E. coli ELISA kits are assays designed to detect markers expressed by the bacterium, Escherichia coli. A Gram-negative facultative anaerobe, it is commonly found in the gut microbiome of healthy humans. However, some serotypes, such as O157, are pathogenic. E. coli colonization and production of toxins and virulence factors can cause food poisoning, meningitis, and infections in the gastrointestinal and urinary tracts. E. coli is a popular host organism for recombinant DNA technology. Visit the supplier page for more information about detection target, range, and reactivity.
