The Cuticle of Nematode Larvæ

Abstract

THE infective larval stage of many nematode parasites is ensheathed in the uncast cuticle of the second stage. The sheath is regarded as having some protective function in a larval stage which is more resistant to environmental fluctuations than the earlier stages. A method has been devised for separating the sheaths from larvæ, and it has been found that their protein complement is water-soluble. In this communication, the amino-acid composition of these proteins is discussed.
