Wild Mouse Gut Microbiota Promotes Host Fitness and Improves Disease Resistance
Scientists from the NIH’s National Institute of Diabetes and Digestive and Kidney Diseases led research finding that transferring the gut microbes from wild mice to laboratory mice promoted fitness and significantly improved responses to an otherwise lethal flu virus infection and to colorectal cancer. By making lab mice more closely mirror real-world mice, the approach may improve the odds of success as research moves from mouse to man. The method could also help advance studies in metabolism, behavior, and endocrinology. The results published in Cell: www.cell.com/cell/fulltext/S0092-8674(17)31065-6
Lora Hooper (UT Southwestern) 1: Mammalian gut microbiota: Mammals and their symbiotic gut microbes
https://www.ibiology.org/immunology/gut-microbiota/ Overview: Dr. Hooper studies how the gut microbiota changes during illness or disease and how it influences our ability to fight infections. In part 2, Hooper explains how a healthy gut microbes induce a host protein called RegIIIγ which helps to protect the host from infection by pathogenic gram-positive bacteria. Detailed description: In this lecture, Dr. Hooper introduces us to the fascinating world of human microbiota; the microorganisms that live within our bodies. Although we may think that most bacteria are harmful, Hooper provides ample evidence that symbiotic gut microbes are important to good human health. Her lab is interested in understanding how the microbiota changes during illness or disease and how it influences our ability to fight infections. Using germ-free mice, they were able to demonstrate that a healthy microbiota can shape development of the host immune system and provide protection against dangerous infections like salmonella. In the second part of her talk, Hooper explains how the balance of organisms in the microbiota is maintained. By comparing DNA microarray data from normal mice and germ-free mice, Hooper’s lab was able to look for genes induced by the microbiota. They identified RegIIIγ, an important protein involved in the protection against pathogenic bacteria. They showed that RegIIIγ forms pore complexes in the membranes of gram-positive bacteria and kills them. In mice and humans, the intestinal epithelium is coated with a layer of mucus. Typically, there is a gap between gut bacteria, which are found in the outer part of the mucus layer, and the epithelial cells. Hooper’s lab showed that RegIIIγ helps to maintain this gap by preventing gram-positive bacteria from colonizing the intestinal epithelial surface. This, in turn, prevents infection of the host. Speaker Biography: Although she always was interested in science, Lora Hooper’s love for biology started after taking an introductory class at Rhodes College in Memphis, TN where she was an undergraduate. Hooper continued her graduate education in the Molecular Cell Biology and Biochemistry Program at Washington University in St. Louis where she joined Dr. Jacques Baenziger's lab. For postdoctoral training, she stayed at Washington University, in the lab of Jeffrey Gordon, where she began her studies of the interaction between gut bacteria and host cells and discovered that bacteria have the capacity to modify carbohydrates important for cell signaling. Currently, Hooper is a Professor at The University of Texas Southwestern Medical Center and a Howard Hughes Medical Institute Investigator. She has established one of the handful of mouse facilities that have the capacity to breed germ-free mice. Using these mice, her lab explores the symbiotic relationship between a host and its microbiota with the aim of providing insight into human health. Hooper was a recipient of the Edith and Peter O’Donnell Awards in 2013 and in 2015 she was elected to the National Academy of Sciences.

Human Derived Gut Microbiota Modulates Colonic Secretion in Mice …  – Bhattarai et al. (2017)
Serotonin (5-hydroxytryptamine, 5-HT), an important neurotransmitter and a paracrine messenger in the gastrointestinal (GI) tract, regulates intestinal secretion by its action primarily on 5-HT3 and 5-HT4 receptors. Recent studies highlight the role of gut microbiota in 5-HT biosynthesis. In this study we determine if human-derived gut microbiota affect host secretory response to 5-HT and 5-HT receptor expression. We used proximal colonic mucosa-submucosa preparation from age matched Swiss Webster germ free (GF) and humanized (HM; ex-GF colonized with human gut microbiota) mice. 5-HT evoked a significantly greater increase in short circuit current (ΔIsc) in GF compared to HM mice.

