A Microgen Bioproducts product story

Microgen Bioproducts has improved the Aoac-Ri validated Microgen Listeria-ID to make the system a user-friendly and cost-effective method of identifying Listeria species.

The Microgen Listeria-ID is a biochemical identification system that consists of 10 sugar fermentation tests, Aesculin hydrolysis and an improved micro-haemolysis reaction.

 

Microgen Bioproducts has improved the Aoac-Ri validated Microgen Listeria-ID.

The system does not require any reagent additions and reduces laboratory costs while utilising substrates that conform to all international standards.

Microgen Listeria-ID has been improved to provide an easy-to-read method of differentiating haemolytic and non-haemolytic Listeria spp.

Haemolytic and non-haemolytic Listeria spp have traditionally been differentiated by the sub-culture from selective medium to sheep blood agar for the detection of haemolytic activity or by performing the variable, complex and difficult to interpret Camp test.

The inclusion of a sensitive and stable micro-haemolysis in the Microgen Listeria-ID allows for the easy interpretation of haemolysin production by haemolytic Listeria spp; if an organism produces haemolysin, the red blood cells will rapidly be lysed, releasing cellular contents forming a red/brown solution.

If an organism does not produce haemolysin the red blood cells will remain intact and form a distinct red pellet with clear supernatant, indicating a negative result.

As with all the Microgen-ID range, the Microgen Identification System Software, provides laboratories with an accurate identification package.
