CHROMagar™ Salmonella - 5000 ml

Description

Chromogenic medium for detecton and isolaton of Salmonella species, including S. typhi and S. paratyphi in clinical specimens.

The product is composed of one single powder medium.

MEDIUM PERFORMANCE:
1. Easy reading: intense mauve colony colours for better identification.
2.Greater Specificity / Less workload: conventional media for the detection of Salmonella by H2S character have very poor specificity resulting in numerous false positives (Citrobacter, Proteus, etc.) among the rare, real positive Salmonella. The workload for unnecessary examination of suspect colonies is so heavy that real positive Salmonella colonies might often be overlooked in routine testing. Because of their poor specificity, conventional media require a tedious examination of at least 10 colonies per suspected sample. On the contrary, CHROMagar™ Salmonella eliminates most of those false positives and allows technicians to focus on the real contaminated samples.
3. High sensitivity, leading to a higher detection rate of Salmonella: Salmonella sensitivity: 95%*, Specificity: 88,9%* compared to 78% with Hektoen Agar.
*Specificity and sensitivity from scientific study: “Comparison of CHROMagar Salmonella medium and Hektoen Enteric Agar for isolation of Salmonellae from stool samples.” Gaillot O. et al. 1999. Journal of Clinical Microbiology, 37 : 762-765.
4. Dramatic decrease of the workload:
Number of useless confirmatory tests is minimized since there is no need of duplicating them.

TYPICAL APPEARANCE OF MICROORGANISMS:
Salmonella → mauve
Other bacteria → blue, colourless, or inhibited.

Infectons 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, vomiting.
More severe cases, for instance typhoid cases or infections in immuno-depressed patients, can lead to body dehydration with renal failure or bacteraemia.

Also available in 25 L (SA133-25).
