Occurrence of Bacteria and Coli Bacteriophages as Potential Indicators of Fecal Pollution of Vistula River and Zegrze Reservoir
نویسنده
چکیده
This paper presents a sanitary state estimation of Zegrze man-made reservoir and Vistula river using typical bacterial factors. The aim of this study was to introduce the possibility of the use of coli bacteriophages as potential indicators of fecal polluted waters. Zegrze Reservoir, as well as the examined Vistula sector, belong to microbiologically contaminated waters. Especially in the summer period they are rich in coli-type and E.coli bacteria. The changes in E.coli numbers were correlated with bacteria phage numbers.

متن کاملBacteriological Studies of Water and Bottom Sediments of the Vistula River between Wyszogród and Toruń
This paper deals with the sanitary conditions of the water and bottom sediments in the Lower Vistula river, between Wyszogród and Toruń. The contamination extent of the water and bottom sediments by easily decomposable organic matter and substances of faecal origin have been indirectly estimated by determining the total number of heterotrophic bacteria (TVC 20oC) and the occurrence of the faeca...
