Outbreak of gut colonization by Pseudomonas aeruginosa in immunocompromised children undergoing total digestive decontamination: analysis by pulsed-field electrophoresis.

摘要: We analyzed an outbreak of gut colonization by Pseudomonas aeruginosa occurring in intensive care hematology unit using conventional typing methods and pulsed-field electrophoresis. In October November 1989, the feces four immunocompromised children undergoing total digestive decontamination were colonized P. aeruginosa. Ten isolates obtained from flora pure culture. Retrospective investigations found that one isolate stools patients was already present at high counts 6 months before outbreak. This patient had been discharged May 1989 readmitted concomitantly with Only electrophoresis could demonstrate a single epidemic strain fecal children. probably brought into chronic carriage. Images
