Pseudomonas: Symptoms, Causes, and Treatment

What is Pseudomonas?

A pseudomonas infection is caused by a bacterium of the Genus Pseudomonas. The bacteria are found widely in the environment, such as in soil, water, and plants. They usually do not cause infections in healthy people. It is more likely that people will contract a severe infection if they are already hospitalized with another illness or condition, or if they have a weak immune system. These are fairly common microorganisms involved in infections acquired in a hospital setting.

How Does Pseudomonas Infection Spread?

It lives in the environment and can be spread to people in healthcare settings when they are exposed to water or soil that is contaminated with these microorganisms. Resistant strains of the bacteria can also spread in healthcare settings from one person to another through contaminated hands, equipment, or surfaces.

Signs and Symptoms?

Specific symptoms depend on where the infection occurs. Watch out for the following:


A blood infection is one of the most severe infections caused by this condition. Symptoms may include:


Infection of the lungs is called pneumonia. Symptoms include:

  • Fever and chills
  • Cough with or without sputum production
  • Difficulty breathing


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

  • Abscess formation in the skin
  • Redness of the skin
  • Draining wounds


An external ear canal infection may sometimes be caused by this condition. Symptoms may include:

  • Ear pain
  • Itching inside the air
  • Difficulty hearing
  • Discharge from the ear
  • Swelling


Symptoms of an eye infection may include:

  • Inflammation
  • Pus and pain
  • Swelling and redness
  • Impaired vision

What Causes Pseudomonas? 

These infections are caused by a free-living bacterium from the Genus Pseudomonas. They are commonly found in moist areas such as soil and water. The bacteria can be spread in hospitals via the hands of healthcare workers, or by clinic equipment that is not properly cleaned. These infections are considered opportunistic infections as it affects a person’s immune system that is already impaired. Your risks of getting the condition increase if you:

  • Have burn wounds
  • Are receiving chemotherapy for cancer
  • Have cystic fibrosis
  • Have HIV or AIDS
  • You are using a mechanical ventilator or catheter
  • Are undergoing an invasive procedure, like a surgery

Treatment and Management of Pseudomonas

These infections are treated with antibiotics. Unfortunately, many infections are becoming more difficult to treat. Antibiotics are no match for these bacteria, as they have developed the ability to adapt to their environment and overcome them. This is called antibiotic resistance.

The increase in antibiotic resistance has made treating infections much more challenging. Oftentimes, it develops resistance to multiple types of antibiotics and can even develop resistance during treatment. Your medical provider must select the right antibiotic and other medications for you. To do this, your doctor may recommend further laboratory testing to determine which medications work best.

How to Diagnose Pseudomonas?

A doctor might ask about recent activities that might help diagnose the infection, like swimming or using a hot tub. They will also carry out a physical examination or take samples of blood or fluid from the affected area to confirm a diagnosis. It may also be necessary to conduct laboratory tests to determine the best course of treatment since there are different types of bacteria.

Medications Used for Pseudomonas Infection

Ciprofloxacin Dexamethasone Otic. It has high potency and rapid bactericidal activity and a long post-antibiotic effect on certain bacterial infections. It exhibits a low frequency of mutational resistance. Ciprofloxacin is in a class of medications called quinolone antibiotics. Dexamethasone is in a class of medications called corticosteroids.

The combination of ciprofloxacin and dexamethasone works by killing the bacteria that cause infection and reducing swelling. Before using this medication ensure to tell your doctor about your allergies and other conditions. Inform your doctor about the prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take.
