Abstract: | The nature and amount of excretory products of Isoparorchis hypselobagri, a digenetic trematode inhabiting the swim bladder of Wallago attu have been studied. The parasites were kept in PBS media without glucose (control) and with glucose (treated) successfully up to 300 h and different excretory products were estimated at an interval of 12 h. The quantitative estimation of excreted uric acid in I. hypselobagri was revealed less in amount in the flukes which were kept in vitro in the control incubation media than those considered from the treated incubation media. The highest amount of uric acid excreted in control media was 6.72 mg % at 204 h, and in treated condition 16.658 mg % after 216 h of incubation. The lowest amount of uric acid excreted, 0.186 mg % in control media after 252 h of incubation and 2.896 mg % in treated media after 192 h of incubation. The rate of excretion of uric acid in treated condition after every 12 h of incubation is much higher than the control. Significant amount of uric acid have also been recorded in the swim bladder washings of host. It is apparent that the amount of excreted uric acid depends on the number and weight of the parasites harbor. Results suggest that I. hypselobagri is ammonotelic, ureotelic and also uricotelic trematode. |
