Capable of detecting Salmonella species within 24 hours, Modified Semi-solid Rappaport Vassiliadis (MSRV) medium is one of a range of products from Lab M devoted to the detection and isolation of these organisms. MSRV medium offers a simple and rapid means of detecting motile strains of Salmonella, even if they are outnumbered by competitive bacteria by a factor of 107. MSRV medium is inoculated directly from pre-enrichment culture to the centre of the plate. Motile organisms spread through the semi-solid agar, with non-Salmonella being inhibited by selective agents in the medium. Spreading growth following overnight incubation indicates that Salmonella may be present. This is substantiated if a paper disc with polyvalent H antiserum has been included on the plate, and a zone of inhibition can be seen around it.
