Pseudomonaden - Pseudomonas aeruginosa

Pseudomonas aeruginosa is a bacterium that develops a protective colloid (slime) out of metabolized substances against disinfectants.   These protective colloids sometimes cannot be sufficiently oxidized due to the free chlorine. With growth optimum at 37°C, swimming pools have the perfect conditions for reproduction. Insufficiently or incorrectly rinsed filters, tile grouts and pipelines often make the perfect reproduction conditions for pseudomonades.   Pseudomonas aeruginosa can cause swim water related infections (for example skin infections, outside ear infections and UTI’s). This mucus bacteria is also a dominant organism for staphylococci and atypical micro bacteria and, in Europe, is not allowed to be detectable in 100ml. Regular filter and system cleaning as well as running effective flocculation are important preventive measures to minimize risks.
