Phenolphthalein, an acid–base indicator, was added to detect the formation or presence of hydroxide ions. Growthcould easily be interpreted. Obtain a tube of semi-solid agar (motility butt, 0.4% agar). Semi-solid agar: Contains less agar than solid media (0.5% agar). Furthermore, ourisolation rate ofSalmonella species fromfecal samples showed an increase of 22.3% whenthis semisolid mediumwasadded to the routine culture media. The semi-solid medium used in the study was'composedof 0.3 per cent meat extract, 0.5 per cent peptone and0.5 per cent agar. Semisolid Nutrient Agar is recommended for detection of Salmonellae on the basis of motility and hydrogen sulphide (H2S) production(2,3). Modified Semi-Solid Rappaport-Vassiliadis (MSRV) Agar is used with Novobiocin for the rapid detection of motile Salmonella spp. At 20-28°C, Listeriae inoculated into the agar column swarm through the ‘motility medium’ and produce cloudiness.
