As one of the world's leading supplier of diagnostic culture media, Oxoid is committed to the development of products that provide faster and easier bacterial identifications for clinical laboratories.

The use of innovative chromogenic substrates within the Oxoid Chromogenic Media range provides clearly visible answers on a single culture plate and reduces or eliminates the need for further confirmatory testing.

Chromogenic technology detects specific enzyme activity in target organisms - quickly and accurately. These enzymes cleave a colourless substrate in the medium, releasing colour molecules within the colonies of interest and allowing them to be clearly seen, differentiated and counted.

The extensive selection of Oxoid Chromogenic Media available to clinical laboratories includes:

• Oxoid Chromogenic Candida Agar (product code: CM1002) for the rapid isolation, differentiation and identification of clinically important Candida species.
  
• Oxoid Chromogenic Salmonella Agar (CM1007) for the identification of Salmonella species and selective differentiation from other Enterobacteriaceae.
  
• Oxoid Chromogenic UTI and Chromogenic UTI (Clear) media (product codes CM0949/CM1050) for the presumptive identification and differentiation of all the main micro-organisms that cause urinary tract infections.
  
• Oxoid SMAC Agar + BCIG (product code CM0981) for the detection of E. coli O157 and differentiation from other E. coli.
