Microbial Detection using Chromogenic Media

Rainbow® Agars offer a simple selective and chromogenic medium to help you conveniently detect strains of E. coli O157, Salmonella, Shigella and Aeromonas with results in less than 24 hours!

Created in accord with recommendations of microbial ecologists specifically for community analysis and microbial ecological studies. Biolog EcoPlates have been found to provide a sensitive and reliable index of environmental change.

Rainbow Agar Salmonella utilizes an enhanced detection chemistry to determine H2S production among Salmonella spp., Black colonies are formed by even weak H2S producing strains. In addition, novel selective agents increase the recovery rate of Salmonella while inhibiting the growth of other enteric bacteria and inhibiting H2S production by Citrobacterand other H2S positive enteric species.

Rainbow Agar Shigella/Aeromonas was developed to directly isolate these important causative agents of gastroenteritis. The medium is inhibitory to gram-postive bacteria and most non-enteric gram-negative bacteria, but is not toxic to the target species. Most other enteric species including Escherichia coli are significantly inhibited, and colonies that grow are blue. Strains of all four Shigella species (sonnei, flexneri, boydii and dysenteriae) as well as some Aeromonas species (hydrophila, jandaeiandtructi) grow as large or medium-sized orange-red colonies
