Ecological and biochemical aspects of parasite-host interactions in transformed aquatic bodies: A case study of the cestode Triaenophorus nodulosus and its host, the northern pike Esox lucius

The lysosomal enzyme activities of the cestode Triaenophorus nodulosus and its host, the pike, in aquatic bodies with different degrees of technogenic transformation (Northern Karelia, Russia) have been studied. As has been shown, iron-ore waste causes an increase in the acid phosphatase, nuclease,...

Description
Summary:The lysosomal enzyme activities of the cestode Triaenophorus nodulosus and its host, the pike, in aquatic bodies with different degrees of technogenic transformation (Northern Karelia, Russia) have been studied. As has been shown, iron-ore waste causes an increase in the acid phosphatase, nuclease, and β-galactosidase activities of the host and a decrease in its β-glucosidase and cathepsin D activities. As a rule, the changes in the same cestode enzyme activities are the opposite. With a decrease in the technogenic load, most of the studied characteristics display the trend of approaching the corresponding values observed in a clean lake. It is assumed that the host plays a leading role in the biochemical adaptation of the parasite and its host to mineral environmental pollution.
