16S rRNA Gene Sequencing Service
Introduction The 16S rRNA gene is a highly conserved component of the transcriptional machinery of all DNA-based life forms and thus is highly suited as a target gene for sequencing DNA in samples containing up to thousands of different species. 16S rRNA gene sequencing is commonly used for identification, classification and quantitation of microbes in complex biological mixtures such as environmental samples like water, soil or air, and microbiome samples such as milk or feces. Additionally, with the multiplexing of many samples and high depth of coverage afforded by today’s next-gen platforms, we can now analyze samples from comprehensive time series to quantify microbial community dynamics across many sites, or produce detailed 3D maps of microbial communities, as well as explore whether changes in rare or abundant species are associated with health and disease. Conveniently, the 16S ribosomal RNA gene consists of both highly conserved and variable regions. Universal PCR primers can be designed to target the conserved regions of 16S making it possible to amplify the gene in a wide range of different microorganisms from a single sample. While the conserved region makes universal amplification possible, subsequent sequencing of the variable regions allows discrimination between specific microorganisms such as bacteria, archaea and microbial eukarya. LC Sciences offers a comprehensive 16S ribosomal RNA gene sequencing service for identification and classification of species in microbial samples. LC Sciences has developed a dual zone amplification strategy, targeting the V3 and V4 variable regions. Sample bar-coding enables multiplexing of hundreds of different samples in a single sequencing run, keeping per sample costs low. Sequencing is performed on the industry leading Illumina MiSeq platform and extensive data analysis is provided including: sequencing data output statistics, sequence clustering into operational taxonomic units or OTUs, diversity analysis, classification and abundance analysis. An important distinction of LC Sciences’ service is that we perform the classification analysis on 7 taxonomy levels, all the way down to species level. Species level ID is enabled through the curation of several genomic databases and advanced bioinformatics. OTU Analysis An operational taxonomic unit or OTU is a measure of microbial diversity commonly used when performing 16S sequencing analysis. Sequence data is clustered into OTUs based on sequence similarity and each OTU generally represents a distinct species. OTU Venn diagrams can be used to show the unique OTUs in different subsets of sample groups. Species Accumulation Curve Statistical analysis of OTU data also generates a species accumulation curve which is a method to estimate the number of additional OTUs that may be discovered through further effort and can be an indication of adequacy or deficiency in number of samples analyzed, similar to power analysis. Diversity Analysis LC Sciences’ comprehensive service includes both Alpha and Beta diversity analysis. Alpha diversity is a measurement of the variety of organisms that inhabit a defined region or habitat. LC Sciences calculates diversity based on the Shannon, Simpson, Chao1 and observed species indices. Rarefaction Curve & Rank Abundance Curve The diversity among samples can be observed from the rarefaction curves of each sample and the rank abundance curve indicates species abundance and uniformity. Beta Diversity Analysis Beta diversity represents the explicit comparison of microbial (or other) communities based on their composition. Beta diversity metrics thus assess the differences between microbial communities. Principal Coordinates Analysis Clustering analysis of beta diversity data by the UPGMA algorithm is performed to plot a phylogenetic tree and Principal Coordinates Analysis is performed to visualize and explore similarities or dissimilarities of data. Classification of Results by Taxonomic Level The taxonomic analysis is performed by mapping OTU representative tags to the RDP, Greengenes, and NCBI 16S microbial databases. Taxonomy results are displayed in the form of area charts, heat map, and phylogenetic trees. Note the heatmaps are plotted on 7 taxonomic levels, all the way down to species level. The phylogenetic trees show the phylogenesis among species. The tree is composed of nodes that represent taxonomic units (from phylum through genus), and branches that denote the phylogenetic relation between nodes. LC Sciences comprehensive data report is presented in a user friendly HTML format for easy visualization and interpretation of your experimental results.

