A note on the use of Rappaport-Vassiliadis medium (R10/RV) for the isolation of salmonellas from sewage and sewage sludges

The use of a modified Rappaport broth for the selective enrichment of salmonellas in sewage sludge is described. Comparative trials were carried out using Muller Kauffman--Tetrathionate (MKT) broth and Rappaport-Vassiliadis (R10/RV) medium for selective enrichment. Results have indicated that R10/RV broth is more selective and is to be preferred for routine monitoring.
