What is Pseudomonas Aeruginosa?
Pseudomonas aeruginosa is a type of bacteria commonly found in the environment. It is classified as a Hospital Acquired Infection (HAI) and can cause infections in the blood, lungs, or other parts of the body after surgery. Pseudomonas bacteria are constantly finding new ways to avoid the effects of the antibiotics used to treat the infections they cause. In 2017, multidrug-resistant According to the 2019 AR Threats Report 
, Pseudomonas aeruginosa caused an estimated 32,600 infections among hospitalized patients and 2,700 estimated deaths in the United States.
Preventing the Spread of Pseudomonas Aeruginosa
Outbreaks from Pseudomonas aeruginosa have been traced to a variety of sources , including respiratory therapy equipment, endoscopes, contaminated mattresses, disinfectants, contaminated water supplies, IV solutions, sinks, taps, mops, and environmental sources such as pools used for physical therapy or hydrotherapy.
It is also constantly reintroduced into the hospital environment on fruits, plants, vegetables, and patients transferred from other facilities. Spread occurs from patient to patient on the hands of hospital personnel, by direct patient contact with contaminated reservoirs, and by the ingestion of contaminated foods and water.
The CDC lists the following practices to avoid spreading this P. aeruginosa in healthcare facilities:
- Careful attention to regular hand hygiene, particularly, before and after caring for wounds or touching a medical device
- Daily cleaning of patient rooms and shared equipment
- A water management program that is effective in limiting opportunistic pathogens from growing and spreading in each healthcare facility
Enhance the Above Protection with Germicidal UV Disinfection
The disinfection of patient rooms and medical devices can be enhanced with Germicidal Ultraviolet Disinfection. The UV-C dosage listed below can inactivate the Pseudomonas aeruginosa in many applications, including hospitals and healthcare facilities. Our products use STER-L-RAY® Germicidal UV-C Lamps producing ultraviolet wavelengths at 254 nanometers, the region of germicidal effectiveness most destructive to harmful microorganisms including P. aeruginosa.
Water supply and pool disinfection procedures can also benefit from UV-C Disinfection. Our Germicidal Ultraviolet Water Purifiers designed for commercial and industrial use are effective in limiting many opportunistic pathogens that can spread throughout hospitals and healthcare facilities.
Pseudomonas Aeruginosa: Classification & UV-C Dose for Inactivation
| Organism: | Alternate Name: | Type: | Disease: | UV Dose*: |
|---|---|---|---|---|
| Pseudomonas Aeruginosa (Lab Strain) | P. Aeruginosa | Bacteria | — | 3.90 mJ/cm2 |
| Pseudomonas Aeruginosa (Environ. Strain) | P. Aeruginosa | Bacteria | — | 10.50 mJ/cm2 |

People at High Risk for a Pseudomonas Aeruginosa Infection
According to the CDC , people with the highest risk for P. aeruginosa infection include patients in hospitals, especially those:
- On breathing machines (ventilators)
- With devices such as catheters
- With wounds from surgery or burns
