Why detect Legionella on time?

Legionellosis, a disease caused by Legionella bacteria is on the rise around the world. Legionella bacteria, naturally occurring in water and soil, frequently colonize artificial water systems in residential buildings or in industry. Transmitted through aerosol into human lungs, Legionella can spread and cause Legionellosis (also: Legionnaires disease), which has a high mortality rate. The early detection and prevention of Legionella growth in water systems is the key to stop the increase of cases around the world.

The established detection method for Legionella is very inaccurate and delivers results only after 10 days. Fast and actionable data is however crucial to effectively manage the safety of water systems.

We therefore set out to develop rapid and quantitative microbiological methods that provide users with easy and reliable tools to analyze water on-site.
