(Characterizing human fecal microbial communities Methods for V4-16S rRNA gene sequencing and data analysis, calculation of MAZ scores and functional microbiome maturity, and quantification of enteropathogen burden by means of multiplex quantitative polymerase chain reaction (qPCR) are described in the sup...
16s rRNAintestinal inflammationUser-friendly computational tools for 16S ribosomal RNA (rRNA) sequencing analysis enable researchers who are not bioinformaticians to analyze and interpret sequencing data from microbial communities. These tools' easy-to-use interfaces belie the sophisticated and rapidly-...
近期,南京农业大学食品科学技术学院周光宏教授和李春保教授团队在国际期刊《Food Research International》(农林科学1区top)在线发表了题为“Assessment of quality characteristics and bacterial community of modified atmosphere packaged chilled pork loins using 16S rRNA amplicon sequencing analysis”的研究论文。周光宏...
图摘要:糖尿病小猪的肠道微生物结构发生了改变 中国人民解放军总医院实验动物中心的陈华等研究人员,应用高脂饮食联合低剂量链脲佐菌素的方法建立了糖尿病小型猪模型,采用16S核糖体RNA(rRNA)基因测序,评估糖尿病小型猪肠道微生物群的特征。结果表明,糖...
稀释曲线是利用已测得16S rRNA序列中已知的各种OTU的相对比例,来计算抽取n个(n小于测得reads序列总数)reads时出现OTU数量的期望值,然后根据一组n值(一般为一组小于总序列数的等差数列)与其相对应的OTU数量的期望值(此处采用chao1算法估计),当曲线趋向平坦时,说明测序数据量合理,更多的数据量只会产生少量新的OTU,...

宏基因组测序(Metagenomics Sequencing)是对环境样品中全部微生物的总DNA进行高通量测序,主要研究微生物种群结构、基因功能、微生物之间的相互协作关系以及微生物与环境之间的关系。宏基因组测序研究摆脱了微生物分离纯培养的限制,扩展了微生物资源的利用空间,为环境微生物群落的研究提供了有效工具。 高通量测序平台 16S扩...
16S rRNA编码基因序列共有9个保守区和9个高可变区。其中,V4区其特异性好,数据库信息全,我们通过大量的测序试验证明用v4区扩增出菌群结果的可以很好的反应样本的菌群结构用于后续的数据建模分析,是细菌多样性分析注释的最佳选择。 基本确定好后,就要着手开始实验,实验完送样又是个问题,以往给测序公司送样往往是低温...
The 16S rRNA gene has been a mainstay of sequence-based bacterial analysis for decades. However, high-throughput sequencing of the full gene has only recently become a realistic prospect. Here, we use in silico and sequence-based experiments to criticall
