Abstract
The aim of the current study was to assess synergistic effect of thermal stress, pollution and parasitic infestation on the activity of antioxidant enzymes (peroxidase, catalase, and glutathione-S-transferase) in different populations of the wide-spread species of pulmonate mollusk Lymnаea stagnаlis distributed in the Belarus Republic water bodies. It has been shown that the combined influence of anthropogenic effect and parasitic infestation on the one hand and experimental hyperthermia coupled with the parasitic invasion on the other hand affect the activity of peroxidase. The combined impact of parasitic infestation and contamination of the reservoir leads to the change of the catalase activity. No significant correlations between the studied factors and the activity of glutathione-S-transferase were found. The simultaneous exposure to elevated temperature, pollution and infectiousness of mollusks does not affect the activity of the studied enzymes.
