Wstępne badania nad przemianami związków wysokoenergetycznych w koracidiach Triaenophorus nodulosus (Pall.) (Cestoda) i pierwszych żywicielach pośrednich (Copepoda)

The experiments were made with highly energetic compounds in adenosine, AMP, ADP and ATP series of Cyclops vicinus Ulj. homogenates, both infected and non-infected with Triaenophorus nodulosus (Pall.) larvae (by the 14-day of procercoid growth) as well as in homogenates of Triaenophorus nodulosus larvae immediately after hatching and after 2 days of free life in water. The ATP level was found to be higher than that of the remaining adenine compounds. ATP measurements in intermediate hosts showed quantitative differences between non-infected and infected Cyclops vicinus Ulj. (Fig. 3, 4); the latter showed a great increase in ATP and reduction in AMP content, this suggesting a higher intensity of highly energetic transformations in the host organisms during the developmental phase of the parasite. In the Triaenophorus nodulosus larvae, a decrease in ATP content could be seen after two days of free life in water (Fig. 2). This is likely to be a result of the exhaustion of reserve substances (polysaccharides and phospholipids) in the ciliated membrane of Coracidia.
