Immunochromatography Test Kit Checlear O-157

Checlear O-157 is the immunochromatography test kit which is developed for easy and rapid detection of E.coli O-157 in food. Detection limited of E.coliO-157 by this method was 5 × 104cells/mL. Compare to the result of culture method (official method), data of Checlear O-157 correspond with culture method (official method). But Checlear O-157 showed cross reaction with some strains (Citrobacter freundii, Salmonella urbana, Bacillus cereus) other than E.coli. Considering those results, Checlear O-157 will be useful in preliminary screening of E.coli O157 in food.
