Legionella bacteria can be a serious threat to public safety, but a partnership of Vitens, TNO and the Kennemerland Regional Laboratory in the Netherlands has developed a method of quick detection.

The Legionella chip works with biomarkers based on DNA technology, and can identify the presence of the harmful bacteria in four to six hours — down from the previous 12 days.

It can detect the difference between harmless and disease-causing Legionella bacteria. As well as increasing speed and accuracy, this technology significantly reduces testing costs.
