NEOGEN Harlequin Chromogenic Agar for Salmonella Esterase (CASE), 5 kg
Supplier: NEOGEN 700004801
CASE is a selective chromogenic agar for the detection of Salmonella that can be used as part of the ISO 6579-1:2017 workflow. It is not intended for use in the diagnosis of disease or other conditions in humans.CASE utilizes a dual chromogenic system to differentiate between Salmonella and non-target organisms that grow on the agar. The first chromogen is a target for esterase activity present in all Salmonella species, and results in blue/green colonies. The second chromogen is a target for ß-glucosidase activity, present in non-target organisms that are able to grow on the agar and also possess esterase activity. Utilization of the second chromogen masks the presentation of the first, resulting in black colonies in non-Salmonella organisms. All other organisms are either inhibited or grow colorless on the agar.For more information visit https://www.neogen.com/solutions/Microbiology/harlequin-chromogenic-agar-salmonella-esterase
