Medium Performance
- Reliable: the first commercially available (1989) chromogenic medium, is still successful today, thanks to its performance.
- Very high sensitivity:
Salmonella → 93,9%*
*Sensitivlity from scientific study: Gruenewald, R. et al. 1991. Use of Rambach Propylene Glycol Containing Agar for Identification of Salmonella spp. J.C.M. 29: 2354-2356.
- Intense red colouration for easy reading, compared to other chromogenic media.
- Fast results: particularly useful in case of a sudden, dangerous outbreak of Salmonella food poisoning.
- High specificity / Lower worlkload: The conventional media for the detection of Salmonella by H2S character has very poor specificity, creating an abundance of false positives (Citrobacter, Proteus, etc.) among the rare real positive Salmonella. The workload for unnecessary examination of suspect colonies is so high that the real positive Salmonella colonies might often be missed in routine testing.
Because of their poor specificity, conventional media require tedious examination of at least 10 colonies per suspected sample.
On the contrary, Rambach Agar eliminates most of those false positives and allows technicians to focus on the real contaminated samples.
Medium Description
Gain flexibility using powder rather than ready to use plates:
Use the entire pack, or if there is a need for a smaller number of plates, just a portion. If kept under appropriate storage temperature, Rambach Agar has a 3 years shelf life. This flexibility is essential to avoid the waste resulting from expired-unused plates.

Focus on Salmonella
Despite its early discovery in the 1880’s, Salmonella remains a major worldwide pathogen and one of the most common food-borne poisons.
For instance, Salmonella has an incidence rate of 16.2 cases per 100,000 (CDC estimation, 2008).
Salmonella Epidemiologic Issues
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.
More severe cases, for instance typhoid cases or infections in immuno-depressed patients, can lead to body dehydration with renal failure or bacteraemia.
This underlines the importance of a continuous control of Salmonella along the entire food production chain.
Large scale testing is only possible with efficient detection tools.
