CHROMagar Rambach Agar 5000ml

For the detection and isolation of Salmonella spp. in clinical and food samples.
 

Performance

Despite its early discovery in the 1880’s, Salmonella remains a major worldwide pathogen and one of the most common causes of food-borne infections. For instance, in the US, Salmonella has an incidence rate of 16.2 cases per 100,000 (CDC estimation, 2008).

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.

1.  Reliable : The first commercially available (1989) chromogenic medium for Salmonella is still successful today, thanks to its performance. It can be also used with clinical specimens.

2. High specificity / less workload : 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 a 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.

3. Very high sensitivity  : Salmonella → 93,9 %*

*Sensitivity 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.

4. Intense red colouration : for easy reading, compared to other chromogenic media.

5. Fast results : particularly useful in case of a sudden, dangerous outbreak of Salmonella food poisoning.
