Chromogenic salmonella medium suits food samples

Harlequin Salmonella ABC from Lab M is a chromogenic medium suitable for culturing organisms from both clinical and food samples.

This medium differentiates Salmonella spp from other members of the enterobacteriaciae by their ability to produce alpha-galactosidase in the absence of beta-galactosidase, using a dual chromogen system for visualisation.

Clinical samples may be streaked direct to the medium, or plated following selective enrichment in selenite broth.

For food samples, streaking for single colonies follows pre-enrichment and selective enrichment.

Lab M's range of salmonella products is designed to enable selection of the most suitable medium for any circumstances - from pre-enrichment to isolation.

It includes the company's inhibitor-free Buffered Peptone Water, which supports the recovery of sublethally damaged organisms prior to further enrichment in media such as Rappaport Vassiliadis Broth, Mueller Kaufmann Tetrathionate Novobiocin Broth (MKTTn) and Selenite Broth.

As well as Harlequin Salmonella ABC chromogenic medium for selective isolation, Lab M offers traditional media such as XLD Agar and Brilliant Green Agar.
