Analysis of human microbiome using NGS.

: Recently, next generation sequencers(NGS)became prevalent and enable us possible to comprehensively analyze the entire human microbiome community structures including difficult-to-culture microbes. In this review, we introduce the NGS-based analytical methods of human microbiome, called "meta-16S analysis" and "metagenomic analysis", then show several fundamental data basing these analyses. Furthermore, we also introduce the importance of database improvement used for analysis and the DNA preparation method from human samples.
