Abstract
The effect of estuarine sediment on the thermoinactivation of poliovirus type 1 and echovirus type 1 was evaluated. Poliovirus survival was prolonged at 24 and 37 degrees C but not at 4 degrees C in the presence of sediment over the time periods observed. Further inactivation studies were performed at 50 and 55 degrees C to maximize the thermal effects, and similar protection was observed. The supernatant fluid from a mixture of seawater and sediment lacked the protective effect against thermoinactivation, suggesting that prolonged virus survival in the presence of sediment was due to adsorption to particulates. From these observations, it appears that the adsorption of enteroviruses to estuarine sediments may play a significant role in protecting them against thermoinactivation.
