Pseudomonas aeruginosa in Swimming Pool Water: Evidences and Perspectives for a New Control Strategy

View Article: PubMed Central - PubMed

ABSTRACT

Pseudomonas aeruginosa is frequently isolated in swimming pool settings. Nine recreational and rehabilitative swimming pools were monitored according to the local legislation. The presence of P. aeruginosa was correlated to chlorine concentration. The ability of the isolates to form a biofilm on plastic materials was also investigated. In 59.5% of the samples, microbial contamination exceeded the threshold values. P. aeruginosa was isolated in 50.8% of these samples. The presence of P. aeruginosa was not correlated with free or total chlorine amount (R2 < 0.1). All the isolates were moderate- to strong-forming biofilm (Optical Density O.D.570 range 0.7–1.2). To control biofilm formation and P. aeruginosa colonization, Quantum FreeBioEnergy© (QFBE, FreeBioEnergy, Brisighella, Italy), has been applied with encouraging preliminary results. It is a new, promising control strategy based on the change of an electromagnetic field which is responsible for the proliferation of some microorganisms involved in biofilm formation, such as P. aeruginosa.

Mentions: Certain materials such as silver, aluminum, and glass, with a particular shape and arrangement in space are able to yield electromagnetic signals to water particles from a distance of several meters, using natural fields (Earth’s magnetic field, cosmic radiations, and electromagnetic motions typical of the ionosphere) as environmental carriers. With this new configuration, the water can interact with immersed biological structures, transforming them from a suitable environment for growing bacteria to one not suitable for bacterial species, and these properties can be maintained for long distances and a long time. Therefore, QFBE is classifiable as an “informational technology” (Figure 1).
