Abstract: Bacteria can grow or re-grow in distribution systems
of drinking water. In fact, potable water is a major source of
some bacteria colonization, for example L. pneumophila and E
coli. etc. The L. pneumophila in potable water can replicate
rapidly and increase in virulence. Given the low infectious dose
of pathogenic bacteria, the presence of even a single bacterium
in potable water may pose a serious health risk. Therefore,
sensitive and rapid detection of bacteria in water is critical.
However, the current definitive method for the detection of
bacteria is the culture of the organism,
