Antiserum reagent OK O pool Big Six

for serologyEscherichia coli

SSI Diagnostica offers an E. coli OK O pool that detects the STEC serogroups O26, O45, O103, O111, O121, and O145 by slide agglutination. In addition to continued testing for E.coli O157:H7, new regulations in the United States now require the meat industry to monitor for six non-O157 Shiga toxin-producing E.coli (STEC) serogroups. The regulation requires testing for the so called “Big Six” STEC (O26, O45, O103, O111, O121, and O145) as these serotypes have been most frequently associated with E. coli outbreaks of food-borne illnesses worldwide. If the products test positive they will be prevented from entering commerce. The Big Six STEC strains cause outbreaks of hemorrhagic colitis (bloody diarrhea) and hemolytic uremic syndrome (kidney failure). In case there is an additional requirement related to the detection of the virulence genes (Vtx1, Vtx2, eae, estA (porcine and human), eltA, and ipaH) we recommend the use of the E.coli DEC PCR kit.
