Human microbiome analysis is the study of microbial communities found in and on the human body. The goal of human microbiome profiling studies is to understand the role of microbes in health and disease. Next-generation sequencing (NGS) has fueled studies capable of surveying the genomes of entire microbial communities, including those of unculturable organisms.
Previously, studying human microbiome samples relied on time- and labor-intensive microbiology techniques of growing and isolating individual organisms followed by phenotypic or genotypic analysis. Microbial community profiling within a single sample was not possible with these older methods.
Microbial transcriptomics, or metatranscriptomics, provides key insights into the expressed RNAs encoded by a group of organisms in a complex sample. High-quality metatranscriptomics data enables researchers to quantify gene expression changes, predict resistance or susceptibility to specific treatments, understand host-pathogen immune interactions, and track disease progression.
The advent of next-generation sequencing enabled several high-profile collaborative projects such as the Human Microbiome Project, which has published a wide range of data on the human microbiome using NGS as a foundational tool.
NGS methods allow scientists to perform culture-free identification and classification of complex microbial communities. These methods can also accelerate discovery of novel species in microbiome samples and facilitate detection of virulence and antimicrobial resistance genes.
