Mansour JD, Robson JA, Arndt CW, Schulte TH (1985) Detection of Escherichia coli in blood using flow cytometry. Cytometry 6 :186-190


A rapid method for the detection of Escherichia coli in blood has been developed. The method employs blood cell lysis, staining of bacteria with ethidium bromide, and detection of stained bacteria using flow cytometry. The detection protocol requires less than 2 h sample handling time and is not dependent on bacterial growth. This method has been applied to human donor blood specimens seeded with various E. coli concentrations and to two rabbit model systems. Bacterial detection is evident from the in vitro human blood studies at levels of 10 E. coli/ml and from in vivo rabbit model studies at less than 100 E. coli/ml.

Flow cytometry, using fluorescein-bound specific antibodies and propidium iodide, was shown to be effective in detecting Legionella spp. in cooling tower waters. The procedure was quicker and less labor intensive than fluorescent microscopy. The use of these procedures also identified qualitative differences, perhaps related to infectivity, in Legionella populations.
