E. coli O157:H7 Cromogenic Agar Base is used for the detection of E.coli O157:H7. E. coli O157:H7 has become a widespread public health issue as it is responsible for hemorrhagic colitis, characterized by a bleeding diarrhea with acute abdominal pain. E.coli O157:H7 produce several cytotoxins, neurotoxins, and enterotoxins, including Shiga toxin. Incorrect antibiotic treatment may increase the risk of haemolytic uraemic syndrome development, a potentially fatal complication of this form of colitis. E. coli O157:H7 has a bovine reservoir, infection can occur after ingestion of undercooked beef or unpasteurized milk. The organism can also be transmitted by the fecal-oral route. Peptone Mixture provides nitrogen, vitamins, minerals and amino acids essential for growth. Chromogenic mixture allows to easily detect the presence of E.coli O157:H7 by colony coloration that grows pale pink. Potassium tellurite and cefixime are highly selective for E. coli O157:H7 and inhibit most contaminating bacteria including other E.coli strains and coliforms. Bacteriological agar is the solidifying agent.
