Pseudomonas fluorescens bacteremia from blood transfusion

摘要: Abstract In October 1980, two units of blood contaminated with Pseudomonas fluorescens caused septic tranfusion reactions in recipients at a Chicago hospital; one patient died. Both had been purchased from the same center. Investigation center and other hospitals it supplied revealed another fatal case P. sepsis that occurred year earlier. Despite extensive environmental culturing center, source was not identified. However, comparison interval between collection administration noncontaminated indicated prolonged storage risk factor may have clustering cases hospital. Laboratory studies showed small inocula proliferated refrigerated fresh whole reached 10 6 to 7 colonyforming per milliliter seven days after incubation. These data suggest be an important for development transfusion-related sepsis.
