Identification of a Shiga-toxin type I variant containing an IS1203-like element, from Shiga-toxin producing Escherichia coli O157:H7.

abstract：:When bacterial cells are subjected to stress, cellular and population characteristics can change significantly. Rapid acquisition of these properties of cells in their native physiological state is necessary in order to precisely interpret their survival modes. The multiparametric analytical capability of flow cytomet...
