The lipid composition of both intracellular and extracellular forms of the ERA strain of rabies virus grown in BHK/21 cells was determined. The lipids from purified preparations of both intracellular and extracellular virus yielded 57 and 58% neutral lipid, respectively. The phospholipids of the intracellular and extracellular virus constituted 43 and 42%, respectively. Triglyceride and cholesterol appear to be the major neutral lipids, whereas sphingomyelin, phosphatidylethanolamine, and phosphatidylcholine comprise the major bulk of phospholipid in both virus types. The molar ratio of cholesterol to phospholipid was 0.87 (intracellular) and 0.92 (extracellular). On the basis of the data presented, it is reasonable to assume that the lipids of both intracellular and extracellular rabies virus are similar.
Galactose-fed chicks have been found to develop severe hyperosmolar dehydration. Although biochemical abnormalities have been observed in the brain of the galactose-toxic chick, the observed physiologic alteration of serum osmolality could be the major factor responsible for the galactose toxicity syndrome in the chick.
