What is a Pseudomonas infection?
Pseudomonas infection is caused by strains of bacteria found widely in the environment; the most common type causing infections in humans is called Pseudomonas aeruginosa.
What types of infections does Pseudomonas aeruginosa cause?
Serious Pseudomonas infections usually occur in people in the hospital and/or with weakened immune systems. Infections of the blood, pneumonia, and infections following surgery can lead to severe illness and death in these people.
However, healthy people can also develop mild illnesses with Pseudomonas aeruginosa, especially after exposure to water. Ear infections, especially in children, and more generalized skin rashes may occur after exposure to inadequately chlorinated hot tubs or swimming pools. Eye infections have occasionally been reported in persons using extended-wear contact lenses.
Who is at risk for infection?
Patients in hospitals, especially those on breathing machines, those with devices such as catheters, and patients with wounds from surgery or from burns are potentially at risk for serious, life-threatening infections.
How is Pseudomonas aeruginosa spread?
In hospitals, where the most serious infections occur, Pseudomonas can be spread on the hands of healthcare workers or by equipment that gets contaminated and is not properly cleaned.
How can Pseudomonas infections be prevented?
In the hospital, careful attention to routine infection control practices, especially hand hygiene and environmental cleaning, can substantially lower the risk of infection.
Outside the hospital, avoid hot tubs or pools that may be poorly maintained, and keep contact lenses, equipment, and solutions from becoming contaminated.
How are Pseudomonas infections treated?
Pseudomonas infections are generally treated with antibiotics. Unfortunately, in hospitalized patients, Pseudomonas infections, like those caused by many other hospital bacteria, are becoming more difficult to treat because of increasing antibiotic resistance. Selecting the right antibiotic usually requires that a specimen from a patient be sent to a laboratory to test to see which antibiotics might still be effective for treating the infection.
What is the CDC doing to monitor, prevent, and/or help treat infections?
The CDC conducts surveillance, prevention, and outreach activities to help prevent infections and to ensure that serious infections stay susceptible to commonly-used antibiotics and do not become resistant and hard to treat. CDC employees work closely with state and local health departments, Federal agencies, healthcare providers, and consumers of healthcare to help educate people about Pseudomonas infections, and antibiotic resistance, and to encourage prevention activities and healthy behaviors to prevent antibiotic resistance.
