Descripción

General description

GranuCult^® prime Selenite Cystine Broth is for the selective enrichment of Salmonella from food and animal feed and other materials, especially when the detection of Salmonella enterica subspecies enterica serovars Typhi and Paratyphi is of specific concern.
Peptones including the enzymatic digest of casein provide nitrogen, vitamins, amino acids and Lactose provides the carbon sources. Disodium phosphate acts as a buffer to maintain the pH.
Selenite inhibits the growth of coliform bacteria and enterococci in the first 6-12 hours of incubation, its inhibitory effect then gradually declines.
L-Cystine is considered to enhance the growth of Salmonella by reduction of toxicity. According to the modification described by North and Bartram (1953), L-Cystine is added to the original formulation of Leifson (1936).

Application

GranuCult^® prime Selenite Cystine Broth is used for the selective enrichment of Salmonella from food and animal feed and other materials, especially when the detection of Salmonella enterica subspecies enterica serovars Typhi and Paratyphi is of specific concern.
