Pseudomonas aeruginosa are a type of bacteria commonly found in water sources and healthcare environments, and known to cause serious infections in the blood, lungs (pneumonia), or other parts of the body after surgery.
Pseudomonas aeruginosa bacteria are particularly likely to become resistant (no longer respond) to several types of antibiotics (multidrug-resistant). Carbapenem-resistant Pseudomonas aeruginosa (CRPA) are resistant to last-resort antibiotics called carbapenems.
CRPA can spread from patient to patient in healthcare settings like hospitals and nursing homes. There are limited antibiotic treatment options for patients who develop infections caused by CRPA. Patients with CRPA infections have significantly worse outcomes than patients with non-carbapenem-resistant infections.
