The research focus entails the development of detection and identification methods, as well as a study of the fate (survival) of water-borne pathogens. Detection, typing and identification methods for Campylobacter and Vibrio cholerae in biofilms as well as surface and drinking water sources are developed. The prevalence of bacterial pathogens in biofilms associated with drinking water is investigated, as is the survival of pathogens in fesh water sediments.
