Clinical Significance

Shiga toxin producing Escherichia coli causes foodborne and waterborne diarrheal disease worldwide which, if left undiagnosed, can progress to hemorrhagic colitis and/or hemolytic uremic syndrome. Since certain treatments and medications can increase the risk of HUS, prompt detection is necessary to prevent outbreaks and secondary tranmission. Shiga Toxin Quick Chek can detect STEC present in fecal samples or culture, regardless of the serotype or other virulence factors.
