HardyCHROM™ UTI, a chromogenic medium for all urinary pathogens and other uses, 15x100mm plate

One plate does it all!

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.

There are a number of organisms routinely isolated from urinary tract infections (UTI). Most UTIs are caused by Escherichia coli alone, or in combination with other organisms. The most frequently isolated species produce characteristic enzymes. Chromogenic substrates (chromogens) incorporated into HardyCHROM™ UTI produce different colored compounds when they are degraded by specific microbial enzymes. Thus, HardyCHROM™ UTI can be used for the cultivation and differentiation of various groups of organisms with only a minimum number of confirmatory tests.

Features and Benefits:
E. coli produces large magenta
colonies (confirmatory, no further
testing required)
Enterococcus faecalis/faecium
produces small, turquoise-colored
colonies
Pseudomonas spp. produce light
yellow/green, translucent colonies.
Klebsiella, Enterobacter, and Serratia
spp. produce large, deep blue colonies
Staphylococcus saprophyticus
produces opaque, pink colonies
Candida spp. produces small, white,
moist colonies
Proteus, Morganella, and Providencia
spp. produce clear to light yellow
colonies with a diffuse golden-orange
halo in the medium
Staphylococcus aureus produces
opaque, white-colored colonies
Citrobacter spp. produce
dark blue colonies often
with a rose halo in the
surrounding media


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.
