Towards more accurate detection of pathogenic Gram-positive bacteria in waters

Medically important bacteria can persist in surface waters longer than was previously thought, by activating specific survival strategies and, thus, may represent a further threat to human health, in that they are non-detectable by the traditional culture methods currently used for the evaluation of microbiological quality. Combining microbial physiology, microbial biochemistry, microbial genetics, microbial ecology and molecular biology techniques allow us to achieve more accurate detection of human pathogens located in natural environments external to the human body.
