For detection and differentiation of pathogenic Yersinia enterocolitica HIGH SPECIFICITY OF THE MAUVE COLOUR 1 Clear differentiation of Yersinia among background flora Background flora, such as Citrobacter, often has a Yersinia-like red aspect on CIN agar which generate a heavy routine workload on false positive results. Thanks to CHROMagarTM Y.enterocolitica, this unnecessary workload will be eliminated as only pathogenic Yersinia enterocolitica colonies will grow mauve. 2 Colourful differentiation of pathogenic among non pathogenic Yersinia enterocolitica In traditional culture media like CIN agar, pathogenic and non-pathogenic biotypes have the same aspect. On CHROMagarTM Y.enterocolitica, the pathogenic biotypes grow in a distinctive mauve colour, differentiated at a glance, from the non pathogenic which will grow metallic blue. HIGH SELECTIVITY: REDUCTION OF BACKGROUND FLORA Background flora is dramatically reduced on CHROMagarTM Y.enterocolitica allowing an easy reading of the plates. The laboratory will concentrate its efforts and resources only on suspect colonies that have a real potential of pathogenicity.
