Research with quantitative DNA methods
No pathogenic nontuberculous mycobacteria in drinking water
In foreign countries, specific pathogenic bacteria are sometimes detected in chlorinated drinking water that can make people with a weakened immune systems ill. Specifically, this concerns some species of nontuberculous mycobacteria. KWR conducts research, within the water sector’s joint research programme (BTO), to determine whether these bacteria are also present in drinking water in the Netherlands.
Water samples from various pumping stations and drinking water tap points are analysed using DNA methods, including three quantitative methods developed specifically for several species of pathogenic nontuberculous mycobacteria. The species found in Dutch drinking water are chiefly those that are not pathogenic. The three species of pathogenic mycobacteria have not been detected at all. Drinking water therefore does not play an important role in nontuberculous mycobacterial infections in people with a weakened immune systems in the Netherlands.
