Abstract: Shiga toxin-producing Escherichia coli (STEC) are serious foodborne pathogens,which can cause severe human diseases such as hemorrhagic colitis,hemolytic uremic syndrome,etc,cattle,sheep and other ruminants are major hosts that cause lead to disease in humans. This paper summarizes the epidemiological situation of Shiga toxin-producing E. coli,and make a review on the research progress of virulence factors that locate on Shiga toxin-producing E. coli chromosome and virulence plasmid.

Key words: Shiga toxin-producing Escherichia coli(STEC); epidemiology; pathogenic factor
