Infections with Pseudomonas paucimobilis: report of four cases and review.
Pseudomonas paucimobilis (formerly CDC group IIK, biotype 1) is a strictly aerobic, nonfermenting, oxidase- and catalase-positive, gram-negative bacillus that is widely distributed in water and soil. Its name derives from the difficulty encountered in demonstrating its motility, even in liquid media. This microorganism is responsible for two types of infection in humans: sporadic or community-acquired infections, probably of endogenous or environmental origin (bacteremia, meningitis, urinary tract infection, and wound infection); and outbreaks of nosocomial infection associated with the contamination of sterile fluids employed in hospitals. We present four cases of infection caused by P. paucimobilis (two of bacteremia, one of leg ulcer infection, and one of cervical adenitis). The majority of infections produced by P. paucimobilis have a good prognosis; no deaths related to this entity have been reported in the literature. The published results of susceptibility tests suggest that the aminoglycosides (either alone or in combination with a beta-lactam antibiotic) or the quinolone may be the agents of choice in the treatment of these infections.
