Chromogenic culture media provide a rapid and accurate method of isolating and enumerating target micro-organisms based on the detection of specific enzyme activities.

Not only do chromogenic media enable faster detection of specific micro-organisms compared with classical culture media, they also improve sensitivity and can reduce the need for subculture or confirmatory tests.

Lab M®'s Harlequin™ range of chromogenic media includes products for the isolation of Listeria species, Salmonella, Escherichia coli and Enterobacter (formerly Cronobacter) sakazakii.
