Effect of Trimethoprim on Glycogen Contents in Freshwater Mussels, Lamellidens corrianus (Lea) & Parreysia cylindrica (Annandale & Prashad)

摘要

Freshwater bivalves, Lamellidens corrianus were exposed to acute dose of trimethoprim one of the ingredients of sulpha drug (174.80PPM) and Parreysia cylindrica (136.29PPM) up to 96 hours and chronic dose to Lamellidens corrianus of the same antibiotics (34.96 PPM) and to Parreysia cylindrica was (27.25 PPM) up to 21 days. After 24 and 96 hours of acute treatment and 7, 14 and 21 days of chronic treatment, the mantle, gills, foot, ovary, testis, digestive glands and whole body of the bivalves were separated, dried in the oven and their glycogen contents were estimated.Except gills, trimethoprim reduced the glycogen contents from most of the tissues of L. corrianus while in Parreysia cylindrica overall reduction in the glycogen depot was observed. The most affected tissue in which the great depletion observed was digestive glands.DOI: http://dx.doi.org/10.3126/ijls.v6i1.5767
