CHROMagar™ Salmonella Plus - 25 L

Description

Chromogenic medium for the isolation of Salmonella species including lactose positive Salmonella.

The product is composed of a powder base (B) , 1 supplement (S) and 1 optional supplement.

MEDIUM PERFORMANCE:
1. Meets ISO 6579-1 requirements by detecting lactose positive Salmonella. Detection of lactose positive Salmonella is required in food microbiology by the ISO 6579-1 standard.
2. Easy to read with the naked eye: Another feature of this new media resides in its nice colour contrast due to the fact that E. coli are colourless. E. coli, which are usually present in abundance in samples tested for Salmonella and can potentially hide suspect colonies, are no longer a concern.*
3. High Sensitivity and Specificity: Salmonella (including S. typhi, S. paratyphi A and lactose positive Salmonella) → 99 %*
*Specificity and sensitivity from scientific study: “Evaluation of a new chromogenic medium CHROMagar Salmonella Plus for the detection of Salmonella species including lactose positive Salmonella, S.Typhi and S.Paratyphi” de Beaumont C., Breuil J., Dedicova D., Tran Q. 2006. Poster presented during ECCMID meeting.

TYPICAL APPEARANCE OF MICROORGANISMS:
Salmonella (including S. typhi, S. paratyphi A and lactose positive Salmonella) → Mauve
E. coli → colourless
Coliforms, etc → blue
Proteus, etc → colourless or inhibited

Infections caused by Salmonella spp., including Salmonella typhi, remain a major worldwide health problem.
Mainly due to contamination in the food chain and/or during food-production processes, Salmonella commonly induces enteric illness whose major symptoms are abdominal cramps, diarrhea, nausea, and vomiting.

Also available in 5000 ml (SA162).
