Lab M's product range for the isolation of Cronobacter sakazakii now includes both broth and chromogenic media.
In addition to the Harlequin Cronobacter sakazakii isolation medium, the company offers Cronobacter sakazakii enrichment broth.
This product series facilitates the testing regimes recommended for C.
sakazakii isolation under ISO/TS 22964:2006(E).
Cronobacter sakazakii Enrichment Broth (CSEB) is the secondary enrichment broth as currently recommended for the isolation of C.
sakazakii from milk and milk products.
Based on lauryl sulphate tryptose broth, it has added sodium chloride for extra selectivity against competing organisms.
The antibiotic vancomycin is also added to inhibit Gram-positive organisms such as Staphylococccus aureus, which may be able grow in this medium.
Harlequin Cronobacter sakazakii isolation medium (Harlequin CSIM) uses chromogenic technology for rapid detection.
The combination of sodium desoxycholate, crystal violet and elevated incubation temperature results in a selective and specific medium that produces green-coloured colonies of the target bacterium.
Chromogenic media reduce the need for subculture or confirmatory tests.
