[Rappaport--Vassiliadis medium--a new liquid selectively-multiplying medium for detection of Salmonella in food]

On the basis of the available literature, the history of development of the Rappaport--Vassiliadis (RV) medium, its preparation and applicability in food control methods were described. Results of comparative studies on the effectiveness of Salmonella isolation upon use of different specifically-multiplying media: MK, medium containing sodium acid selenite, R25/37 degrees C, RV, were presented. The number of Salmonella isolations in samples multiplied in RV medium was found to exceed that obtained upon use of the remaining media. Moreover, RV medium was easy to prepare; it proved to be economical and was stable for up to 7 months when refrigerated.
