Recent developments in culture media have given rise to the use of chromogenic substrates as a means of differentiating bacteria particularly among the coliform group of organisms. Colorex™ UTI has been developed primarily for use in the examination of urine specimens with the aim of simplifying the differentiation and presumptive identification of the main organisms, gram negative and gram positive, usually found in urinary tract infections. It can however be used to differentiate organisms in other types of clinical specimens. The distinctive colonial colouration of the various species can reduce the need for additional follow up testing allowing many positive results to be issued within 24 hours of receipt of the sample. If necessary an Indole test for confirmation of Escherichia coli and TDA test for Proteus spp. can be performed directly from the medium.
