Molecular Psychiatry - The microbiome regulates amygdala-dependent fear recall. Molecular Psychiatry advance online publication 16 May 2017; doi: 10.1038/mp.2017.100 A E Hoban1,2, R M Stilling1,2, G Moloney2, F Shanahan1, T G Dinan1,3, G Clarke1,3 and J F Cryan1,2 Top of page Introduction Recently, we have shown that the amygdala transcriptome in GF mice is widely dysregulated and shows features of neuronal hyperactivity at the gene expression level.21 Coinciding with these findings, GF animals display greater amygdalar volume with increased excitatory spine density in the basolateral nuclei,22 demonstrating that the presence of the host microbiome critically regulates the morphology and transcriptional programming within the amygdala.

This is clearly beneficial to the F-plasmid, since its genes get replicated, but why is it useful to the bacteria?

Bacteria - Pili

The F-plasmid often contains useful genes that deal with stressful situations that have recently arisen, for will spread this resistance to other bacteria. Since the F-plasmid can integrate into the host's chromosomal DNA it can, upon leaving, take away copies of host genes with it, these genes may be of use to the recipient cell.

Explorer. What kind of results will I get?


After your sample has been analyzed, you get to be an explorer and learn about the vast rainforest of bacteria in your body. Logging in to, you'll see detailed information on each of these bacteria - what their names are, how many of each kind there are, what their functions are in the body. You may find yourself curious to compare your results with the aggregate results of everyone who's done the test, and with specific groups of people.

The first thousand days – intestinal microbiology of early life: establishing a symbiosis - Wopereis - 2014 - Pediatric Allergy and Immunology. Abstract The development of the intestinal microbiota in the first years of life is a dynamic process significantly influenced by early-life nutrition.

The first thousand days – intestinal microbiology of early life: establishing a symbiosis - Wopereis - 2014 - Pediatric Allergy and Immunology

Pioneer bacteria colonizing the infant intestinal tract and the gradual diversification to a stable climax ecosystem plays a crucial role in establishing host–microbe interactions essential for optimal symbiosis. This colonization process and establishment of symbiosis may profoundly influence health throughout life. Recent developments in microbiologic cultivation-independent methods allow a detailed view of the key players and factors involved in this process and may further elucidate their roles in a healthy gut and immune maturation. Aberrant patterns may lead to identifying key microbial signatures involved in developing immunologic diseases into adulthood, such as asthma and atopic diseases. SUPERFLEX/Tools.

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

Malgré la cohabitation avec ces milliards de bactéries à l’âge adulte, le nouveau né est stérile à la naissance. 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. 1. Microbiota – the forgotten organ. Back to overview Today, the idea that gut bacteria affects a person’s health is not new. Most of us know that these microbes influence digestion, allergies, and metabolism. New books explaining which diet will lead to optimum bacterial health are published regularly and most of us have at least heard one time about its importance for our health. The gut flora as a forgotten organ. Gout diet: Fruit and vegetables could cure painful form of arthritis. Eating plenty of fruit and vegetables can reduce the risk of agonising gout attacks, as it can affect gut bacteria, experts have said.

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. However the condition can sometimes affect post-menopausal women. 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.
