Pseudomonas aeruginosa is a gram-negative rod that grows in aerobic conditions. It is a multidrug-resistant pathogen associated with hospital-acquired infections, ventilator-associated pneumonia, sepsis, and urinary tract infections. This bacterium is considered an opportunistic organism because it can cause very serious infections in those with preexisting conditions – most notably cystic fibrosis and immunocompromised patients. When P. aeruginosa colonizes critical body organisms such as the lungs, kidneys, and urinary tract, the infection can be fatal without antibiotic intervention. It is very important to administer treatment based on laboratory sensitivities. A sample should be collected from the infection site, cultured, identified, and tested against many different antibiotic classes for sensitivity.
Pseudomonas aeruginosa is a citrate, catalase, and oxidase positive organism. It also produces indophenol oxidase, which renders a positive oxidase test result – distinguishing P. aeruginosa from other gram-negative rods. On sheep blood agar, P. aeruginosa has a metallic, blue-green look, caused by the pigments pyocyanin and pyoverdin. It also produces a grape or aged wine odor. It can be found in soil, water, skin flora, and man-made environments.
