[Further cytochemical researches on Microsporidia parasites of the Mediterranean shore crab, Carcinus mediterraneus Czerniavsky, 1884 (author's transl)].

A cytochemical study of Microsporidia in Carcinus mediterraneus points out the following data: acid or very acid intrasporoblastic mucopolysaccharids, are found in Thelohamia maenadis which react as sulfomucins in opposition to external asulfated mucosubstances rich in electronegative groups. In Nosema pulvis, the mucopolysaccharid compound is nearly equivalent of that of Nosema orthocladii. Both species are also characterized by the abundance of sulfured proteins in their spore walls and the lack of stock substances.
