HardyCHROM™ Salmonella, an effective chromogenic screen of all Salmonella spp., 15x100mm plate, order by the package of 10, by Hardy Diagnostics. This product has a short shelf life and ships from our California warehouse only.

HardyCHROM™ Salmonella is a differential medium that facilitates the isolation and differentiation of Salmonella spp. from other members of the family Enterobacteriaceae.

This medium utilizes the ability of Salmonella spp. to produce acid from propylene glycol. This characteristic is used in conjunction with a chromogenic indicator to differentiate Salmonella spp. form Proteus spp. and other Enterobacteriaceae.

Salmonella spp., including S.typhi and S.paratyphi A, produce pink to magenta colonies as a result of propylene glycol utilization. Members of the family Enterobacteriaceae produce blue, blue-green, white, or colorless colonies, while gram-positive bacteria and non-glucose fermenting bacteria will be inhibited.


HardyCHROM™ Salmonella facilitates the isolation and differentiation of Salmonella spp. from other members of the family Enterobacteriaceae. Peptones in the medium supply the necessary nutrients. Selective agents inhibit the growth of gram-positive organisms. Artificial substrates (chromogens) are broken down by specific microbial enzymes which release insoluble colored compounds. Salmonella species break down only one of the chromogens and will produce deep pink to magenta colored colonies. Bacteria other than Salmonella spp. may break down the other chromogenic substrates and produce blue colonies. If none of the substrates are utilized, natural or white colored colonies will be present.

  • See the Instructions For Use (IFU) below (under Technical Information) for the complete procedure with color photos.

  • 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 detection methods.

  • We offer a handy bench-top flip chart to help you interpret the colors of all our chromogenic media. Please call us to receive your copy! (800) 266-2222.

  • We believe in good patient care, just like you do. Look to Hardy and experience "a culture of service."

    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.
