ERIC-PCR技术在李斯特氏菌种、菌株鉴定中的应用ERIC-PCR on Identification of Listeria Species and Strain
肠杆菌基因间重复一致序列 PCR 李斯特氏菌 DNA指纹图谱
2007/12/30
摘要应用肠杆菌基因间重复一致序列聚合酶链反应技术（ERIC-PCR）对李斯特氏菌基因组DNA进行分析，结果显示，李斯特氏菌种间DNA指纹图谱带型差异较大；单核细胞增生性李斯特氏菌株间及相同血清型不同来源的菌株，其DNA指纹图谱带型也有明显差异。在单核细胞增生性李斯特氏菌各株的DNA指纹图谱中发现1600bp的种专一性扩增带。结果表明，ERIC-PCR技术可用于李斯特氏菌种、菌株的鉴定及进一步分型研...
多种微生物搭载返回式卫星的试验研究 Experimental Studies of Species of Microorganisms on Board Retrievable Satellite
丝状真菌 禽巴氏杆菌 动物病毒 返回式卫星
2007/12/7
摘要利用我国发射的科学返回式卫星，对4种具有实际应用价值的真菌、1种细菌和3种动物病毒的生长及某些特性如产酶、毒力及免疫学等进行了初步研究。结果表明，从4株真菌所选育的变异株产酶活性都得到不同程度的提高，但生长速度有的加快，有的则变慢; 1种动物病毒和1种细菌的毒力降低，并能产生较好的免疫原性。
