What is Pseudomonas aeruginosa?

The bacterium Pseudomonas aeruginosa is the most significant and longest-known bacterium of the genus Pseudomonas in human medicine. It occurs both on surfaces and in water, and colonizes the gastrointestinal tract of humans and animals. Many of the Pseudomonas aeruginosa strains have developed resistance to common antibiotics.

How is pseudomonas aeruginosa transmitted?

The pathogen is usually found in wet areas, for example the tap outlet, washbasins, toilets, dishwashers, bath water and drinking water can all be contaminated with the germ. A small dose is enough to infect humans. The Pseudomonas aeruginosa bacterium can be transmitted directly from human to human and indirectly through contaminated objects and surfaces.

What are symptoms of the disease?

Infection with the germ can lead to pneumonia, wound and urinary tract infections. In the worst case, life-threatening sepsis (blood poisoning) can occur. Hospital patients, elderly people and infants are particularly at risk of infection.

Significance for infections in hospitals and in the outpatient sector

In clinical settings, bacterial infection often leads to catheter-associated urinary tract infections or lower respiratory tract infections in respiratory patients. The treatment of infections is difficult. This is often only possible through a combination of various antibiotics, as many strains (particularly those transmitted in a medical facility) are resistant to many antibiotics.

Survival time of pathogens on inanimate surfaces

6 hours to 16 months, on dry soils: 5 weeks

Disinfectant effectiveness for prevention

The necessary spectrum of activity against Pseudomonas aeruginosa is: bactericidal
