Abstract

Shiga toxin (stx), produced by enterohemorrhagic Escherichia coli (EHEC) or Shigella, causes hemolytic uremic syndrome (HUS) in humans. EHEC-mediated illnesses are recommended to treat by immune supportive strategies, instead of antibiotic therapy. Widely used probiotic Lactobacillus casei produces many bioactive metabolites, i.e., conjugated linoleic acids (CLAs) which have potential to educate host immunity and control EHEC growth and expression of its virulence genes. In this study, it was found that total metabolites of L. casei exerted a protective effect on Gb3 receptor containing mammalian cells against stx exposure.
