An Assessment of Rappaport-Vassiliadis Medium Based on Growth Kinetics

Abstract

The growth of eleven Salmonella serotypes cultured in modified Rappaport-Vassiliadis medium was compared with the growth in selenite broth and in nutrient broth. The growth of other enterobacteria in the three media was also studied. The mean generation times of all the serotypes were calculated by fitting the experimental data to the exponential growth law. The results showed that Rappaport-Vassiliadis medium sustained the growth of nine Salmonella serotypes and proved more successful in limiting the growth of other enterobacteria than did the selenite or nutrient broths.
