[Determination of the viability of Escherichia coli M17 by its respiratory activity]

The possibility of the determination of the number of viable E. coli M17 in Colibacterin by the rate of oxygen consumption, based on measuring the slow fluorescence of these bacteria, has been studied. The direct correlation between the number of live E. coli and their respiratory activity in the standard sample of Colibacterin has been established. The method of measuring the oxygen consumption rate is recommended as an additional rapid method for the control of the content of live E. coli in the process of the manufacture and storage of the preparation.
