title: [The presence of E. coli O 157 in the surface and underground waters].
abstract: Escherichia coli O 157 is the G(-) bacteria, and belongs to the enterohaemorrhagic E. coli (EHEC). E. coli O 157 is a bacteria that is a common inhabitant of the ruminants, particularly cattle. These bacteria are expelled with animal excretions and can contaminate the soil. They are transferred by rain and melting snow into surface and underground water. The strain E. coli O 157 is dangerous for human, because of toxins, known as Shiga. In this study E. coli O 157 in the samples of surface and underground water was determined. It was shown that E. coli O 157 appears in natural waters very rare.
