Use Rappaport-Vassiliadis Soya Peptone Broth for selective enrichment of Salmonella spp. from food and environmental specimens.
• Selective: malachite green, low pH, and high magnesium chloride concentration inhibit many Gram-positive bacteria, while selectively enriching for salmonellae.
• Superior performance to Selenite Enrichment Broth and Tetrathionate Broth for the enrichment of salmonellae with the exception ofSalmonella typhi^1RVS Broth is based on the revised formulation described by van Schothorst et al.^3, and is recommended as the selective enrichment medium for the isolation of salmonellae from food and environmental specimens. It can also be used to isolate salmonellae from human feces without the need for pre-enrichment. It is a modification of the Rappaport Vassiliadis (RV) Enrichment Broth described earlier by van Schothorst and Renauld^4. The modifications to their earlier formula are:
• The addition of dipotassium hydrogen phosphate to buffer the medium so that the pH is maintained during storage of the prepared broth.
• Clarifying the optimum concentration of magnesium chloride 6H_2O.The two modifications are said to enhance the reliability of the enrichment broth^1. Peterz et al.^3 have also highlighted the importance of the concentration of magnesium chloride in the final medium.RVS Peptone Broth is based on the revised formulation and is recommended as the selective enrichment medium for the isolation of salmonellae from food and environmental specimens. It can also be used to isolate salmonellae from human feces without the need for pre-enrichment.Not all products are available for sale in all territories.
