THE EFFECT OF TRIMETHOPRIM ON OXYGEN CONSUMPTION OF THE FRESHWATER BIVALVE, LAMELLIDENS CORRIANLIS (LEA).H. P.NAGPURE AND S.P. ZAMBARE
Freshwater bivalves Lamellidens corrianus were exposed to acute concentration (174.80 PPM) up to 96 hrs and chronic concentration (34.96 PPM) up to 21 days to trimethoprim. The rate of oxygen consumption of the bivalve, Lamellidens corrianus was measured after acute exposure of 24, 48, 72 and 96 hrs and chronic exposure of 7, 14 and 21 days to trimethoprim, one of the ingredients of sulfa drug. The decrease in oxygen consumption was observed in trimthoprim treated animals. The decrease may be due to drug stress on metabolic activities and reduction of the number of the pathogens invading bivalve.
