Pseudomonas aeruginosa: guidance, data and analysis

The characteristics, diagnosis, management and epidemiology of Pseudomonas aeruginosa.


  1. Epidemiology

Pseudomonas aeruginosa is a Gram-negative bacterium often found in soil and ground water. P. aeruginosa is an opportunistic pathogen and it rarely affects healthy individuals. It can cause a wide range of infections, particularly in those with a weakened immune system eg cancer patients, newborns and people with severe burns, diabetes mellitus or cystic fibrosis.

P. aeruginosa infections are sometimes associated with contact with contaminated water. In hospitals, the organism can contaminate devices that are left inside the body, such as respiratory equipment and catheters. P. aeruginosa is resistant to many commonly-used antibiotics.
