Loss of vtx Genes after the First Subcultivation Step of Verocytotoxigenic Escherichia coli O157 and Non-O157 during Isolation from Naturally Contaminated Fecal Samples
Verocytotoxins VT1 and VT2,produced by Verocytotoxigenic Escherichia coli (VTEC), are encoded on temperate bacteriophages. Several studies reported the loss of the vtx genes after multiple subcultivation steps or long preservation. The objective of this study was to determine if the loss of the vero...
