'''''E. coli'' O157:H7''' is a virulent strain of ''[[E. coli]]'' with multiple genes coding for virulence. It expresses a Shiga like [[A/B5 toxin]] that behaves in a manner similar ricin within the body. It also codes for special [[Pili]] known as H7 pili which enables it to attach to the Jejunum, an area of the GI tract that E. coli typically does not attach to.
