Physiological studies on trematodes: calcium, magnesium and phosphorus content

Abstract

1. Four trematodes,Gastrothylax crumenifer, Cotylophoron cotylophorum, Paramphistomum explanatumandFasciola giganticahave been used for quantitative analysis of their inorganic constituents.2. Calcium, magnesium and phosphorus content have been determined.3. All the four trematodes contain large amounts of phosphorus (0·61–1·05%); but the amounts of calcium (0·025–0·045%) and magnesium (0·029–0·065 %) are small.