Molecular Data & the Microbiome
Curtis Huttenhower is an Associate Professor of Computational Biology and Bioinformatics at the Harvard T.H. Chan School of Public Health and an Associate Member at the Broad Institute. In this video Dr. Curtis Huttenhower will present a lecture titled, “Molecular Data and the Microbiome.” Video Description High-throughput sequencing has become one of many technologies that can be integrated to enable culture-independent studies of microbial communities. These include both environmental microbes, such as those that influence agriculture or water quality, as well as the human microbiome and its roles in health and disease. The multi'omic combination of amplicon sequencing, metagenomics, metatranscriptomics, and other functional molecular data is helping to bridge "parts lists" of these microbial residents with their phenotypic and environmental effects. This raises two current computational challenges: how to provide the most precise bioinformatic solutions describing microbial community systems biology, and what new applications of these integrated data types can be developed to improve population health? Dr. Huttenhower will discuss computational profiling methods for the human microbiome, which provide strain-specific microbial identification and metabolic reconstruction. In combination with microbiome-appropriate statistical tools, these can thus associate microbial features with health outcomes and covariates in human populations to better understand immune and inflammatory disease. About the Speaker Dr. Curtis Huttenhower is an Associate Professor of Computational Biology and Bioinformatics at the Harvard T. H. Chan School of Public Health and an Associate Member at the Broad Institute. He was an analysis lead in the NIH Human Microbiome Project, the "HMP2," and currently leads the Human Microbiome Bioactives Resource. His lab focuses on computational methods for functional analysis of microbial communities, as well as microbiome epidemiology to link microbial community function to public health.

Spatial and Temporal Structure in the GI Microbiota
Authors: Eric J. de Muinck, Knut E. A. Lundin, Pål Trosvik Editor: Morgan G. I. Langille Importance: The human gut microbiome is the subject of intense study due to its importance in health and disease. The majority of these studies have been based on the analysis of feces. However, little is known about how the microbial composition in fecal samples relates to the spatial distribution of microbial taxa along the gastrointestinal tract. By characterizing the microbial content both in intestinal tissue samples and in fecal samples obtained daily, we provide a conceptual framework for how the spatial structure relates to biotic interactions on the community level. We further describe general categories of spatial distribution patterns and identify taxa conforming to these categories. To our knowledge, this is the first study combining spatial and temporal analyses of the human gut microbiome. This type of analysis can be used for identifying candidate probiotics and designing strategies for clinical intervention.

Katherine Pollard: "Massive Data Sheds Light on Your Microbiome" | Talks at Google
The most influential “organ” in the human body might be made up of foreign cells—six pounds worth of microorganisms. Katherine Pollard discusses how her lab at the Gladstone Institutes uses big data and high-performance computing to study the human microbiome and learn how it influences health and disease. The human microbiome plays a role in processes as diverse as metabolism, immune function, and mental health. Yet despite the importance of this system, scientists are just beginning to uncover which microorganisms reside in and on our bodies and determine what functions they perform. The development of innovative technology and analytical methods has enabled researchers like Dr. Pollard to decode the complex interactions between our human cells and microbial brethren, and infer meaning from the staggering amounts of data 10 trillion organisms create. Katherine Pollard, PhD, is a senior investigator at the Gladstone Institutes, director of the Gladstone Convergence Zone, and a professor of epidemiology and biostatistics at UCSF.

Gabriele Berg. The Power of Networking: Studying Microbiomes for Health
The plant microbiome is a key determinant of plant health and productivity. The microbiomes associated with plants form tight networks, which revealed strong species and niche specialization. Analyzing microbiome networks from healthy and diseased plants led to the identification of health indicators and pathogen-supporting microorganisms as well. This approach thus serves to open new opportunities for future targeted biocontrol studies and could fuel progress in sustainable agriculture, such as the development of microbial inoculants as biofertilizers, biocontrol, or stress protection products. The plant microbiome has not only an impact on plant health, it also influence the human microbiome, e.g. by raw-eaten fruits, vegetables and herbs. Moreover, it can have a positive impact on the microbiome of our built environment. Taken together, plant microbial networks are powerful networks with an impact on ecohealth. Colonization by bacteria of the zone surrounding plant roots (rhizosphere) is crucial to plant productivity, with plants secreting 10-30% of total photosynthate to engineer the rhizosphere to their advantage. In spite of its importance rhizosphere colonization is poorly understood but recent advances in genome sequencing and analysis makes it possible to address this complex topic in exciting new ways. Microarray and metabolic analysis has been used to dissect the composition of the pea root secretome and map the transcriptional response of bacterial to secreted metabolites. Most recently this work has led to identification of the master regulator of attachment of Rhizobium leguminosarum to pea roots.

