Lipids in hydatid fluid collected from lungs and livers of sheep and man.

Hydatid fluid collected from the lungs and livers of sheep and humans was analysed for protein and lipid composition. There were no marked differences in the composition of these parameters and the major lipids were triglycerides and diglycerides. The phospholipids, which formed the minor fraction, were mainly phosphatidyl choline and phosphatidyl inositol. Cholesterol present was in the free form.
