[Effect of trematoda infection and different concentrations of surface active agents onto physical and chemical characteristics of haemolymph of Planorbarius corneus (Mollusca: Pulmonata)].

Effect of trematod infection and different concentrations of detergent (20, 50, 80 mg/dm3) onto physical and chemical characteristics of haemolymph of Planorbarius corneus (content of Hb, density, active reaction, amount of Hb per unit of total mass and soft mass of the body) have been investigated. It was noted that all changes of named characteristics caused by detergent were more pronounced in infected mollusks.
