BM0370 – Mannitol Selenite Broth

Selenite Mannitol Broth is an alternative to Selenite F Broth for the selective enrichment of Salmonellae spp from Clinical, Food and Environmental specimens. Based on Buffered Mannitol Broth, it is made selective by the addition of Sodium Biselenite. The fermentation of Mannitol by Salmonellae is said to correct the alkaline pH swing which can occur during incubation. Following overnight incubation subculture(s) are usually made on to one or more of the many selective enteric solid media.
