Rifampicin- Resistant Salmonella and Shiga-toxin-Producing Escherichia coli Exhibit Comparable Lactic Acid and Chlorine Stress Phenotypes to Wild-Type Strains.

Abstract excerpt

Using bacteria with rifampicin resistance can be useful when working with food matrices that have complex microbiota, though there is potential for repeated exposure to rifampicin during the selection process to introduce undesired mutations that lead to different phenotypic responses compared to the wild-type. In this study, we evaluated phenotypic responses of wild-type and rifampicin-resistant mutants for five...
