Selenite Broth (Selenite-F Broth) is used as an enrichment medium for the isolation of Salmonella from feces, urine, water, foods and other materials of sanitary importance.
Enrichment media are routinely employed for detection of pathogens in fecal specimens since the pathogens usually represent only a small percentage of the intestinal flora. Selenite Broth and the related medium, Selenite Cystine Broth, are recommended for use in the recovery of Salmonella with subcultures being made after 12-18 hours of incubation. For detection of Shigella, GN Broth is a satisfactory enrichment medium. Campylobacter Thioglycollate Medium with 5 Antimicrobics is recommended for specimens suspected to contain Campylobacter jejuni.
