A total of 745 samples of chicken giblets was cultured to determine the relative efficiency of a commercially available Rappaport-Vassiliadis medium (RV-Oxoid). Experiments to determine the optimum inoculation ratio showed that 1:100 was superior to the other ratios tested. Comparison of RV-Oxoid with standard RV and RV-medium prepared using soya peptone (RV-soya) showed that after 24 h RV-soya was significantly better than RV-Oxoid (P < 0·05), although there was no significant difference between standard RV and RV-Oxoid. Furthermore, when the duration of incubation was extended to 48 h there was no significant difference between the three media (P > 0·25).

We conclude that RV-Oxoid is a satisfactory product for the isolation of salmoncllae from poultry, providing that it is inoculated at a ratio of 1:100 and is incubated for 48h. Its use can therefore be recommended to laboratories who wish to use a dehydrated medium.
