A preliminary survey of the relative abundance of fecal coliform bacteria in water and sediment and in the fresh water bivalve,Lamellidens marginalis, of the Buriganga river, Bangladesh.
Studies on the concentration of fecal coliforms in freshwater bivalves were carried out using a spread plate method and membrane fecal coliform medium. Water, sediment, and bivalves collected from the Buriganga River at Dhaka, Bangladesh, were examined. As demonstrated in many previous studies, fecal coliform counts were consistently higher for the bivalve tissue than those for water and sediment samples; in the bivalveLamellidens marginalis, they were ∼10.0- to 87.0-fold higher than those in water, and 2.0- to 11.0-fold higher than those in sediment.
