There were significant differences at p≤0.05 between the concentration of total carbohydrates, protiens and lipides: (240, 181 μg/ml and 196mg/100ml, respectevely in the pigeon cestode and 105, 153 μg/ml and 133mg/100ml, respectively in the frog cestode).High performance liquid chromatography technique (HPLC) analysis for fatty acid elucidated that each of the two helminthes contain six types of fatty acid. O. bofonis found to have three saturated fatty acids: stearic, palmatic and myristic, 2.72%, 2.29% and 0.89% respectively and three unsaturated fatty acid: linoleic, linolienic and oliec, 73.13%, 13.07% and 7.91%, respectively. On the other hands, C. columbae found to have four saturated fatty acid: stearic, palmatic, myristic and caproic, 51.43%, 45.89%, 2.38% and 0.19% respectively, and two unsaturated fatty acides: linoleic, linolienic, 0.09% and 0.06%, respectively.Enzymatic study pointed to the significant differences at p≤0.05 between the enzymes activity in frog cestode and that of pigeon cestode. Activity of G6PDH and LDH (cytosolic enzymes) and SDH and FR (Mitochondrial respiretory enzymes), were :7.514 U/L, 56 IU/L, 130 nm FAD/min/ mg protien and 198 nm NADH/min/mg protien in O. bofonis extract; and 7.514 U/L, 56 IU/L, 130 nm FAD/min/ mg protien and 198 nm NADH/min/mg protien in C. columbae extract.The prevous resultes may reffered to a relativly higher activity of the enzymes under study, those take a part in glycolisis and energy metabolism libration in O. bofonis than that in C. columbia, in spite of that the occumulated souces of energy were more aboundant in pigeon cestode.