Jason Kralj - Standards for Microbiome and Metagenomics...
Watch this presentation on Labroots at https://www.labroots.com/virtual-event/molecular-diagnostics-2017/agenda In spite of the huge potential impact of microbiome science, current measurement capabilities are insufficient, particularly for translating discoveries and correlations observed in the lab into commercially viable products and services that improve our quality of life. Data are difficult to compare between experimenters, laboratories, or institutions. Emerging capabilities (e.g., next generation sequencing, metabolomics) are new and not fully characterized for microbiome investigations. Reference samples (i.e., for calibration or quality control) that mimic the complexity of naturally occurring communities are not available. Bioinformatic analysis packages and reference databases remain incomplete. At NIST, we are improving microbiome science and supporting the National Microbiome Initiative by developing standards for microbiome measurements that will enable federal, academic, and industry labs to reliably reproduce and advance each other's results. Microbiome standards will support research investigations and commercial translation of microbiome science by providing measurement assurance tools: standardized protocols, reference materials, validated measurements and critically evaluated reference data.

Special microbes make anti-obesity molecule in the gut
Microbes may just be the next diet craze. Researchers have programmed bacteria to generate a molecule that, through normal metabolism, becomes a hunger-suppressing lipid. Mice that drank water laced with the programmed bacteria ate less, had lower body fat and staved off diabetes — even when fed a high-fat diet — offering a potential weight-loss strategy for humans.

What Is Irritable Bowel Syndrome?
I’m sure you know the feeling, even though you may not know the name. Irritable bowel syndrome or Spastic Colon is one of the most common intestinal disorders. Most doctors and patients find it hard to clearly define just what Irritable Bowel Syndrome is. It used to be a diagnosis of exclusion where the doctor would finally label your symptoms as IBS when they couldn’t think of anything else to call it,But IBS research has advanced so much in the last 5 years that it has cleared the path to a much fuller understanding of the cause and effects of IBS.

