RAPID’Salmonella™ medium is a sensitive chromogenic agar used for the detection and enumeration of Salmonella spp. in products that are intended for human and animal consumption.
Sensitive and Easy to Read
The high specificity and high selectivity of RAPID’Salmonella medium are due to the combination of enzymatic activities and the inhibition of contaminating food flora. The principle of the RAPID’Salmonella medium relies on the demonstration of two enzymatic activities. Salmonella spp. take the form of readily identified typical magenta colonies (due to the detection of C8 esterase) in 24 hr. Counter selection (β-D glucosidase) is used in RAPID’Salmonella medium to reveal other bacteria with a different color. RAPID’Salmonella medium can detect motile and non-motile Salmonella, as well as lactose-positive Salmonella, including S. typhi and S. paratyphi.
Rapid and Economical Method
The RAPID’Salmonella medium can be used with a shortened protocol to obtain full results within 42 hr using one plate and one broth. An alternative confirmation is also validated in the RAPID’Salmonella protocol, which gives results in 1 hr directly from isolated colonies.
RAPID’Salmonella chromogenic plating agar can also be used
- As a second selective medium in different standardized protocols (for example, ISO 6579 reference method)
- To confirm positive tests on the iQ-Check® Salmonella II kit
