Traditional methods for the isolation of Vibrio spp. (e.g. TCBS medium) are labour intensive and not particularly sensitive. Colorex™ Vibrio allows for the easy differentiation of V.parahaemolyticus from V.cholerae and V.vulnificus and other Vibrio spp. at the initial isolation stage while retaining a higher level of sensitivity than conventional methods. V.parahaemolyticus produces colonies with a mauve colouration while V.cholerae and V.vulnificus produce colonies with a blue colouration. Colorex™ Vibrio is a highly selective medium with most major Enterobacteriaceae spp. and Gram positive organisms being inhibited during incubation.
