproteins. Commercially available phospholipids and cholesterol were also effective inhibitors of virus haemagglutination. The inhibitory activity of the mixture of cholesterol and lecithin tested against the haemagglutinins of vesicular stomatitis virus, rabies virus and an arbovirus (LaCrosse strain of California arbovirus group) were 2 to 8 times higher than that for the lipids alone, whereas the inhibitory activity of the mixture of cholesterol and palmitic acid was not higher than that of cholesterol alone. Adsorption with kaolin, as well as fractionation by DEAE-cellulose chromatography, effectively separated the non-specific inhibitors from specific antibodies contained in burro anti-rabies virus serum., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-22-3-309
