title: Evaluation of bacterial contamination in blood processing.
abstract: In the routine deglycerolization of frozen red blood cells, a bottle of solution intended as a final wash (0.8% NaCl, 0.2% dextrose) was found to be abnormally colored and slightly turbid. Close inspection revealed a small crack in the base of the bottle. A pure growth of Klebsiella pneumoniae was cultured. The rabbit pyrogen test on the solution was positive using 2.5 mul as was the limulus amebocyte lysate (LAL) test at a dilution of 1:10-5 for endotoxin. Studies of the growth of this organism are described and the clinical implications are discussed.
