Evaluation of Enrichment Broth for the Bactometer (Conductance Method) on the Detection of Salmonella

Abstract

To apply the Bactometer for the rapid detection of Salmonella from foods, proper enrichment broths and incubation temperatures were examined in this study. The results obtained are shown as follows:
1. Detection of Salmonella was available within 10h by the conductance method with Impedance-Splitting Salmonell broth (ISS) 41°C incubation.
2. Growth of Citrobacter freundii, Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis were inhibited in ISS-41°C incubation.
3. By using Modified Lysine decarboxylase broth (MLD) 41°, C Salmonella was detected, but E. coli was not inhibited.
