COMPASS® Salmonella Agar

Reference : BM23008

CAD$324.95

COMPASS® Salmonella Agar is a selective media allowing the isolation and differentiation of bacteria belonging to the genus Salmonella.
It can be used as the second media in all normalized and validated methods for the detection of Salmonella.

COMPASS® Salmonella Agar is also used in the context of the rapid alternative method for the detection of Salmonella (SESAME Salmonella TEST ®).

Available in ready-to-use medium:
20 or 120 Petri plates Ø 90 mm

In compliance with regulatory requirements, a USDA permit (VS 16-3) is mandatory for shipments from Canada to the USA due to the inclusion of peptone, an animal byproduct.

Available format:

20 plates
120 plates

Petri size

90mm

QUANTITY

COMPASS® Salmonella Agar combines two chromogenic substrates in order to detect two enzyme activities :

5-bromo-6-chloro-3-indolyl-caprylate (Magenta-caprylate) allows the revelation of the esteraise enzyme. Degraded by Salmonella, this enzyme leads to the formation of a red-violet (magenta) precipitate within the colony.
5-bromo-4-chloro-3-indolyl-β-D-glucopyranoside (X-glucoside) is also used for which the cleavage product is a blue precipitate.

Simultaneous detection of both activities allows for a coloration of Salmonella in distinct contrast to that of other bacteria. Studies have demonstrated the enhanced specificity for Salmonella detection using this method, including atypical serotypes which can cause confusion on other media. The detection of Salmonella Typhi and Paratyphi, lactose positive Salmonella (S. Seftenberg and sub-species arizonae and diarizonae), sucrose positive and non- motile serotypes (S. Pullorum and Gallinarum) is assured with this medium.

Selective agents inhibit Gram-positive and several Gram-negative species.
The nutrient base favors the recovery and growth of Salmonella.
