依赖粪便材料的大熊猫肠道耶尔森氏菌的检测 总被引:2,自引:0,他引:2
It is inevitable to develop noninvasive sampling methods to do studies on giant panda even diagnose the diseases since which is so endangered that it's impossible to carry out invasive sampling. A non-invasive sampling method to detect the intestinal pathogen, Yersirda enterocolitica in feces of pandas based designing PCR primers was established in this study. The main procedures are based on bacteria enrichment and cell lysis before binding the pathogen DNA to silica powder at high concentration of Kalium iodide and neutral pH conditions. Before PCR cycles, the binded DNA is washed with 80% ethanol and eluted with diluted EDTA buffer. Restdts showed that the silica-based feces DNA-purification method could remove the inhibitors of PCR so applicable to detect the target pathogen. 相似文献
