Descrição

Descrição geral

NutriSelect^® Bismuth Sulfite (BS) Agar introduced by Wilson-Blair (1927) is specifically designed for the isolation and differentiation of Salmonella spp from food, animal feed and other materials precisely when the detection of Salmonella enterica subspecies enterica serovars Typhi and Paratyphi is of concern.
Colonies of H₂S positive Salmonella exhibit blackening due to the formation of iron sulfide. The media selectivity is enhanced by the presence of brilliant green and bismuth sulfite which inhibit the growth of gram-positive bacteria and coliforms in the sample.
Peptone, meat extract and glucose allow good growth. Disodium phosphate acts as a buffer to maintain pH and agar is the solidifying agent.

Aplicação

NutriSelect^® Bismuth Sulfite (BS) Agar is used to isolate and differentiate Salmonella spp. from food animal feed and other materials. The medium is used to selectively grow the species when S. typhi and S. paratyphi are expected.

Nota de análise

Salmonella colonies display blackening after 18 hrs of incubation.

Nota de rodapé

We offer two media types: the superior granulated GranuCult^® and the cost-efficient powdered NutriSelect^® culture media, depending on your needs.
The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.
