Persistence and Spatial Patterns of Recombinant Escherichia coli in Drinking Water Biofilms

摘要

1. Pathogens in drinking water sources can cause disease outbreak in the populationserved, and drinking water distribution systems are vulnerable to accidental anddeliberate contamination with pathogens.2.Microorganisms attach themselves to surfaces of conduits in drinking waterdistribution systems forming biofilms on pipes.3.Biofilms create a favorable environment for the potential retention and growth ofpathogens as the pathogens have been shown to be less susceptible to disinfectingagents once inside biofilms. 1,2,54.These pathogens can survive by competing with the existing organisms in the biofilmfor nutrients.5.It is important to study pathogen survival potential in a biofilm as they can be
