A revolutionary technology for tagging exclusively culturable Legionella pneumophila of all serogroups

Our Technology


Assimilation of a specific L. pneumophila Ulosonic Acid

Based on a CNRS patented innovation. 

Legio EZ solutions use an innovative technology1, protected by 3 patent families, which combines :

  • Culturing on selective growth media of the sample to be analyzed
  • Assimilation only by the L. pneumophila of a modified sugar
  • Development of this modified ulosonic acid present after the assimilation in the part O-antigenic of lipopolysaccharide from L. pneumophila, through a reaction based on chemistry « click » for realizing colorimetric and enzymic reaction.
