Rappaport Vassiliadis Medium is recommended for enrichment of Salmonellae, based on its ability to multiply selectively at high osmotic pressure, low pH and at 43deg C, with modest nutritional requirements. This media is designed according to the revised formulation by Van Schothorst et al and is recommended for the selective enrichment of Salmonellae from food and environmental specimens. It is a modification of the Rappaport Vassiliadis Enrichment Broth described by Van Schothorst and Renauld. The low pH of the medium, combined with the presence of malachite green and magnesium chloride, helps to select for the highly resistant Salmonella species.
Application: For Enrichment of Salmonellae, Based on its Ability to Multiply Selectively At High Osmotic Pressure, Low Ph and At 43°C, with Modest Nutritional Requirements
