چکیده

The removal of Escherichia coli from estuarine water was investigated. The survival of E. coli was dependent on the presence of protozoan predators and not on the presence of lytic bacteria. When indigenous protozoa were removed from estuarine water by filtration, the destruction of coliform populations was negligible. In studies designed to prevent the growth of indigenous bacterial populations without affecting protozoan populations, coliform destruction was significant.

Survival of Vibrio cholerae and Escherichia coli in estuarine waters and sediments.

In in vitro estuarine water and sediment chambers, the survival of Vibrio cholerae and Escherichia coli was determined by plate counting and direct counting techniques. V. cholerae strains included environmental, clinical, and serotype O1 and non-O1 isolates, whereas E. coli strains included ATCC 25922 and a freshly cultured human isolate. Recovery of V. cholerae varied significantly with incub...

Relationship between Frequency of Escherichia Coli and Prevalence of Salmonella and Shigella Spp. in a Natural River

Introduction: Microbial contamination prediction through detecting the indicator bacteria in natural waters is the first health and environmental step for preventing the transmission of water-associated diseases. This study was designed to determine the correlation between Escherichia coli as the indicator bacterium, on the one hand, and Salmonella and Shigella Spp. As the pathogenic bacteria, ...

Survival of Escherichia coli and Salmonella spp. in estuarine environments.

Survival of Escherichia coli and Salmonella spp. in estuarine waters was compared over a variety of seasonal temperatures during in situ exposure in diffusion chambers. Sublethal stress was measured by both selective-versus-resuscitative enumeration procedures and an electrochemical detection method. E. coli and Salmonella spp. test suspensions, prepared to minimize sublethal injury, were expos...
