Description: Our knowledge of species and functional composition of the human gut microbiome is rapidly increasing, but it is still based on very few cohorts and little is known about variation across the world. By combining 22 newly sequenced faecal metagenomes of individuals from four countries with previously published data sets, here we identify three robust clusters (referred to as enterotypes hereafter) that are not nation or continent specific. We also confirmed the enterotypes in two published, larger cohorts, indicating that intestinal microbiota variation is generally stratified, not continuous. This indicates further the existence of a limited number of well-balanced host-microbial symbiotic states that might respond differently to diet and drug intake. The enterotypes are mostly driven by species composition, but abundant molecular functions are not necessarily provided by abundant species, highlighting the importance of a functional analysis to understand microbial communities. Although individual host properties such as body mass index, age, or gender cannot explain the observed enterotypes, data-driven marker genes or functional modules can be identified for each of these host properties. For example, twelve genes significantly correlate with age and three functional modules with the body mass index, hinting at a diagnostic potential of microbial markers.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3728647/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3728647/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arumugam, Manimozhiyan -- Raes, Jeroen -- Pelletier, Eric -- Le Paslier, Denis -- Yamada, Takuji -- Mende, Daniel R -- Fernandes, Gabriel R -- Tap, Julien -- Bruls, Thomas -- Batto, Jean-Michel -- Bertalan, Marcelo -- Borruel, Natalia -- Casellas, Francesc -- Fernandez, Leyden -- Gautier, Laurent -- Hansen, Torben -- Hattori, Masahira -- Hayashi, Tetsuya -- Kleerebezem, Michiel -- Kurokawa, Ken -- Leclerc, Marion -- Levenez, Florence -- Manichanh, Chaysavanh -- Nielsen, H Bjorn -- Nielsen, Trine -- Pons, Nicolas -- Poulain, Julie -- Qin, Junjie -- Sicheritz-Ponten, Thomas -- Tims, Sebastian -- Torrents, David -- Ugarte, Edgardo -- Zoetendal, Erwin G -- Wang, Jun -- Guarner, Francisco -- Pedersen, Oluf -- de Vos, Willem M -- Brunak, Soren -- Dore, Joel -- MetaHIT Consortium -- Antolin, Maria -- Artiguenave, Francois -- Blottiere, Herve M -- Almeida, Mathieu -- Brechot, Christian -- Cara, Carlos -- Chervaux, Christian -- Cultrone, Antonella -- Delorme, Christine -- Denariaz, Gerard -- Dervyn, Rozenn -- Foerstner, Konrad U -- Friss, Carsten -- van de Guchte, Maarten -- Guedon, Eric -- Haimet, Florence -- Huber, Wolfgang -- van Hylckama-Vlieg, Johan -- Jamet, Alexandre -- Juste, Catherine -- Kaci, Ghalia -- Knol, Jan -- Lakhdari, Omar -- Layec, Severine -- Le Roux, Karine -- Maguin, Emmanuelle -- Merieux, Alexandre -- Melo Minardi, Raquel -- M'rini, Christine -- Muller, Jean -- Oozeer, Raish -- Parkhill, Julian -- Renault, Pierre -- Rescigno, Maria -- Sanchez, Nicolas -- Sunagawa, Shinichi -- Torrejon, Antonio -- Turner, Keith -- Vandemeulebrouck, Gaetana -- Varela, Encarna -- Winogradsky, Yohanan -- Zeller, Georg -- Weissenbach, Jean -- Ehrlich, S Dusko -- Bork, Peer -- 076964/Wellcome Trust/United Kingdom -- 082372/Wellcome Trust/United Kingdom -- England -- Nature. 2011 May 12;473(7346):174-80. doi: 10.1038/nature09944.

Description: Whereas large-scale efforts have rapidly advanced the understanding and practical impact of human genomic variation, the practical impact of variation is largely unexplored in the human microbiome. We therefore developed a framework for metagenomic variation analysis and applied it to 252 faecal metagenomes of 207 individuals from Europe and North America. Using 7.4 billion reads aligned to 101 reference species, we detected 10.3 million single nucleotide polymorphisms (SNPs), 107,991 short insertions/deletions, and 1,051 structural variants. The average ratio of non-synonymous to synonymous polymorphism rates of 0.11 was more variable between gut microbial species than across human hosts. Subjects sampled at varying time intervals exhibited individuality and temporal stability of SNP variation patterns, despite considerable composition changes of their gut microbiota. This indicates that individual-specific strains are not easily replaced and that an individual might have a unique metagenomic genotype, which may be exploitable for personalized diet or drug intake.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3536929/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3536929/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schloissnig, Siegfried -- Arumugam, Manimozhiyan -- Sunagawa, Shinichi -- Mitreva, Makedonka -- Tap, Julien -- Zhu, Ana -- Waller, Alison -- Mende, Daniel R -- Kultima, Jens Roat -- Martin, John -- Kota, Karthik -- Sunyaev, Shamil R -- Weinstock, George M -- Bork, Peer -- U54 HG003079/HG/NHGRI NIH HHS/ -- U54 HG004968/HG/NHGRI NIH HHS/ -- U54HG003079/HG/NHGRI NIH HHS/ -- U54HG004968/HG/NHGRI NIH HHS/ -- England -- Nature. 2013 Jan 3;493(7430):45-50. doi: 10.1038/nature11711.

