Growth of Salmonella and competing flora in five commercial Rappaport-Vassiliadis (RV)-media.

Abstract Growth of 18 Salmonella strains belonging to 11 serotypes and the bacterial flora of deep-frozen broiler carcasses was examined in five commercial Rappaport-Vassiliadis (RV) media. Growth was measured by an automated turbidometer (Bioscreen R ). Significant differences in performance between the media investigated were observed. The unequal performances were ascribed to differences in the concentration of magnesium chloride (MgCl 2 ) and the type of peptone used.
