Pseudomonas aeruginosa is a bacteria that can cause infections in many parts of the body. It survives in most environments and is very resistant to antibiotics. Infections caused by P. aeruginosa can be life-threatening, but all have the potential to be treated.
While P. aeruginosa rarely makes healthy people sick, it is an opportunistic pathogen. This means it can be dangerous for people with a weakened immune response. If you catch an infection while in a hospital, it will most likely bePseudomonas aeruginosa.
