HardyCHROM™ is Hardy Diagnostics’ line of chromogenic, selective and differential culture media, recommended for use in primary cultivation and isolation of microorganisms. Hardy Diagnostics was the first company to introduce chromogenic media to the United States in 1996. We have a dozen chromogenic media with our line continuously growing.


A chromogenic media plate (HardyCHROM SS NoPro Agar) showing growths of Salmonella enterica

HardyCHROM™ SS NoPro (no-Proteus) Agar is recommended for the selective isolation and differentiation of Salmonella and Shigella spp. from stool. HardyCHROM™ SS NoPro Agar is intended as a primary screening tool to distinguish Salmonella and Shigella spp. from non-pathogenic enteric bacteria based on colony color, while inhibiting the growth and characteristic swarming of Proteus spp. The enhanced inhibition of Proteus reduces the expense involved in working up non-pathogens that could mimic enteric pathogens.

Chromogenic agar (HardyCHROM CRE Agar) growing kiebsella pneumoniae colonies

HardyCHROM™ CRE Agar is a selective and differential chromogenic medium, containing a carbapenem, intended for use as a plating technique to obtain a pure culture of gram-negative bacteria that produce carbapenemase. HardyCHROM™ CRE Agar is not intended to diagnose infections by carbapenem-resistant bacteria, guide or monitor treatment for infections, or provide susceptibility results to a carbapenem. Sub-culturing is necessary for microorganism identification, susceptibility testing, and epidemiological typing.

HardyCHROM™ Group A Strep Agar

HardyCHROM™ Group A Strep Agar is our new chromogenic medium allows for an easy-to-read and straight forward selective cultivation and differential isolation of Group A Streptococcus (S. pyogenes) or GAS. GAS can be differentiated on this medium based on colony color (red, red-brown, or red-orange colonies) among other non-GAS bacteria that are part of the throat flora (blue, clear, or white colonies) after 24 hours of incubation.

Catalog no. G337

HardyCHROM™ UTI is a differential culture medium that facilitates the isolation and differentiation of urinary tract pathogens, including gram-negative and gram-positive bacteria. The development of various colors, due to chromogenic substances in the media, allows for the differentiation of microorganisms from the primary set-up of a urine specimen.

Catalog no. G313

HardyCHROM™ Candida

HardyCHROM™ Candida is a selective medium recommended for the isolation and identification of yeasts. This medium also allows for the differentiation of C. albicans , C. tropicalis and C. krusei based on differences in colony morphology and color. This medium facilitates the detection of mixed yeast cultures.

Catalog no. G301

  • Easy one-step process! Adding tiles is no longer necessary.
  • Easy read-out. Development of any orange to red color indicates a positive result.
  • Lower cost when compared to the LIM Broth method.
  • Can be used with liquid and gel-based transport systems.
  • Negative cultures from Strep B Carrot Broth should be subcultured to detect weakly or non-hemolytic strains of GBS.
  • Carrot Broth One Step is available in multiple formats that work on many automated inoculating machines.
