The aim of this study was to assess the impact of effects of thermal stress and parasitic infestation on the activity of antioxidant enzymes (peroxidase, catalase and glutathione S-transferase) in different populations of wide-spread species of pulmonate mollusk Lymnaea stagnalis from water bodies with different levels of anthropogenic pollution in Belarus  - unpolluted Narach  Lake and  polluted  Chizhovsky reservoir. There are several differences were found under thermal stress exposition (35 °С). In non infected mollusсs of both populations the peroxidase activity decreased and activity of catalase increased. An activity of glutathione S-transferase increased in non infested mollusks that inhabit polluted Chizhovsky reservoir.

Key words:    peroxidase, glutathione S-transferase, catalase, anthropogenic load, parasitic infestation, trematodes, stress
