An assessment of US microbiome research.

Genome-enabled technologies have supported a dramatic increase in our ability to study microbial communities in environments and hosts. Taking stock of previously funded microbiome research can help to identify common themes, under-represented areas and research priorities to consider moving forward. To assess the status of US microbiome research, a team of government scientists conducted an analysis of federally funded microbiome research. Microbiomes were defined as host-, ecosystem- or habitat-associated communities of microorganisms, and microbiome research was defined as those studies that emphasize community-level analyses using ‘omics technologies.
