Abstract

The gram-negative bacteria P. aeruginosa has occurred as a severe hospital infection. These bacteria is common in hospitals and is a commensal bacterium found on the skin surface, in the nose, in the upper respiratory system, and in the intestines of up to 40% of healthy people. This percentage climbs in direct proportion to the length of a patient's stay in the hospital. In the absence of topical therapy, 70% of patients' burn sites are cultured by the third week, indicating that P. aeruginosa has established itself as a dominant member of the flora. Cases of nosocomial pneumonia account for 16% of all Cases of nosocomial pneumonia. 12 % P. aeruginosa is responsible for 12 percent of hospital-acquired urinary tract infections, 8% of surgical wound infections, and 10% of bloodstream infections. It's also to responsible for septicemia, which accounts for 30% of all deaths and has high fatality rates in burn units.
