Pseudomonas aeruginosa

Need oxygen and multi-resistant

Pseudomonas aeruginosa is a Gram negative bacillus which is incapable of fermenting1 sugars. It is therefore characterized by growth strictly in the presence of oxygen. It is found to be extremely present in the environment and poses a problem in hospitals because of its significant resistance to commonly used antibiotics.

To the hospital

Pseudomonas aeruginosa is the leading cause of hospital acquired pneumonia. It is frequently also found in various other hospital-acquired infections, such as complicated urinary tract or catheter infections as well as secondary wound infections.

All green

Pseudomonas aeruginosa typically exhibits a green tint due to the production of a pigment called pyoverdin. There are many other species of Pseudomonas including, for example, Pseudomonas entomophila which, as its name suggests, is an insect pathogen, thanks to a toxin. Other Pseudomonas are known as plant pathogens or as simple, harmless microbes found in the environment.
