Introduction Communities, or species assemblages, are a fundamental unit of ecological organization, just as cell or tissue types are fundamental units of study for molecular biology and physiology.

Microbiomes: unifying animal and plant systems through the lens of community ecology theory

Originally developed for macroorganismal systems (Clements, 1916), many community ecology theories attempt to elucidate complex species interactions across space and time. Increasingly, these concepts are being applied to the study of some of our planet’s most complex and intimate communities—host-associated microbiomes. Both plants and animals are colonized by an astonishing number of symbiotic microbes (Raaijmakers et al., 2008; Zilber-Rosenberg and Rosenberg, 2008; Rodriguez et al., 2009; Lecuit and Eloit, 2013), and recent advances in sequencing technologies and data processing are finally affording researchers the opportunity to uncover the cryptic diversity and functions of these microbiomes (Zimmerman et al., 2014).

Le microbiote intestinal : un organe à part entière - PARLONS SCIENCES

Le premier contact avec des bactéries s’effectue lors de l’accouchement. La composition du microbiote varie fortement dans les premiers mois de la vie au gré du passage des bactéries dans notre tube digestif. La diversité des bactéries présentes dans notre tube digestif augmente progressivement et c’est vers l’âge de deux ans que le microbiote se stabilise pour être fonctionnellement proche de celui retrouvé à l’âge adulte. Cette stabilité est néanmoins fragile car le microbiote est soumis à de nombreux facteurs pouvant le modifier tels qu’un régime alimentaire trop gras ou une prise fréquente d’antibiotiques. La répartition des bactéries le long du tube digestif n’est pas homogène. En pratique, il est difficilement envisageable de récupérer les bactéries intestinales directement dans le côlon car cette procédure est invasive pour le patient et nécessite une anesthésie.

Gout diet: Fruit and vegetables could cure painful form of arthritis

They said following a high fibre diet combats the razor sharp crystals that form in and around the joints and under the skin. Gout is caused by too much uric acid in the bloodstream, which causes urate crystals to start to form in and around the joints and under the skin. The condition affects about one in 100 people, with men two to three times more likely to be affected than women.

Stress, Depression and Anxiety Are All Alleviated by Probiotics. There are over 400 species of bacteria in your belly right now that can be the key to health or disease.

Stress, Depression and Anxiety Are All Alleviated by Probiotics

The genomes of the bacteria and viruses of the human gut alone are thought to encode 3.3 million genes. Published in The Journal of Alternative and Complementary Medicine, the study reviewed the results of seven previous studies which tested for symptoms in over 300 healthy volunteers both before and after supplementation with a probiotic. Researchers from Griffith University in Queensland, Australia, wrote: “Interest in the gut-brain axis and emerging evidence that the intestinal microbiota can influence central nervous system function has led to the hypothesis that probiotic supplementation can have a positive effect on mood and psychological symptoms such as depression and anxiety.

“Although several human clinical trials have investigated this, results have been inconsistent. Seven studies met the inclusion criteria and provided data for nine comparisons. 1. Coming of age: ten years of next-generation sequencing technologies : Nature Reviews Genetics. Since the completion of the human genome project in 2003, extraordinary progress has been made in genome sequencing technologies, which has led to a decreased cost per megabase and an increase in the number and diversity of sequenced genomes.

Microbiome may be next big frontier in medicine

The human gut microbiome — which includes the community of trillions of bacteria living within our intestines — has been called one of the next big frontiers in medicine. In recent years, a growing body of research has shown that the bacteria in our gut exert a powerful influence on our immune and endocrine systems, brain health, mood and cognitive function, and other key biological processes. We know that the balance of good and bad bacteria in the gut can keep us healthy — or can contribute to disease. Now, the next step for this exciting medical frontier is learning how to leverage the power of the microbiome to treat disease.

January High Five – Writing and Re-writing History – Altmetric

On a monthly basis, my High Five posts examine a selection of the most popular research outputs Altmetric has seen attention for that month. This month’s theme is changing history. The top scientific papers this month according to all have big implications for our understanding of human, and celestial, history. Pluto may no longer be a planet, but another “planet nine” may lurk beyond it. Sorry, it turns out you are human after all. Sorry, it turns out you are human after all It’s often said that the bacteria and other microbes in our body outnumber our own cells by about ten to one.

Sorry, it turns out you are human after all

But that’s a myth that should be forgotten according to a new paper – the ratio between resident microbes and human cells is more likely to be one-to-one. The myth arises from a rough estimate made in 1972 which has persisted ever since. Of course, this only applies to cells – the number of viruses in your body vastly outnumber all the cells.

Microbiome remains malleable after birth. The GLP aggregated and excerpted this blog/article to reflect the diversity of news, opinion and analysis. Trillions of bacteria – and other tiny single-celled organisms, such as archaea and protozoa – live in our bodies, largely in our gut. They’re estimated to outnumber the actual cells of “our” bodies. This ecosystem of tiny creatures we carry around with us is thought to have profound effects on our health. The Human Microbiome Project says that the makeup of an animal’s microbiome has an impact on its immune systems, heart health, and behaviour, among other things.

Your Microbes, Yourself – Pacific Standard. An immunotoxicologist by profession, Dietert speaks about these cutting-edge scientific matters with the zeal of the convert. Indeed, near the end of the book, we learn that he had something of a life-changing experience a few years ago. While visiting Germany for less than a week and eating whatever conference catering provided, Dietert discovered that he was losing weight and enjoying noticeable relief from two chronic conditions: gastric reflux and sinusitis. (The weight loss was all the more unusual because he was sitting in conferences for almost the entire trip.) Different Strokes: Blending Microbiology and Art.

Comment les fibres nous protègent du diabète et de l’obésité. Il est bien connu des chercheurs qu’une alimentation riche en fibres protège l’organisme de l’obésité et du diabète. Néanmoins, les mécanismes à l’œuvre leur échappaient depuis une vingtaine d’années. Une équipe franco-suédoise comprenant des chercheurs du CNRS, de l’Inserm et de l’Université Claude Bernard Lyon 1 (Unité Inserm 855 « Nutrition et cerveau ») vient d’élucider ce mécanisme dans lequel sont impliquées la flore intestinale et la capacité de l’intestin à produire du glucose entre les repas.

Ces résultats, publiés dans la revue Cell le 9 janvier 2014, précisent en outre le rôle de l’intestin et de ses microorganismes associés dans le maintien de la glycémie. Ils permettront aussi de proposer de nouvelles recommandations nutritionnelles afin de se prémunir du diabète et de l’obésité. Trop de gras déséquilibre rapidement la flore intestinale. How Your Gut Bacteria Influence What You Eat. Diet, the gut microbiome, and colorectal cancer: are they linked? New Rochelle, NY, December 9, 2016--Recent evidence from animal models suggests a role for specific types of intestinal bacteria in the development of colorectal cancer (CRC). If a microbial imbalance in the gut could actively contribute to CRC in humans, dietary-based therapeutic interventions may be able to modify the composition of the gut microbiome to reduce CRC risk, as discussed in a review article published in BioResearch Open Access, a peer-reviewed open access journal from Mary Ann Liebert, Inc., publishers.
