[Determination of the cercarial lipids and relations with superficial human cutaneous lipids (author's transl)].

The lipid class composition of cercariae of Schistosoma mansoni and skin surface has been examined by thin lager chromatography. Free sterols, sterol esters, triglycerides, phospholipids were major components of cercarial lipids, triglycerides, wax esters, free fatty acids, squalen were major components of skin surface lipids. An examination of fatty acids of total cercarial and skin surface lipids revealed that C16, C18, C18=, C16=, C18= were major components.
