Gut Microbiota and its importance Linking short gene fragments to organisms. The Human Microbiome is the collection of all the microorganisms living in association with the human body. The core microbiome is whatever factors are common to the microbiomes of all or the vast majority of humans. 2018 Chronic stress promotes colitis by disturbing the gut microbiota and triggering immune system response. The microorganisms that live inside and on humans (known as the microbiota) are estimated to outnumber human somatic and germ cells by a factor of ten.

Moreover, when adult germ-free wild-type mice were colonized with a gut microbiota from obese (ob/ob) or lean (+/+) mice, adiposity increased to a significantly greater degree in recipients of the microbiota from obese mice than in recipients of the microbiota from lean mice, supporting the conclusion that the obesity-associated gut microbiota has an increased (and transmissible) capacity to promote fat deposition19. These microbes are generally not harmful to us, in fact they are essential for maintaining health.

It is hoped that the HMP will not only identify new ways to determine health and predisposition to diseases but also define the parameters needed to design, implement and monitor strategies for intentionally manipulating the human microbiota, to optimize its performance in the context of an individual's physiology. Thus, another key challenge for the HMP is to define the concept of 'distance' between communities and to associate these distances with host biology and various metadata. 32, D277D280 (2004).

Research has yielded tremendous insight into the links between the microbiome, environmental exposures, and human health. Many outcomes of the HMP can be predicted: for example, new diagnostic biomarkers of health, a twenty-first century pharmacopoeia that includes members of the human microbiota and the chemical messengers they produce, and industrial applications based on enzymes that are produced by the human microbiota and can process particular substrates. Microbiome learning tools for students First tier: initial data acquisition and analysis, Pillar one: construct deep draft assemblies of reference genomes, Select cultured representatives of microbial divisions in a given habitat by examining 'comprehensive' 16S-rRNA-gene-based surveys, Create a publicly accessible database of human-associated 16S rRNA gene phylotypes (which could be referred to as the 'virtual microbial body') to facilitate selection by allowing comparisons within and between body habitats, within and between individuals, and between separate studies; and develop faster and better alignment algorithms for building phylogenetic trees, Obtain phylotypes of interest from existing culture collections (both public and 'private'), with consent to deposit sequence data in the public domain, Improve technology for culturing organisms that cannot be cultured at present, Select a subset of 'species' for pan-genomic analysis (that is, the characterization of multiple isolates of a species-level phylotype), and develop better methods for detecting horizontal gene transfer, Ensure data flow to, and data capture by, the Protein Structure Initiative (http://www.structuralgenomics.org), Deposit sequenced isolates, together with information about habitat of origin, conditions for growth and phenotypes, in a public culture repository that can maintain and distribute microorganisms, Pillar two: obtain reference microbiome data sets, Focus on monozygotic and dizygotic twin pairs and their mothers, Determine the advantages and disadvantages of different DNA-sequencing platforms, Characterize, at a preliminary level, within-sample () diversity and between-sample () diversity, Ensure the availability of user-friendly public databases in which biomedical and environmental metagenomic data sets are deposited, together with sample metadata, Develop and optimize tools (distance metrics) for comparing 16S rRNA gene and community metagenomic data sets, and feed back to the pipeline in which cultured or retrieved representatives of different habitat-associated communities are selected and characterized, Establish specimen and data archives with distribution capabilities, Generate large-insert microbiome libraries for present and future functional metagenomic screens, Coordinate with environmental metagenomics initiatives so that efforts to develop resources and tools are reinforced and shared, Pillar three: obtain shallower 16S rRNA gene and community metagenomic data sets from moderate number of samples, Extend sampling of families (for example, to fathers, siblings and children of twins), expand the age range of individuals sampled, and explore demographic, socio-economic and cultural variables, Establish a global sample-collection network, including countries in which social structures, technologies and lifestyles are undergoing rapid transformation, Develop and optimize computational tools and metrics for comparing these diverse multivariate data sets, Develop and optimize tools for analysing the transcriptome, proteome and metabolome, by using the same biological specimens used for sequencing community DNA, and develop and optimize tools for higher-throughput analyses, Design and test experimental models for identifying the principles that control the assembly and robustness of microbial communities, Second tier: choice of individuals that represent different clusters, for additional deep sequencing, Estimate sampling depth and number of individuals needed to characterize the 'full' human microbiome; the granularity of the characterization needs to match the data, Search for relatives of human-associated microbial species and gene lineages in other mammalian microbial communities and in the environment, and sequence the genomes of these microorganisms (defining niches; feed back to the first tier), Third tier: global human microbiome diversity project, Sequence at a shallow level the microbiomes from a large (to be defined) sample of geographically, demographically and culturally diverse individuals, Choose individuals with different clinical 'parameters', and carry out association studies and biomarker panning, Sequence at a large scale reservoirs of microorganisms and genes (for example, soils and water sources), and associate this information with the fluxes of energy, materials, genes and microbial lineages into the human microbiome (with the help of microbial observatories and human observatories), Apply the knowledge gained (for example, towards developing diagnostic tests, therapies and strategies for improving the global food chain), and educate people (including the public, governments, and present and future researchers in the field).