Does Candida Cause Acne Rosacea
Discover if there is a link between candida and acne rosacea. Can candida cause severe acne rosacea? Greetings. New Zealand naturopath, Eric Bakker. Author of Candida Crusher and formulator of the Canxida range of supplements. Thanks for checking out my video. Question here by Pasqual from Quebec, Canada. Pasqual's asking me, "Eric, does Candida cause acne rosacea?" Pasqual, there is definitely a link between Candida and acne rosacea. That's been proven now. I've looked at many different kinds of studies from PubMed, InBase, and CINAHL, and I've had a really good look through different databases online after I got your email. Also, in Singapore, there is a skin clinic there where they've found a very clear-cut link between the gut microbiota to cleaning up the gut with patients and the skin. I've noticed this in my clinic now for probably over 20 years. I've treated over a thousand cases of psoriasis successfully, but I also treat a lot of acne rosacea and many other different kinds of skin conditions. There is a huge link between the gut and the skin. A very interesting case I recently had was a male patient from Portugal, a 38-year-old male with seriously bad acne rosacea. Basically, I didn't even look at the skin. I just treated the gut and we had an outstanding result. We found that this guy had incredible amounts of Candida albicans, Candida glabrata, and also Blastocystis hominis. And once we cleared up these things and we found that with pre and post stool testing, we had an incredibly high success rate with eradication, the skin entirely cleared up. He's a very lovely man and now he excitedly Skyped me recently. He said, "I've now got a girlfriend. I've got a Swedish girlfriend. I'm so excited." I don't know if you've seen how bad acne rosacea can get. When you've got bad acne rosacea, you've got no self-confidence. For this guy after 10 or 15 years to get his skin finally cleared up, his confidence was like in overdrive and he was so excited to tell me all about his girlfriend. How did this association occur? Well, in Singapore at the Dermoclinic what they found out was that Candida could actually produce different kinds of chemicals that upregulate or stimulate the production of inflammatory cytokines. So what that means in normal English is Candida can stir the hell out of the immune system and the immune system, in turn, then can create chemicals that can create dilation of the skin, the blood vessels, flushing, redness, irritation, infections, all kinds of things can occur. There is certainly a link there. If anyone is watching this who has got acne rosacea, my strong advice for you is (A) improve the upper digestion because many people with acne rosacea have got hypochlorhydria or underactive stomach, (B) ensure that the pancreas is working properly and it will work better when the stomach is working better, (C) make sure that you've cleared up food allergies or food intolerances. Sometimes it's worthwhile doing an ELISA test, so an IgG, IgE food allergy test. The best one, I think, is from US Biotech in Seattle. It's s serum test, (D) if you've got a really bad problem like my patient in Portugal, get a proper stool test done, a comprehensive one to assess what kind of bugs you've got in the gut. So then, we can go about cleaning up the gut and (E) kick back and enjoy life. Because if you do all of those things properly, there is a big chance we can clear up the acne rosacea profoundly and you can lead a relatively normal life with a good amount of self-esteem. I hope that answers your question, Pasqual. In my opinion, there is a massive link between acne rosacea and a yeast infection. Don't forget, while I've got your attention, to please subscribe to my channel. Check out my 1,000+ articles at yeastinfection.org and make sure you do my quiz. I've got the world's best online quiz. I've also got a very nice supplement for people with acne rosacea. It's called Canxida Restore. It's a great probiotic enzyme formula. Be sure to take my antifungal Canxida Remove and Canxida Restore. These two products are going to help you hugely with acne rosacea, especially if you've done some stool testing and been checked out and checked positive to have bugs.

The Human Microbiome: Emerging Themes at the Horizon of the 21st Century (Day 3)
The Human Microbiome: Emerging Themes at the Horizon of the 21st Century (Day 3) Air date: Friday, August 18, 2017, 8:15:00 AM Category: Conferences Runtime: 04:59:15 Description: The 2017 NIH-wide microbiome workshop will strive to cover advances that reveal the specific ways in which the microbiota influences the physiology of the host, both in a healthy and in a diseased state and how the microbiota may be manipulated, either at the community, population, organismal or molecular level, to maintain and/or improve the health of the host. The goal will be to seek input from a trans-disciplinary group of scientists to identify 1) knowledge gaps, 2) technical hurdles, 3) new approaches and 4) research opportunities that will inform the development of novel prevention and treatment strategies based on host/microbiome interactions over the next ten years.

Metaproteomics For The Future: ASMS 2017 presentation on metaproteomics
Metaproteomics For The Future: Democratizing functional analysis of microbiomes via community-based informatics development and dissemination. The impact of microbiomes (genes expressed by microbiota) on human health and environment is getting increasingly appreciated. Microbiome research is dominated by taxonomic-centered estimations using metagenomic 16S rRNA-based approaches. Functional characterization with metaproteomics analysis (study of expressed microbial proteins) stands to more accurately and mechanistically describe microbial responses in these dynamic systems. However, metaproteomic informatics remains an emerging research area, which requires numerous software tools to manage, analyze and interpret data. Consequently, this growing field will need deliberate, international coordination to create the kinds of robust software that will facilitate metaproteomic informatics. Here, we propose a community-based and innovative approach that we believe will result in robust analytical workflows and will help in advancing and broadening the reach of metaproteomics. A collaborative informatics initiative to develop a suite of validated software and robust Galaxy workflows for advanced metaproteomics informatic analysis.

