| Abstract: |
| objective:construct pulsed-field gel electrophoresis maps of malgenic Escherichia coli.Method:segregated bacterial DNA used pulsed-field gel electrophoresis technology.Then marked with EB.Analyzed maps with Info Quest FP cluster analysis software in the end.Consequence:pulsed-field gel electrophoresis maps of 127 malgenic Escherichia coli strains included by CVCC Catalogue of Cultures were obtained,in which 12 strains including CVCC212 and CVCC213 were correlated to epidemiology of Escherichia coli.Conclusion:pulsed-field gel electrophoresis maps of 127 malgenic Escherichia coli strains constructed in the experiment consummated background information of malgenic Escherichia coli The experiment provided valuable data for analyzing further relationship between genotyping and pathogenicity. |
