Rambach Agar The conventional media for the detection of Salmonella by H2S character has a very poor specificity creating an abondance of false positives (Citrobacter, Proteus, etc. as suspect colonies) among the rare real positive Salmonella. The workload for unnecessary examination of suspect colonies is so high that the real positive Salmonella colonies might often be missed in a routine testing. In order to distinguish the real positive, the conventional method requires the tedious examination of 10 colonies per suspected sample. On the other hand Rambach Agar will eliminate most false positives and allow the technicians to focus all attention on rare suspected samples. These samples could be further identified as real positive for Salmonella. Because Rambach Agar has a very high specificity: (1) fewer samples are positive and have to be checked and (2) there is no further need to investigate 10 different colonies per sample. Overall workload will be reduced and in a routine examination one can detect with higher frequency the samples containing Salmonella. This is particularly useful in case of sudden, dangerous outbreak of Salmonella food poisoning.
