Nitrate contamination in ground and surface water is an increasingly serious environmental problem and only a few bacterial strains have been identified that have the ability to remove nitrogen pollut...
Influenza has been circulating in the human population and has caused three pandemics in the last century (1918 H1N1, 1957 H2N2, 1968 H3N2). The 2009 A(H1N1) was classified by the World Health Organiz...
Pregnant women have increased susceptibility to malaria infection. In these women, malaria parasites are frequently found sequestered in the placental intervillous spaces, a condition referred to as p...
Approximately 24 million pregnant women in Sub-Saharan Africa are at risk of suffering from pregnancy malaria complications. Mechanisms responsible for increased susceptibility to malaria in pregnant ...
Parthenogenetic embryonic stem (pES) cells could provide a valuable model for research into genomic imprinting and X-linked diseases. In this study, pES cell lines were established from oocytes of hyb...

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...
摘要常规方法分离鉴定47株大肠埃希菌,以标准纸片扩散法(KB法)对其进行常用氨基糖苷类药物敏感性测定,耐药株经PCR检测aac(3)Ⅱ基因保守区,扩增产物进行DNA测序分析。初步探讨大肠埃希菌氨基糖苷类抗生素耐药株与aac(3)Ⅱ基因保守区之间的关系,结果显示本地区大肠埃希菌氨基糖苷类抗生素耐药株的aac(3)Ⅱ基因保守区具65位G、84位T和65位A、84位C两种基因型,且高...
