Harlequin™ chromogenic media
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 HarlequinTM range of chromogenic media includes products for the isolation of Listeria species, Salmonellae, Escherichia coli and Enterobacter (formerly Cronobacter) sakazakii.
