Abstract
Utilizing the de-embryonated egg prepn. the organic phosphate fractions of the chorio-allantoic membrane were studied before and after infection with PR-8 strain of virus. Following infection, a profound decrease in the phospholipid fraction was noted; 50-60% of the liberated P was recovered from the medium in a lipid bound form; and there was an increased incorporation of p32 into the phospholipid fraction. No significant changes occurred in the nucleic acid fractions.
