abstract
In the present investigation, Raillietina cesticillus a cestodes parasite infecting domestic chick (Gallus domesticus) has been investigated to study the differential distribution of metabolites. It exhibits immature, mature and gravid regions that differ in morphology, anatomy, and physiology. Glycogen content is 27.81±1.79, 34.71±0.78 and 24.05±3.02 and the total carbohydrates are 36.23±2.94, 41.32±3.05 and 34.53±1.58 mg glucose/g fresh weight of the tissue respectively whereas pyruvate levels are 4.78±0.30, 4.86±0.40 and 4.60±0.10 µg of pyruvate /gm fresh weight of the parasite tissue. The data obtained revealed that higher levels of activities were associated with mature and immature regions, whereas the gravid segment with low levels of all these metabolites. They respire by anaerobic and semi aerobic modes therefore, the yield is lesser, and they store higher levels of glycogen.
