  • Commercial vehicle wash - case study

    Problem: A large city local authority identified significant infection risks at one of its waste depots, where its fleet of dust carts were cleaned using a commercial vehicle wash on a daily basis. This vehicle wash recycles the water, and was infected with water-borne bacteria. The aerosol droplets sprayed over the dust carts were a serious infection risk to employees and the ...

  • Cooling tower legionella pneumophila study CDC

    Abstract Since the late 1970s, there have been many small and large outbreaks of Legionnaires’ disease. Most of these outbreaks have been traced to either cooling tower water systems or potable water systems. Although the bacteria most often associated with Legionnair’s disease, Legionella pneumophila, is present in many waater systems, outbreaks are usually a result of ...

  • Antibiotic susceptibility of Legionella strains isolated from public water sources in Macau and Guangzhou

    The purpose of this study was to investigate the susceptibility of waterborne strains of Legionella to eight antimicrobials commonly used in legionellosis therapy. The minimum inhibitory concentrations (MICs) of 66 environmental Legionella strains, isolated from fountains and cooling towers of public facilities (hotels, schools, and shopping malls) in Macau and Guangzhou, ...

  • BioSense a Biofilm Monitor and Controller

    Abstract Biofilms (slime) can form on virtually every nonshedding surface, in a nonsterile aqueous environment i.e. anywhere where a water source is present; such as cooling/heating systems, swimming areas and in drinking water purification. These Biofilms can cause a myriad of problems including; harbouring harmful bacteria such as Legionella, inducing corrosion, and reducing ...

  • A pcr-based method for monitoring legionella pneumophila in water samples detects viable but noncultivable legionellae that can recover their cultivability

    Legionella pneumophila is the causative agent of Legionnaires' disease. This bacterium is ubiquitous in aqueous environments and uses amoebae as an intracellular replicative niche. Real-time PCR has been developed for rapid detection of Legionella DNA in water samples. In addition to culturable bacteria, this method may also detect dead and ...

  • Legionnaires is an Air Quality Risk

    The recent Bronx, NY outbreak of Legionnaires infections is a grim reminder of the deadliness of this strain of pneumonia. Like many of the outbreaks, cooling towers caused this one. Twenty have been identified but the search is still going on. Over 120 people were infected and 12 have died. Tragically it affects the most vulnerable people–people with one or more immune system deficiencies. ...

  • Cooling tower case study

    Cooling towers have always been difficult to control. Algae grow in the cooling tower itself and on the grids used. In addition to micro-organisms and biofilm, they reduce the efficiency of the cooling tower. Furthermore the risk of spreading Legionella is a serous factor to be reckoned with. Many of the traditional methods to fight algae are either insufficient, cumbersome, environmentally ...

  • Does the risk of Legionnaire’s Disease rise when there’s lead in your water?

    Ongoing monitoring shows that lead levels in Flint, Michigan’s water are dropping and getting closer to meeting federal safety standards. That’s some much-needed positive news for the community. But there’s still work to be done. Now, researchers are starting to check residential hot water heaters in Flint homes for Legionella. Legionella grows best in warm water and hot water ...

  • 6 Things You Should Know About Legionella

    Just last August, about 120 people in the South Bronx were infected with Legionnaires’ Disease and 12 people died. At the time, up to 5 cooling towers in the area tested positive for Legionella, a fatal bacteria that grows in warm, damp environments and can spread once contaminated water has become aerosolized and the vapor is inhaled. In this post, we’ll be discussing where ...
