Although several other Legionella species exist, some of which such as Legionella longbeachae and L. bozemanii can be pathogenic, these infections are much rarer and are much less associated with large-scale outbreaks. If your building has water installations such as spas, water heaters, safety showers, misters or aerosol-generating air conditioning systems, note that it may be appropriate to add Legionella analysis to your risk identification and management program. If you have a water-cooled cooling tower installation (WCTI), you will be subject to the regulations governing the transmission of information to the R\u00e9gie du b\u00e2timent du Qu\u00e9bec(RBQ)2. Legionella bacilli, microscope Lab&#8217;EAU-AIR-SOL has a rigorous team of qualified microbiologists and chemists for your analysis needs. We are also authorized to produce ITRE maintenance programs for Legionella prevention. We also offer consulting services for risk analysis of other types of systems that may be the source of Legionella exposure.
