Legionella and bacteria analysis

4see has many years experience in the testing for and isolation of Legionella species and Legionella pneumophilia in water samples.

Customers are informed of presumptive positives at any stage throughout the 10 day incubation. Confirmation and enumeration is completed after the full 10 day incubation period.

Legionellae are a group of environmental bacteria which have adapted to living in water and therefore water systems. Legionellae are found naturally in rivers, lakes and reservoirs and they enter man made systems via mains water where given the right conditions of temperature and nutrients they will grow.

Legionellosis is the illness which can be caused by susceptible people inhaling water aerosols containing Legionellae bacteria.

Sources commonly creating aerosols which might contain the bacteria are cooling towers, spa-baths and shower heads. This means that any trade, business or premises that uses or stores water could be the source of Legionella pneumophila and the cause of an outbreak of Legionnaires disease.

Assessment of water samples from vulnerable sources is important to demonstrate due diligence and the efficiency of water treatment put in place to comply with legislation which protects the public and employees.
