Rambach Agar

Rambach Agar is an innovative differential-diagnostic culture medium for the identification of Salmonella by colony staining with a specific marker

MacConkey, SS, XLD, and other agars unable to distinguish some Citrobacter and Proteus from Salmonella, Rambach Agar differentiates Salmonella colonies through the red colour they develop.
FAST: the specificity of Rambach Agar reduces the need for subculturing
and biochemical multi-testing
Incubation at 35-37°C.
Results after 18 h and 24 h.

Salmonella detection

PRINCIPLE
After the usual pre-enrichment and enrichment steps, the innovative selective medium Rambach Agar identifies Salmonella by simple colony staining with its specific marker:
? Salmonella colonies are coloured red (except for S. typhi i.e. clear to white colonies).
? commensal bacteria such as Proteus, E.Coli and Citrobacter develop colourless, blue or violet colonies.
INNOVATIVE ASPECTS
Rambach Agar combines:
? a new positive character (appearing red) for Salmonella: propylene glycol metabolism,
? another negative character (appearing blue): betagalactosidase.
