ABSTRACT

In the presence study, concentration of total lipids in the intestinal tapeworm Bothriocephalus acheilognathi and the intestinal tissues of its host, the common carp Cyprinus carpio, were estimated. fatty acids analysis for the cestode Bothriocephalus acheilognathi where carried out too, assisting GLC- technique. It is revealed that concentration of total lipids in the body tissues of B. acheilognathi tapeworm was 15.43±0.71mg/gm of the wet weight, whereas lipids concentration in the intestinal tissues of the infected fish was 12.86±0.17 mg/gm of the wet weight, on the other hands, lipids concentration in the intestinal tissues of the-non infected fish was 23.51 ±0.12 mg/gm wet weight. There were significant difference at P≤0.05 between concentration of total lipids in the intestinal tissues of the infected and non-infected fish. Fatty acid analysis of Bothriocephalus acheilognathi tapeworm were exhibit eight types of fatty acids depending on retention time of the authentic fatty acids; three of them were saturated (Myrestic (C14:0), Palmatic (C16:0) and Stearic (C18:0)) and three were unsaturated fatty acids (Oliec (C:18:1), linoliec (C18:2) and linolenic (c18:3)) in addition to tow unidentified fatty acids. The most dominant fatty acid was the unsaturated linoliec acid (28.3% of the total fatty acids).