Description: To understand the impact of gut microbes on human health and well-being it is crucial to assess their genetic potential. Here we describe the Illumina-based metagenomic sequencing, assembly and characterization of 3.3 million non-redundant microbial genes, derived from 576.7 gigabases of sequence, from faecal samples of 124 European individuals. The gene set, approximately 150 times larger than the human gene complement, contains an overwhelming majority of the prevalent (more frequent) microbial genes of the cohort and probably includes a large proportion of the prevalent human intestinal microbial genes. The genes are largely shared among individuals of the cohort. Over 99% of the genes are bacterial, indicating that the entire cohort harbours between 1,000 and 1,150 prevalent bacterial species and each individual at least 160 such species, which are also largely shared. We define and describe the minimal gut metagenome and the minimal gut bacterial genome in terms of functions present in all individuals and most bacteria, respectively.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3779803/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3779803/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Qin, Junjie -- Li, Ruiqiang -- Raes, Jeroen -- Arumugam, Manimozhiyan -- Burgdorf, Kristoffer Solvsten -- Manichanh, Chaysavanh -- Nielsen, Trine -- Pons, Nicolas -- Levenez, Florence -- Yamada, Takuji -- Mende, Daniel R -- Li, Junhua -- Xu, Junming -- Li, Shaochuan -- Li, Dongfang -- Cao, Jianjun -- Wang, Bo -- Liang, Huiqing -- Zheng, Huisong -- Xie, Yinlong -- Tap, Julien -- Lepage, Patricia -- Bertalan, Marcelo -- Batto, Jean-Michel -- Hansen, Torben -- Le Paslier, Denis -- Linneberg, Allan -- Nielsen, H Bjorn -- Pelletier, Eric -- Renault, Pierre -- Sicheritz-Ponten, Thomas -- Turner, Keith -- Zhu, Hongmei -- Yu, Chang -- Li, Shengting -- Jian, Min -- Zhou, Yan -- Li, Yingrui -- Zhang, Xiuqing -- Li, Songgang -- Qin, Nan -- Yang, Huanming -- Wang, Jian -- Brunak, Soren -- Dore, Joel -- Guarner, Francisco -- Kristiansen, Karsten -- Pedersen, Oluf -- Parkhill, Julian -- Weissenbach, Jean -- MetaHIT Consortium -- Bork, Peer -- Ehrlich, S Dusko -- Wang, Jun -- 085775/Wellcome Trust/United Kingdom -- England -- Nature. 2010 Mar 4;464(7285):59-65. doi: 10.1038/nature08821.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉BGI-Shenzhen, Shenzhen 518083, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20203603" target="_blank"〉PubMed〈/a〉

Description: Microbes are dominant drivers of biogeochemical processes, yet drawing a global picture of functional diversity, microbial community structure, and their ecological determinants remains a grand challenge. We analyzed 7.2 terabases of metagenomic data from 243 Tara Oceans samples from 68 locations in epipelagic and mesopelagic waters across the globe to generate an ocean microbial reference gene catalog with 〉40 million nonredundant, mostly novel sequences from viruses, prokaryotes, and picoeukaryotes. Using 139 prokaryote-enriched samples, containing 〉35,000 species, we show vertical stratification with epipelagic community composition mostly driven by temperature rather than other environmental factors or geography. We identify ocean microbial core functionality and reveal that 〉73% of its abundance is shared with the human gut microbiome despite the physicochemical differences between these two ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sunagawa, Shinichi -- Coelho, Luis Pedro -- Chaffron, Samuel -- Kultima, Jens Roat -- Labadie, Karine -- Salazar, Guillem -- Djahanschiri, Bardya -- Zeller, Georg -- Mende, Daniel R -- Alberti, Adriana -- Cornejo-Castillo, Francisco M -- Costea, Paul I -- Cruaud, Corinne -- d'Ovidio, Francesco -- Engelen, Stefan -- Ferrera, Isabel -- Gasol, Josep M -- Guidi, Lionel -- Hildebrand, Falk -- Kokoszka, Florian -- Lepoivre, Cyrille -- Lima-Mendez, Gipsi -- Poulain, Julie -- Poulos, Bonnie T -- Royo-Llonch, Marta -- Sarmento, Hugo -- Vieira-Silva, Sara -- Dimier, Celine -- Picheral, Marc -- Searson, Sarah -- Kandels-Lewis, Stefanie -- Tara Oceans coordinators -- Bowler, Chris -- de Vargas, Colomban -- Gorsky, Gabriel -- Grimsley, Nigel -- Hingamp, Pascal -- Iudicone, Daniele -- Jaillon, Olivier -- Not, Fabrice -- Ogata, Hiroyuki -- Pesant, Stephane -- Speich, Sabrina -- Stemmann, Lars -- Sullivan, Matthew B -- Weissenbach, Jean -- Wincker, Patrick -- Karsenti, Eric -- Raes, Jeroen -- Acinas, Silvia G -- Bork, Peer -- New York, N.Y. -- Science. 2015 May 22;348(6237):1261359. doi: 10.1126/science.1261359.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Structural and Computational Biology, European Molecular Biology Laboratory, Meyerhofstrasse 1, 69117 Heidelberg, Germany. sunagawa@embl.de karsenti@embl.de jeroen.raes@vib-kuleuven.be sacinas@icm.csic.es bork@embl.de. ; Structural and Computational Biology, European Molecular Biology Laboratory, Meyerhofstrasse 1, 69117 Heidelberg, Germany. ; Department of Microbiology and Immunology, Rega Institute, KU Leuven, Herestraat 49, 3000 Leuven, Belgium.

