Modified Semi Solid Rappaport Vassiliadis Medium (MSRV) is a modification of Rappaport-Vassiliadis enrichment broth for detecting motile Salmonella spp. in faeces and food products. The original research on MSRV Medium revealed a semi-solid could be used as a rapid and sensitive test for isolating motile Salmonella spp. from food products following pre-enrichment or selective enrichment. The semi-solid medium allows motility to be detected as halos of growth around the original point of inoculation.
