title: Effects of some sugars, amino acids, glycerol and alpha-glycerophosphate on oxygen uptake of some digenetic trematodes.
abstract: Effect of various substrates on the oxygen uptake of some digenetic trematodes -- Srivastavaia indica, Gastrothylax crumenifer, Gigantocotyle explanatum from the buffalo, Bubalus bubalis and Isoparorchis hypselobagri from the fish Wallago attu was studied. In all the four species, the effect of various substrates except maltose was found to be stimulatory. The inhibitory or stimulatory effect of these substrates on oxygen uptake reflects the importance of these compounds in the energy metabolism. In spite of the fact that these trematodes were subjected to similar concentration of substrates, the percentage change in oxygen uptake is different in each of the trematodes, the differential utilization is probably related to the different ecophysiological conditions of the habitat of these trematodes. Such studies can be useful in devising better in vitro culture media for these trematodes.
