Survival of Escherichia coli in lake bottom sediment.
The survival of Escherichia coli in bottom sediment (Lake Onalaska, navigation pool no. 7, Mississippi River) was studied by using in situ dialysis culture of sterile (autoclaved) and unsterile sediment samples. Bags made from dialysis tubing were filled with either course sand sediment (28.8% fine) or organic, silty clay sediment (77.2% fine) and placed at the sediment-water interface. Bags re...
متن کاملSurvival of Escherichia Coli Serotype O157:H7 in Water and in Bottom-Shore Sediments
Survival of a single strain E. coli serotype O157:H7, isolated from milk in Poland, was examined in water environment (water, bottom-shore sediments and in muddy water over sediments) at 6°C and 24°C. Pathogenic bacteria were not detected (direct plating method) in water within 32 and 51 days of incubation at 6°C and within 21 and 32 days of incubation at 24°C (except water from one of the rive...
متن کاملSurvival of Escherichia coli O157:H7 and Listeria monocytogenes in Doogh, A Traditional Iranian Dairy Beverage
Background: Unlike industrially production, Iranian traditional doogh are not pasteurized after production. Hence, possible contamination with different pathogenic bacteria may occur during production or post-production of traditional doogh. The aim of the present study was to monitor the behavior of Escherichia coli O157:H7 and Listeria monocytogenes in traditional Iranian doogh at different t...
متن کاملOccurrence of Chitinolytic Bacteria in Water and Bottom Sediment of Eutrophic Lakes in Iławskie Lake District
A study was carried out on the occurrence of chitinolytic bacteria inhabiting surface water, water above the sediment and bottom sediments of lakes: Jeziorak, Jeziorak Maty and Tynwald. The greatest amounts of them were found in demersal water and in bottom sediment surface stratum. However, the percentage share of chitinolytic bacteria proved greater in deep water (9.35%) than in bottom sedime...
متن کاملSurvival of Escherichia coli in Freshwater
Experiments on the survival of Escherichia coli were conducted in the water of man-made Zegrzynski Reservoir. The aim of this study was to evaluate how selected biocenotic factors (predation, coliphage infection, presence of autochthonic microflora and nutrient conditions) affect this process. We observed residual living cells of E. coli up to about thirty days of the investigation. We found th...
