Survival of Aeromonas hydrophila and Escherichia coli in aquatic environments.
Survival of Aeromonas hydrophila and Escherichia coli in distilled water, pond water and effluents of anaerobic digesters were examined. Survival capabilities of A. hydrophila in various aquatic systems were similar to E. coli except in the raw effluents of anaerobic digesters, where A. hydrophila survived significantly better than E. coli for 6 days. Pathogens such as Staphylococcus aureus, Salmonella enteritidis and Vibrio cholerae were readily killed in the raw effluents of the anaerobic digester. Results explain why A. hydrophila were so numerous in many fish ponds examined in Taiwan. A. hydrophila may also be recommended as a supplemental index of fecal pollution of water supplies.
