Surveillance of intensive care units: a priority for reducing healthcare associated infections
Impaired immune defences, invasive procedures and low compliance to infection prevention measures favour the transmission of pathogens in... read more
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.
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.
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.
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.
