HardyCHROM UTI is a non-selective chromogenic medium recommended for the cultivation, differentiation and enumuration of urinary tract pathogens based on colony colour and morphology with only a minimum of confirmatory tests.

HardyCHROM UTI can be used to differentiate between between E.coli and Enterococcus spp. with no further testing needed, based on their characteristic colour reactions.

• E. coli produces medium rose to magenta coloured colonies
• Enterococcus faecalis produces small, teal to turquoise coloured colonies
• Pseudomonas spp produce colourless to light yellow-green translucent colonies
• Klebsiella, Enterobacter and Serratia spp produce large deep blue to dark indigo colonies
• Proteus, Morganella and Providencia spp produce clear to light yellow colonies with a diffuse golden-orange halo in the medium
• S. saprophyticus produces opaque, pink coloured colonies
•  S. aureus produces opaque, cream to white coloured colour
