Survival and Rate of Death of Intestinal Bacteria in Sea Water

Abstract

The exps. demonstrate the reliability and selectivity of the Wilson-Blair, bismuth-sulphite medium for typhoid isolation and quantitative studies in polluted water. Data are presented showing rates of death of Eberthella typhosa and Escherichia coli under closely simulated natural conditions in polluted sea water. The possibility of survival of both species over a period of at least 10 mo. is indicated. E. coli is shown to be sufficiently resistant to sea water to serve as an indicator of pollution in such an environment.
