Pathogenicity of Biofilm Bacteria

Abstract:There is a paucity of information concerning any link between the microorganisms commonly found in biofilms of drinking water systems and their impacts on human health. For bacteria, culture-based techniques detect only a limited number of the total microorganisms associated with biofilms. The possibility of unknown opportunistic pathogens occurring in potable water and biofilms within drinking water systems still exists but it is unlikely that pathogenic microorganisms will be found using individual in vivo culture-based techniques or by screening large numbers of isolates using the currently available in vitro virulence tests. A combination of molecular-based techniques and animal-exposure studies will provide the information necessary to fully characterize the pathogenicity of microorganisms commonly associated with biofilms.
