Production of the Subtilase AB <sub>5</sub> Cytotoxin by Shiga Toxin-Negative <i>Escherichia coli</i>

26 Nov 2009

Abstract excerpt

The subtilase cytotoxin (SubAB) is an AB(5) toxin described in certain Shiga toxin (Stx)-producing Escherichia coli (STEC) strains that usually lack the locus for enterocyte effacement (LEE). We report for the first time the production of SubAB by two Stx-negative E. coli strains, isolated from unrelated cases of childhood diarrhea. The characterization of the SubAB-coding genes showed a 90% nucleotide sequence...