Barriers to open sharing of research data using social tools?  Q and A with Dr. Pieter Dorrestein
In this clip, Dr. Pieter Dorrestein discusses the challenge of encouraging researchers to share data openly using collaborative tools. Dr. Dorrestein is professor at the Skaggs School of Pharmacy and Pharmaceutical Sciences at the University of California at San Diego. He delivered a lecture at NIH in April 2015 on “Social Networks For Molecular Analysis.” Watch his lecture here: http://videocast.nih.gov/Summary.asp?... Q: Have there been barriers to researchers sharing their data openly? A: So yes, I think the scientific community has been trained to be quite afraid of sharing data beforehand. There’s a couple of ways that you can limit that concern. One is if you upload raw data you can still make cross-correlations with other data sets. There’s limited context with what’s put in and so. But our idea is with our tool is to actually make the analysis so powerful that if you don’t make your data publicly accessible, you can spend many more man-years to figure out the same thing. And so by making it publicly accessible, you actually get way more information than we would otherwise be able to get. And so that’s a real incentive for a lot of people to make the data publicly accessible. And I think it’s well, should it be mandated? Probably not. It really should be driven from the standpoint that these tools are so useful that they will want to use it. Now if you look at the breakdown, however, of people who are using it, you can clearly see that this younger generation is not afraid to share. They don’t have this fear of being scooped. They know how to work collaboratively, and that to me is really an exciting direction that the scientific community is going to. We’re no longer isolated silos. No, we work as a group even though each individual person can put out their own publication, we can still cross-learn from all the information that was provided.

20180409 4 OTUs from 16S rRNA
Slides for this lecture can be found at https://drive.google.com/open?id=1aAXuC7__6C00Xprt-YjMS7lbGV8zGYaE This lecture on amplicon sequencing informatics was the second of three to describe the bioinformatics of Next-Generation Sequencing (NGS) for the B.Sc. Honours program in Biotechnology at the University of the Western Cape. Microbiome research frequently relies upon an assessment of alpha and beta diversity of species, as approximated by Operational Taxonomic Units (OTUs). OTUs, in turn, represent sets of 16S rRNA sequences that are 97% similar to each other, clustered from amplicon sequencing by software such as MOTHUR, QIIME, and UPARSE. These clusters can then be matched to 16S rRNA sequences that have been associated with taxonomic information, sometimes to the genus or species level. This association comes from the use of a 16S database such as RDP, SILVA, or Greengenes. Rarefaction curves can then evaluate the extent to which sequencing represents a comprehensive catalog of species for the sample.

Stephen Porges: The Polyvagal Theory & The Vagal Nerve – #264
Stephen Porges comes to Bulletproof Radio to share his pioneering research on the vagus nerve, how the cues it receives play a major role in stress, social behavior and the nervous system and some tips on how to improve its response. Dr. Porges is a Distinguished University Scientist at Indiana University where he directs the Trauma Research Center in the Kinsey Institute. He is Professor of Psychiatry at the University of North Carolina, Professor Emeritus at the University of Illinois at Chicago, where he directed the Brain-Body Center in the Department of Psychiatry, and Professor Emeritus at the University of Maryland, where he chaired the Department of Human Development and directed the Institute for Child Study. In 1994 he proposed the Polyvagal Theory, a theory that links the evolution of the mammalian autonomic nervous system to social behavior and emphasizes the importance of physiological state in the expression of behavioral problems and psychiatric disorders.

Pathways To Cures:The Microbiome
What is the Microbiome? Approximately 90% of the cells that are on and inside your body aren't you. Those cells are the trillions of microscopic bacteria and viruses that make up the human microbiome. The gut's microbiome contains a mix of enormously complex bacteria, viruses and fungi -- but only a limited number of these microbial agents have been identified and their functions are still largely unknown. Learn why the Microbiome is important to cures at: www.ccfa.org.
