Use RAPID'Salmonella Supplement Box for sample enrichment prior to the detection and enumeration of all Salmonella spp. in products intended for human or animal consumption, or in environmental samples. After enrichment, identification using RAPID'Salmonella Medium is based on the chromogenic detection of C8-esterase activity, while simultaneous detection of β-glucosidase activity permits the differentiation of Salmonellafrom other Enterobacteriaceae.
Features and Benefits
- Supplement enables highly effective Salmonella growth, even when stressed, while limiting the growth of interfering flora
- After enrichment Salmonella spp. form magenta colonies on RAPID'Salmonella Agar, while non-Salmonellaspp. form blue or uncolored colonies
- Detection of motile and non-motile Salmonella, lactose-positive Salmonella, and Salmonella Typhi/Paratyphi
- Results in <42 hr
Options for confirmation of Salmonella and serotype identification include the latex agglutination test (Salmonellagroups B to E and G), iQ-Check® Salmonella II Real-Time PCR Test, evaluation of cytochrome c oxidases, ONPG Test (β-galactosidase), and Bio-Rad’s extensive range of antisera to flagellar, somatic, and capsular antigens.
Validations
- Certified NF VALIDATION according to the ISO 16140 standard and validated by the AOAC
- RAPID'Salmonella Medium can be used as a second medium in the ISO 6579 standard
