HardyCHROM CRE Agar - a chromogenic medium for detection of carbapenemase in Enterobacteriaceae, 10 pack - by Hardy Diagnostics

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. The test is performed with a mixed population of microorganisms from a laboratory sample. HardyCHROM™ CRE Agar is not intended for use in the identification of colonization with carbapenem-resistant bacteria to aid in the prevention and control of such bacteria in healthcare settings. 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. 

The selective components in HardyCHROM™ CRE Agar are agents that inhibit the growth of yeast, gram-positive bacteria and gram-negative carbapenem-sensitive bacteria (e.g., a carbapenem). The presence of chromogens allows the differentiation of gram-negative bacteria that produce carbapenemase. The colonies of those bacteria that release products when they use the chromogens as a substrate source appear colored.

Klebsiella, Enterobacter, and Serratia spp. produce large, dark blue colonies. .

Hardy Diagnostics was the first company to introduce chromogenic prepared media to the United States in 1996. You can expect Hardy Diagnostics to be the leading innovator in chromogenic plating methods.

This media is to be stored and incubated in the dark. If you have a light in your refrigerator, incubator, or you leave the media exposed to light on the bench top, Hardy Diagnostics offers free Blok-Boxes. Blok-Box is a reusable cardboard box that holds one sleeve of ten petri plates.
