Pseudomonas (Aeruginosa)
Pseudomonads are a type of bacteria that are present everywhere in nature. However Pseudomonas Aeruginosa is a dangerous, pathogenic species. This bacteria is opportunistic, meaning it will attack any tissue that is weakened or even a little bit damaged. It can survive on an incredibly diverse number of nutrients, it’s even been found growing on soap, antiseptics and in bottled mineral water. Because of its hardy structure, treatment is very difficult; many antibiotics simply won’t kill it.
How does it spread?
The Pseudomonas bacteria are covered with a biofilm (a layer of slime) that protects it from conventional antibiotics, and cleaning products/procedures. As a result it is incredibly easy to pick up the bacteria from contaminated surfaces, and contaminate food in a ‘clean’ food prep area.
Symptoms
Pseudomonas can infect any area of the body, but they most commonly attack the respiratory tract (the mouth and nose) causing bacterial pneumonia. They may also cause ear infections, and infect burn wounds, which may be seen as a rash or dermatitis.
People most at risk
Pseudomonas will attack anyone with a weakened immune system, such as patients already in hospital, the elderly and the very young. Those with burns or wounds are especially at risk. One in ten HAI is caused by Pseudomonas bacteria.
Best prevention
- Hand hygiene is essential. Use a hand sanitiser and wash hands thoroughly and frequently, especially after using the toilet, before handling food or coming into contact with and infected person or their belongings.
- Hygienically clean toilet, bathroom, and kitchen surfaces. In particular handles and switches.
- Be particularly careful around 'at risk' groups.
- Disinfect and cover any broken skin with a clean dressing.
- Avoid touching any medical devices, i.e. catheters.
