E. coli O157 Latex Kit

2 Minute Latex Agglutination Test

For the Culture Confirmation of E. coli O157

  • Ideal for testing food, clinical, environmental and veterinary samples. 
  • Results  in 2 minutes
  • Use directly from selective plates
  • Simple to use latex test


Microgen E. coli O157 is an easy-to-use one step, latex identification kit which gives results in under two minutes and specifically identifies E. coli O157 directly from the selective plate, even in mixed culture.

The conventional method for identification of E. coli O157:H7 utilises specific antisera in a standard agglutination test.  However, this method and other commercially available latex tests have been shown to suffer from cross reactions with other enteric organisms such as E. hermanii, which antigenically and biochemically resembles  E. coli O157, resulting in false positive results.  Microgen E. coli O157 contains a test latex which has been sensitised with E. coli O157   specific antibodies, that are prepared by absorption with potentially cross reacting strains.  

Microgen E. coli O157 has demonstrated no cross reactions when tested against a panel of 161 E. coli O157 ‘O’ serotypes and 56 ‘H’ serotypes, and shows strong specific agglutination.

Microgen E. coli O157 gives strong and specific results within two minutes and comes   complete with a control latex which can be easily compared with test results to confirm non-specific reactions.
