While the precise method of transmission of epidemic strains of P. More worryingly, some of these epidemic strains are associated with increased morbidity and treatment burden when compared to non-epidemic strains. aeruginosa infection by patients with CF is usually from the environment, but recent studies have demonstrated patient to patient transmission of certain strains of P. aeruginosa infection and increased mortality. A number of studies have also demonstrated an association between chronic P. Most studies would suggest that 70–80% of patients are infected during the teenage years. Once the patients lung becomes chronically infected the bacteria change to a mucoid phenotype and form biofilms. aeruginosa infection in patients with CF the bacteria are not usually mucoid and can be cleared with aggressive antibiotic treatment. aeruginosa infection in patients with CF can occur at any age. aeruginosa from tap water follows contamination of the taps rather than the mains water supply. aeruginosa can be detected when opening taps. The bacterium is frequently found in environmental reservoirs, such as the drains of hospital ward wash basins and aerosols containing P. It is ubiquitous within the environment and is particularly isolated from moist areas such as soil and water. aeruginosa is a facultative anaerobe which may allow it to survive within the relatively hypoxic lungs of patients with CF. Although classified as an aerobic organism P. The organism is a Gram-negative, non-fermentative, aerobic bacillus belonging to the family Pseudomonadaceae. aeruginosa is the most common and clinically important pathogen in patients with CF. This causes plugging of the sub-mucosal glands and impairment of mucociliary clearance leading to infection, inflammation, and tissue damage resulting in bronchiectasis and a predisposition to infection with pathogens such as Pseudomonas aeruginosa. Lack of CFTR function results in reduced fluid secretion and excessive fluid absorption, with a net effect of producing a thickening of the mucous component of the airway surface liquid. The condition is due to mutations in the cystic fibrosis transmembrane conductance regulator (CFTR). Warming and drying the air within clinical areas and avoidance of humidification devices may also be beneficial in reducing the risk of cross-infection.Ĭystic fibrosis (CF) is an inherited multi-system disorder characterised by chronic airway infection, pancreatic insufficiency, elevated sweat chloride concentration, impaired fertility and hepatobiliary disease. Environmental factors also appear to influence bacterial survival. aeruginosa infection who are more likely to be infected with mucoid strains may help reduce the risk of cross-infection.

This would suggest that segregating individuals free of P. aeruginosa were able to survive within the aerosols, but strains expressing a mucoid phenotype had a survival advantage. Both epidemic and non-epidemic strains of P. Within the aerosols it was adversely affected by an increase in air temperature. Survival was effected by the solution used for aerosol generation. aeruginosa within artificially generated aerosols. This study was designed to examine the survival of P. aeruginosa by patients with CF is usually from the environment, but recent studies have demonstrated patient to patient transmission of certain epidemic strains, possibly via an airborne route. These are readily available at pond specialist aquatic centres and of course internet.Cystic fibrosis (CF) is an inherited multi-system disorder characterised by chronic airway infection with pathogens such as Pseudomonas aeruginosa.Īcquisition of P. There are pond vacuums which will hoover up what is left in the bottom. The pump / syphoning will be able to remove most of the water, but not all. Though this system does not need any excavation that is not to say it cannot be dug into the ground or incorporated into decking or flagging, but you will have to consider how you might empty the tanks for winter or for maintenance, cleaning etc. With potted plants and garden ornaments, the whole system can be landscaped in in a few hours a fraction of the time and thousands of pounds cheaper conventional system. We include covers and filters to assist in the job of keeping the water clean.Īs mentioned before there is no need for any excavations as this system is completely self-contained it can simply be placed onto your patio or decking filled plugged in and turned on. The pump and laminar flow nozzle are in the (90% recycled plastic) pump tank, the laminar jet fires into the receiver tank which is connected to the pump tank giving a circulation of water, this action aerates the water which helps avoid stagnation.
