[Reservoirs and transmission of Pseudomonas aeruginosa in intensive care unit].

OBJECTIVE: The authors had for aim to study reservoirs and transmission of Pseudomonas aeruginosa in an intensive care unit. DESIGN: 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.

[Endocarditis due to Pasteurella sp. Two cases].

Human pasteurellosis is, in general, a locoregional infection due to contact with an animal. Systemic infections are rare and endocarditis is exceptionally described. The authors report two new cases of endocarditis due to Pasteurella spp, they then review 29 other published cases. Pasteurella spp. endocarditis presents as an acute form in 64% of cases and affects the aortic as often as the mitral valves. Contact with an animal is documented in 65% of cases. Pasteurella multocida is the most frequent species in this infection. The total death rate is 40% and can reach 57% of cases in case of immunodepression. The bad prognosis of this infection, justifies an early diagnosis and a rapid and adapted but not yet consensual medicosurgical treatment.

Severe infection caused by Stomatococcus mucilaginosus in a neutropenic patient: case report and review of the literature.

A 24-year-old female, in neutropenic phase after chemotherapy for acute myelogenous leukemia (on day 15) was admitted in intensive care unit for infectious pneumonia. Two strains of Stomatococcus mucilaginosus were isolated from peripheral blood cultures. No microorganisms were yielded from bronchoalveolar lavage. Patient's condition improved with prompt instigation of effective antibiotic therapy. This was the first case of septicemia and pneumonia, due to Stomatococcus mucilaginosus, in our unit. Only 26 cases occurring in neutropenic patients with underlying hematologic malignancies were reported in the literature and among these, only five cases with pneumonia were described. The complications of this normal inhabitant of the human oral cavity can be serious and fatal: septic shock, meningitis, acute respiratory distress syndrome. This study illustrate the possible virulence of Stomatococcus mucilaginosus in neutropenic patients.
