Enterotoxigenic E. coli (ETEC) strains produce heat-stable toxin (ST) and heat-labile toxin (LT), while enterohemorrhagic E. coli (EHEC) strains produce Shiga toxins (stx genes), leading to severe complications like bloody diarrhea and hemolytic uremic syndrome (HUS). This evidence concerns the gene LTA and hemolytic-uremic syndrome.