Description: eggNOG is a public resource that provides Orthologous Groups (OGs) of proteins at different taxonomic levels, each with integrated and summarized functional annotations. Developments since the latest public release include changes to the algorithm for creating OGs across taxonomic levels, making nested groups hierarchically consistent. This allows for a better propagation of functional terms across nested OGs and led to the novel annotation of 95 890 previously uncharacterized OGs, increasing overall annotation coverage from 67% to 72%. The functional annotations of OGs have been expanded to also provide Gene Ontology terms, KEGG pathways and SMART/Pfam domains for each group. Moreover, eggNOG now provides pairwise orthology relationships within OGs based on analysis of phylogenetic trees. We have also incorporated a framework for quickly mapping novel sequences to OGs based on precomputed HMM profiles. Finally, eggNOG version 4.5 incorporates a novel data set spanning 2605 viral OGs, covering 5228 proteins from 352 viral proteomes. All data are accessible for bulk downloading, as a web-service, and through a completely redesigned web interface. The new access points provide faster searches and a number of new browsing and visualization capabilities, facilitating the needs of both experts and less experienced users. eggNOG v4.5 is available at http://eggnog.embl.de .

Description: Microbial communities populate most environments on earth and play a critical role in ecology and human health. Their composition is thought to be largely shaped by interspecies competition for the available resources, but cooperative interactions, such as metabolite exchanges, have also been implicated in community assembly. The prevalence of metabolic...

Description: We developed a comprehensive resource for the genome-reduced bacterium Mycoplasma pneumoniae comprising 1748 consistently generated ‘-omics’ data sets, and used it to quantify the power of antisense non-coding RNAs (ncRNAs), lysine acetylation, and protein phosphorylation in predicting protein abundance (11%, 24% and 8%, respectively). These factors taken together are four times more predictive of the proteome abundance than of mRNA abundance. In bacteria, post-translational modifications (PTMs) and ncRNA transcription were both found to increase with decreasing genomic GC-content and genome size. Thus, the evolutionary forces constraining genome size and GC-content modify the relative contributions of the different regulatory layers to proteome homeostasis, and impact more genomic and genetic features than previously appreciated. Indeed, these scaling principles will enable us to develop more informed approaches when engineering minimal synthetic genomes.

Description: Despite the high abundance of Archaea in the global ocean, their metabolism and biogeochemical roles remain largely unresolved. We investigated the population dynamics and metabolic activity of Thaumarchaeota in polar environments, where these microorganisms are particularly abundant and exhibit seasonal growth. Thaumarchaeota were more abundant in deep Arctic and Antarctic...

Description: The availability of microbial genomes has opened many new avenues of research within microbiology. This has been driven primarily by comparative genomics approaches, which rely on accurate and consistent characterization of genomic sequences. It is nevertheless difficult to obtain consistent taxonomic and integrated functional annotations for defined prokaryotic clades. Thus, we developed proGenomes, a resource that provides user-friendly access to currently 25 038 high-quality genomes whose sequences and consistent annotations can be retrieved individually or by taxonomic clade. These genomes are assigned to 5306 consistent and accurate taxonomic species clusters based on previously established methodology. proGenomes also contains functional information for almost 80 million protein-coding genes, including a comprehensive set of general annotations and more focused annotations for carbohydrate-active enzymes and antibiotic resistance genes. Additionally, broad habitat information is provided for many genomes. All genomes and associated information can be downloaded by user-selected clade or multiple habitat-specific sets of representative genomes. We expect that the availability of high-quality genomes with comprehensive functional annotations will promote advances in clinical microbial genomics, functional evolution and other subfields of microbiology. proGenomes is available at http://progenomes.embl.de .
