Pseudomonas aeruginosa - Definition

Ask a question


Pseudomonas aeruginosa is a bacteria found everywhere in nature, particularly in hot, humid environments. This bacteria usually only rarely attacks humans, but it can become pathogenic (responsible for a disease) in certain situations. It is extremely resistant to antibiotics, and is notably responsible for a growing number of hospital-acquired infections, also called nosocomial infections. This germ primarily attacks immunocompromised patients, in other words those whose immune systems are weakened, and can be the cause of many infections, notably urinary, pulmonary, or postoperative in nature, essentially in those in fragile condition. Treatment consists of antibiotics.
