Pseudomonas has an antiphagocytic polysaccharide slime layer and many strains produce pigments, some which are fluorescent. Pseudomonas produces localized infections following surgery or burns. Localized infections can lead to generalized, and occasionally fatal, bacteremia. Pseudomonas is also responsible for a number of nosocomial infections including urinary tract infections following catheterization, pneumonia resulting from contaminated respirators, and eye and ear infections. Pseudomonas can be found in the soil, in water, or on vegetation.
Diagnosis is very difficult.
Pseudomonas can be easily isolated on blood agar. They often give off a fruity odor and some may produce fluorescent pigments. P. aeruginosa grows well at 42 . Proper isolation and topical therapy of burn patients, good aseptic technique and the careful cleaning and sterilization of instruments are important. 1997-2001 Douglas F. Fix.
