PSEUDOMONAS AERUGINOSA
AEROBE

WHAT IS PSEUDOMONAS AERUGINOSA?

Pseudomonas aeruginosa is a gram-negative bacillus found in humid environments and, therefore, some cosmetic products with a high water content are susceptible to hosting these bacteria, allowing them to proliferate and infect end users. More severe infections occur in people who are already hospitalized with another illness or condition, or people who have a weak immune system.

Infections caused by this bacterium are characterized by inflammations. If this infection occurs in the lungs or other vital organs, it can prove to be fatal. Diseases caused by it are pneumonia, urinary tract infections, and gastrointestinal infections.

COMMON SYMPTOMS OF PSEUDOMONAS AERUGINOSA

Infections in the skin tend to be less severe than infections that occur in the blood or lungs. Specific symptoms depend on where the infection occurs:

1. BLOOD

A bacterial infection of the blood is called bacteremia. A blood infection is one of the most severe infections caused by pseudomonas. 

Symptoms:

  • Fever
  • Chills
  • Fatigue
  • Muscle & Joint pain

Bacteremia with pseudomonas can also cause very low blood pressure, known as hemodynamic shock, which can lead to failure of other organs including the heart, kidneys, and liver.

2. LUNGS

Infection of the lungs is called pneumonia. Symptoms include:

  • chills
  • fever
  • cough with or without sputum production
  • difficulty breathing

3. SKINS

When this bacterium infects the skin, it most often affects the hair follicles. This is called folliculitis. Symptoms may include:

  • redness of the skin
  • abscess formation in the skin
  • draining wounds

4. EAR

An external ear canal infection may sometimes be caused by pseudomonas and result in “swimmer’s ear.” Symptoms may include:

  • swelling
  • ear pain
  • itching inside the ear
  • discharge from the ear
  • difficulty hearing

5. EYE

Symptoms of an eye infection may include:

  • inflammation
  • pus
  • pain
  • swelling
  • redness
  • impaired vision

Pseudomonas infections can be very aggressive, particularly infections in the lungs or skin.
