    • Abstract

       

      The amounts of cations Ca, P, Na, K, Cu and Zn inRaillietina tetragona (Cestoda) and in liver, intestinal tissues and blood serum of its host (Gallus gallus dotmsticus) were determined using spectrophotometry, titrimetry, flame photometry and atomic absorption spectrophotometry. Quantitative variations were observed in the distribution of these minerals in the immature, mature and gravid regions of the worm, on dry weight basis. There was a gradual decrease in Ca content of worm along the antero-posterior axis. The Na content, on the other hand showed a reverse trend with the greatest amount in the gravid proglottids. The immature region contained the highest levels of P, K and Cu. The worms showed significantly higher levels of Ca, P, Cu and Zn than the liver and intestinal tissues on dry weight basis.R. tetragona, like host liver and intestinal tissues (but unlike blood serum), had quantitative excess of K over Na and other cations.
