Role of sediment in the persistence of enteroviruses in the estuarine environment

Abstract

The survival of 4 enteroviruses commonly found in sewage effluents was examined when the viruses were adsorbed to marine sediments in estuarine water and compared with virus survival in estuarine water alone. Echovirus 1, coxsackieviruses B3 and A9, and poliovirus 1 survived longer when associated with marine sediment. When the estuarine water was polluted with secondarily treated sewage effluent, virus survived for prolonged periods in sediments, but not in the overlaying estuarine water.
