The occurrence of proteolipid antigens in Schistosoma mansoni.

Adult Schistosoma mansoni were shown to synthesize a peptide containing lipid against which an antiserum could be raised in rabbits. The proteolipid purified by silicic acid chromatography was soluble in chloroform/methanol mixtures, it was very hydrophobic and contained fatty acids in its molecule, as well as other unidentified neutral lipids.
