Patented chromogenic substrates offer rapid, reliable culture & identification


The innovative CHROMID® range of chromogenic media is the easy way to rapidly and reliably detect and identify microorganisms. Specific chromogenic substrates are included in the agar along with peptones and – if needed – antibiotics. The substrate is hydrolyzed when it comes in contact with the bacteria or yeast, resulting in specific coloration for clear identification. Even mixed cultures are more identifiable than with conventional media. The intensity and specificity of the colors of CHROMID® make results clear to see.

  • Easy-to-read results in 18-24 hours
  • Reliably identify pathogens with specific colors
  • Detect mixed culture for better isolation of pathogens
  • Sensitive and specific
  • Cost-effective pre-plated media


Experience leads to quality

As a pioneer in chromogenic technology, bioMérieux’s long experience ensures you get high quality chromogenic media. Our culture of innovation means we regularly bring you new CHROMID® products and services to help meet your constantly-evolving challenges in the microbiology laboratory. For example, healthcare associated infections (HAI) are a serious and growing concern, posing major patient-care and economic challenges for healthcare systems. To help in the fight against HAI, we have developed a range of CHROMID media designed specifically to detect the microorganisms involved in HAI.


Be clear on compatibility with Certificate of Compatibility


A Certificate of Compatibility is available for each CHROMID® chromogenic medium. This validated document clearly shows the medium’s compatibility with complementary product ranges, including ID/AST reagents. Easily ensuring compatibility helps you meet your accreditation requirements and reduces the number of validations you have to perform.

  • Compatibility is clear and easy to ensure
  • Make accreditation easier
