Shiga toxins are a family of related toxins with two major groups, Stx1 and Stx2, expressed by genes considered to be part of the genome of lambdoid prophages.[1] The toxins are named after Kiyoshi Shiga, who first described the bacterial origin of dysentery caused by Shigella dysenteriae.[2] Shiga-like toxin (SLT) is a historical term for similar or identical toxins produced by Escherichia coli.[3] The most common sources for Shiga toxin are the bacteria S. dysenteriae and some serotypes of Escherichia coli (shigatoxigenic or STEC), which include serotypes O157:H7, and O104:H4.[4][5]
