Legionella Kits

rqmicro developed highly specific kits to simplify, improve and
accelerate the detection of Legionella.

Quantify Legionella in less than 2 hours

rqmicro developed highly specific kits to simplify, improve and accelerate the detection of Legionella in water.

It allows the quantification of intact Legionella cells within approximately 2 hours. Importantly, the kit also detects viable but non-culturable cells (VBNC), which do not grow on culture media but can still be infectious. With the established cultivation method, VBNC cannot be detected. This is one of the major reason why it is currently difficult to manage water hygiene and why dangerous Legionella are “suddenly” appearing in water systems.

The result, the number of intact Legionella cells in 100ml, makes it easy to monitor water systems, measure the success of treatments and detect potential growth of Legionella.

Legionella kits

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 Legionnaires disease, which has a mortality rate of 10%. 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.
