Infection control plays an exceedingly important role in preventing the spread of antimicrobial-resistant bacteria within hospitals. Since Ps. aeruginosa is a hydrophilic organism, it can thrive in moist environments in the hospital and be disseminated from a common source. Common source outbreaks linked to contaminated hydrotherapy water have been documented on burn and surgical wards. Additional outbreaks have been linked to contaminated endoscopes (Hancock and Speert, 2000).
Ps. aeruginosa can be transiently carried on the hands of medical and nursing personnel resulting in the spread of infection among patients. Principles of good infection control such as careful hand washing and barrier precautions should be utilized when dealing with patients with antibiotic-resistant bacteria. Immunization against Ps. aeruginosa would be a strategy for preventing acquisition and spread of antibiotic-resistant strains. Whereas several different vaccine strategies have been considered and tested, none has yet entered clinical use
