GeneDisc® Technologies Legionella

For the rapid quantification, detectionand identification of Legionella spp., L. pneumophila and L. pneumophila serogroup 1

Legionellosis are infections caused by bacteria of the genus Legionella, generally by aerosol inhalation. With over 95,000 human cases reported per year, it is one of the most frequent causes of waterborne disease.

Legionella species are capable of colonizing artificial water systems and equipment containing water, making this pathogen a major issue for:

  • Industries where cooling towers can generate a wide dispersion of bacteria;
  • Hospitals and care facilities where contaminated hot tap or shower waters are potential sources of Legionella outbreak and can effect weakened patients;
  • Public-access buildings, such as spas and swimming pools, where aerosol dispersion is common;
  • Fountains in public space.

Pall GeneDisc Technologies provides complete solutions to water system network managers for real time Legionella risk management.


GeneDisc System Benefits

Rapid —While culture methods require up to 12 days to obtain results, Pall’s GeneDisc method allows a quantification of Legionella in as fast as 2 hours.

Unambiguous —The PCR specificity allows a direct and accurate identification of Legionella sp.

Easy to use —Matrix specific protocols are designed for routine use and validated from sample to result.

Modular —System modularity fits your throughput needs: up to 88 samples for quantification and 96 samples for detection and identification can be simultaneously analyzed.


A Solution Designed for Water Network Management

Reduce down-time —Shorter time to results enables reactive surveillance preventing delayed intervention on water networks and system closures.

Implement appropriate and effective disinfection measures —Mapping water system networks with the GeneDisc system identifies and targets contaminated pipework and water points.

In line with NF T 90-471 and ISO/TS 12869 —NF VALIDATION certified method against both standards.

Quantify Legionella spp. and Legionella pneumophila simultaneously —GeneDisc Plate Legionella DUO enables combined detection and quantification of both Legionella spp. and Legionella pneumophila using the same sample preparation and without any additional hands-on time.

Direct detection and identify the LegionellaGeneDisc Plate Legionella ID enables rapid source screening and the identification of Legionella spp., L. pneumo and L. pneumophila Serogroup 1.
