Transcriptional analysis of genes encoding Shiga toxin 2 and its variants in Escherichia coli.

ABSTRACT: Six of 37 non-O157 Escherichia coli strains possessing Shiga toxin (Stx) 2 gene variant stx(2d) or stx(2e) secreted no detectable Stx. These isolates produced significantly less stx mRNA than Stx2d, Stx2e, Stx2c, or Stx2 secretors did. Standard screening procedures miss a significant subset of E. coli harboring stx(2) variants.
