Selenite broth is used as a selective medium for the isolation of ''Salmonella'' species. Selenite Broth was originated by Leifson (), while observing good recovery of Salmonella spp. and reduced growth of fecal coliforms. Selenite Broth is used as a selective enrichment for the cultivation of Salmonella spp. that may be present in small numbers and competing with intestinal flora. This medium must not be autoclaved. Once prepared it is steamed at 100°C for 30 minutes. There should be a very slight red precipitate. To minimise the risk of teratogenicity to workers, sodium selenite must be added separately to the medium. It has a pH of approximately 7.1. Selenite broth contains: () Leifson, E. 1939.
