[Method] Plasmids from 24 pathogenic Escherichia coli in musk deer were extracted by the Lysis Triton method, and then identified by single enzyme digestion with three endonucleases of Hind Ⅲ, EcoR Ⅰ and BamH Ⅰ. [Result] The yield rate of plasmids was 91.6%, and 24 pathogenic Escherichia coli in musk deer had the identical or similar plasmid profiles. [Conclusion] Plasmid DNA analysis offers scientific basis for molecular epidemiology of pathogenic Escherichia coli in musk deer in Sichuan Institute of Musk Deer Breeding.展开更多
