OBJECTIVE The authors had for aim to study reservoirs and transmission of Pseudomonas aeruginosa in an intensive care unit. METHODS A 6-month prospective descriptive study was made on water samples, samples from hands of health care workers, and clinical samples. P. aeruginosa strains were compared by pulsed-field gel electrophoresis. RESULTS Among the 211 patients hospitalized during the study, 14 (6.6%) were infected by P. aeruginosa. Out of 494 water samples, 80 were contaminated by P. aeruginosa. The regularly disinfected water taps were more rarely contaminated than the others (P<10(-5)). Out of 140 hand samples, one showed contamination from an infected patient. CONCLUSIONS aeruginosa cross transmission was observed during this study. We should follow strict hygienic precautions such as wearing gloves and performing thorough alcoholic rub disinfection. Water taps are often contaminated and require regular disinfection.

D004197 Disease Reservoirs Animate or inanimate sources which normally harbor disease-causing organisms and thus serve as potential sources of disease outbreaks. Reservoirs are distinguished from vectors (DISEASE VECTORS) and carriers, which are agents of disease transmission rather than continuing sources of potential disease outbreaks. Humans may serve both as disease reservoirs and carriers.
