Single-Cell Analysis of Viable Legionella

Single-Cell Analysis of Viable Legionella

rqmicro reagents capture and stain all viable Legionella cells in the sample. They also detect viable but non-culturable (VBNC) cells that the cultivation method cannot detect.

Rapid Legionella test

2 hours 5 min from sample to results

Standard workflow for 4 samples in parallel takes less than 4 minutes hands-on-time per sample and a total hands-on time of 15 minutes.

On-Site and In-Lab

On-Site or In-Lab

Reliable and quantitative results from point of use or in lab testing. Results are always immediately available on the cloud.

Legionella bacteria

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.
