| distribution and molecular characterization of salmonella enterica hypermutators in retail food in china. | hypermutable pathogens can easily acquire mutation opportunities, as well as antimicrobial resistance, and are tremendous hazards to food safety and public health. in this study, a total of 96 (7.6%) hypermutators were identified from 1,264 salmonella isolates recovered from retail foods. pulsed-field gel electrophoresis analysis indicated that hypermutators were genetically diverse. amino acid substitution of val421phe was detected in muts in one hypermutator and val246ala in 56 other hypermuta ... | 2015 | 26219361 |
