| Popis: | A prospective study was undertaken to determine the source of Pseudomonas cepacia colonization and infection that had affected ventilated patients in an Intensive Care Unit (ICU) for three years. Thirty-eight patients undergoing mechanical ventilation were enrolled during a six-week period. Samples were taken from patients, ventilator circuits and the environment for culture. P. cepacia was isolated from the condensate formed in the ventilator circuit and the source of the contamination was shown to be the temperature sensor. Ribotyping of representative strains of P. cepacia performed with two endonucleases, Eco RI and Pvu II, confirmed the homogeneity of the isolates from patients and ventilator circuits. A modification of the procedure for disinfection of the temperature sensors resulted in the eradication of P. cepacia from the ICU. |
