Salmonella including S. typhi,
S. paratyphi A and lactose positive Salmonella
mauve
Coliforms
blue
E. coli
colourless
Performance
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, vomiting.
1. Meets ISO 6579-1 requirements by detecting lactose positive Salmonella in intense mauve color.
2. Easy to read by naked eye: Another feature of this medium resides in its nice colour contrast due to the fact that E. coli are colourless. E. coli, which ate usually present in abundance in samples tested for Salmonella and could potentially hide suspect colonies, are no longer a concern.
3. High Sensitivity and Specificity:
Salmonella including lactose positive Salmonella : 99 %*
*Specificity and sensibility 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.
