The bacteria pseudomonas aeruginosa is what causes pseudomonas aeruginosa infection. It is frequently present in the environment, such as in soil and water. It can be transferred from infected materials, hands, and tools to individuals in hospital environments. In certain people, it can result in life-threatening illnesses. Even some healthy individuals have strains of it developing on their skin in moist areas of their bodies, such as the vaginal region or armpits.

It’s possible you won’t become sick from it if you’re in better health. Others merely get a minor skin rash or an infection of the ears or eyes. But pseudomonas can result in a serious infection if you’re already sick or have a compromised immune system. It can be fatal in persons with cancer, cystic fibrosis, or burns. That is one of the most common reasons why patients get infections while hospitalized.


The site of the Pseudomonas aeruginosa affects the symptoms. Any portion of your body, including your lungs, blood, urinary tract, stomach, or tendons, might become infected by a pseudomonas aeruginosa infection. Wounds, burns, and pressure sores can potentially get infected.

Locations where infections arise and potential symptoms include:

  • Eyes. Redness, swelling, pain
  • Ears. Discharge and pain
  • Wounds. Discharge
  • Lungs. Congestion and severe cough; pneumonia
  • Digestive tract. Diarrhea or headache
  • Joints or bones. Joint swelling and pain

A severe pseudomonas infection is frequently accompanied by a fever.


Your doctor will take a specimen from your blood or another bodily fluid and submit it to a lab for testing if they believe you have a Pseudomonas aeruginosa infection. The outcomes might also enable them to select the drugs that effectively treat the infection.


Your doctor may suggest a course of antibiotics if you have a minor infection. This medication may come in the form of a cream, ear or eye drops, and oral pills, depending on where your infection is. An IV will be used to provide weeks’ worth of antibiotics if the infection is severe. 

These infections can be challenging to treat since each pseudomonas bacteria is subtly different from the others, and strains are constantly evolving. You may frequently need to take multiple antibiotic types. Bacteriophages, viruses that infect bacteria, have recently been discovered by researchers to be helpful in the treatment of Pseudomonas aeruginosa infections.
