  • Title: [Physiological specificity of the interaction between Traenophorus nodulosus (Cestoda) and its host--fishes].
    Author: Izvekova GI.
    Journal: Parazitologiia; 2001; 35(1):60-8. PubMed ID: 11547436.
    Abstract:
    The influence of the T. nodulosus plerocercoid invasion on the liver of the intermediate fish hosts (perch) was studied. The water, protein, glycogen and glucose contents was examined in adult worms inhabiting the intestine of definitive hosts (pike), the rate of glucose accumulation along the strobile of parasite and an ability of adult worms to hydrolyze the main nutrients was also investigated. As a result of the plerocercoid infection, the glucose and glycogen contents in the liver of perch juveniles decreased, while the wet weight of liver increased. It was found, that the water and protein contents from the anterior to posterior section of strobile in T. nodulosus adults was not significantly different, while the glucose contents and the rate of its accumulation decreased. The data confirming the possibility to realize the final stages of protein and carbohydrate hydrolisis with the participation of membrane digestion on the surface of helminths and proving the ability of cestodes. The problems of relations of T. nodulosus with intermediate and definitive hosts at the level of the whole organisms are discussed.
