Developed to improve the isolation and identification of a variety of microorganisms, Lab M’s Harlequin chromogenic media can help eliminate or reduce the need for subculture and confirmatory biochemical tests. The Harlequin range now includes media for Listeria monocytogenes isolation, the enumeration of coliforms, and E. coli O157:H7 and Salmonella species isolation. Chromogenic media represent one of the most significant advances in microbiological culture in recent years. They provide a rapid, accurate means of isolating and enumerating target microorganisms based on the detection of specific enzyme activities. Lab M’s Harlequin Listeria Chromogenic Agar (Agosti & Ottaviani formulation) was the first chromogenic dehydrated Listeria medium as specified by ISO 11290. Designed for food industry applications, it can be used as the primary isolation medium for L. monocytogenes.
