Nippostrongylus and Toxoplasma, Volume 7, Symposia of the British Society for Parasitology

Abstract

Section entitled: Studies on Nippostrongylus. The three articles that constitute this section are entitled: Nippostrongylus brasiliensis: Some aspects of the fine structure and biology of the infective larva and the adult by D. L. Lee, Biochemistry of Nippostrongylus brasiliensis and other nematodes by C. D. Ginger, and Immunity to Nippostrongylus brasiliensis by B. M. Ogilvie.The purpose of Dr. Lee's article is to relate the structure of certain tissues and organs of Nippostrongylus as seen under the electron microscope to the general biology of the nematode. The structure and function of the cuticle and alimentary tract of the third-stage larva and adult worm are described and discussed, as well as the excretory system of the adult. The resistance of the larva to adverse physical conditions and to chemicals is interpreted on the basis of the composition of the several layers of the cuticle. The matrix layer of the adult cuticle is considered to be a fluid-filled layer containing hemoglobin.
