A study of the relative efficiencies of three commercially available dehydrated Rappaport–Vassiliadis media

Abstract: The relative efficiencies of three commercially available dehydrated Rappaport-Vassiliadis media have been compared with a similar medium prepared from individual constituents in our own laboratory. An inoculation ratio of 1:100 was found to be optimal for each of the media tested. Laboratory produced RV-medium was significantly better than the three commercial preparations after 24 h incubation. However, when the duration of incubation was extended to 48 h, there was no significant difference in the number of… Show more

“…Interestingly, greater method sensitivity was obtained with postenrichments derived from RV inocu-43 lated with a transfer volume of 0.1 m!. These results are consistent with earlierreports on the intrinsically low selectivity of the RV 43 medium, and need for its inoculation at a I: 100 preenrichment to enrichment ratio for optimal recovery (11, 22,25,31).…”

“…(15) ilk olarak 1976'da Rappaport'un Salmonella'lar için MgCl 2-malaşit yeşili zenginleştirme besiyerine iki önemli modifikasyon getirdiklerinden beri diğer birçok araştırmacı besiyerinin dinamik ve kinetiğini araştırmış ve ek modifikasyonlar içeren besiyerlerinin verimliliğini karşılaştırmıştır. Bu ve buna benzer çalışmalar RV besiyerinin Salmonella'lar için (Salmonella serotip Typhi hariç) geleneksel zenginleştirme besiyerleri olan tetratiyonat ve selenit besiyerlerinden üstünlüğünü göstermiştir (15)(16)(17)(18)(19) .