Dan Littman (NYU / HHMI) 2: Shaping of Immune Responses by the Microbiota
https://www.ibiology.org/immunology/th17 Th17 cells are important in our protective immune response to bacteria and fungi. They also can exist, however, in a pathogenic form that causes autoimmune disease. In his first lecture, Dan Littman discusses the opposing roles of Th17 cells. They protect mucosal surfaces from infection with bacteria and fungi, but they can also cause autoimmune inflammation. Using a mouse model of autoimmunity called experimental autoimmune encephalitis (EAE), Littman and his lab have shown that there are two types of Th17 cells. Non-pathogenic Th17 cells are induced by the microbiota and protect barrier surfaces, while pathogenic Th17 cells are induced by the presence of IL-23, likely the result of inflammation elsewhere in the body. Both types Th17 cells secrete the cytokines IL-17A, IL-17F and IL-22, however, pathogenic Th17 cells also secrete interferon gamma (IFNγ) which induces further inflammation and autoimmune disease. In the last 10 years, several classes of innate lymphoid cells have been found to share similar cytokine profiles to Th17 cells and these cells appear to be another important layer in protecting surfaces in the gut and lung from infection. In his second talk, Littman explains that different commensal microbes in our gut elicit different T cell responses - either pathogenic or non-pathogenic. His lab is beginning to identify the pathogens and decipher the pathways that determines the host T cell response. This research has important clinical relevance since a cancer patient’s microbiota may help determine their response to chemotherapy. Microbiota that induce non-pathogenic Th17 cells are protective against autoimmunity but may decrease anti-tumor immunity, while microbiota that contribute to autoimmunity may enhance anti-tumor T cell responses. Speaker Biography: Dan Littman is the Helen and Martin Kimmel Professor of Molecular Immunology in the Department of Pathology and a professor in the Department of Microbiology at the Skirball Institute of Biomolecular Medicine of New York University School of Medicine. He is also an Investigator of the Howard Hughes Medical Institute. Littman discovered the excitement of science while he was an undergraduate student at Princeton University. He went on to receive his M.D. and Ph.D. from Washington University in St. Louis. As post-doc in Richard Axel’s lab at Columbia University, Littman isolated the genes for CD8 and CD4, molecules involved in T lymphocyte development. Littman then joined the faculty of the University of California, San Francisco where he was one of the first scientists to recognize that HIV infects T helper cells by binding to CD4. Since 1995, Littman has been based at NYU. Littman’s lab has continued to study the development and differentiation of T lymphocytes. They are interested in understanding how a normal protective immune response differs from a pathogenic response such as that found in inflammation and autoimmune disease. Currently, they are also investigating the importance of the microbiome in influencing immunity. Littman is a member of the National Academy of Sciences and a fellow of the American Academy of Arts and Science and the American Academy of Microbiology. His groundbreaking work has been recognized with many prizes including the 2004 New York City Mayor’s Award for Excellence in Science and Technology, the 2013 Ross Prize in Molecular Medicine, and the 2016 Vilcek Prize in Biomedical Science amongst others.

Fat Mice Linked to Gut Microbes
Science News reports new research in rodents suggests gut microbes cause obesity by sending messages via the vagus nerve to pack on pounds. In the June 9th issue of Nature magazine, researchers report bacteria in the intestines produce a molecule called acetate, which works through the brain and nervous system to make rats and mice fat. Yale University endocrinologist Gerald Shulman led the study. He said acetate also increases levels of a hunger hormone called ghrelin, which could lead animals and people to eat even more. Biochemist Jonathan Schertzer of McMaster University in Hamilton, Canada, called the paper a “tour-de-force." https://www.sciencenews.org/article/obesity%E2%80%99s-weight-gain-message-starts-gut http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

How The Gut Microbiota Affects Our Health with Dr. Erica & Dr. Justin Sonnenburg
Dr. Justin Sonnenburg is an associate professor of microbiology and immunology at Stanford and Dr. Erica Sonnenburg is a senior research scientist in the Sonnenburg lab where they the research many aspects the interaction between diet with the 100 trillion or so bacteria in the gut (specifically the colon) and how this impacts the health of the host (which in this case is a laboratory research mouse). In this episode we discuss the pivotal role fiber plays in fueling good bacteria in the gut to produce compounds that regulate the immune system including increasing the number of T regulatory cells, which are specialized types of immune cells that keep the immune system in check and prevent autoimmune responses, and how these compounds also increase other types of blood cells in the body in a process known as hematopoiesis. We also talk about how the lack of fiber in the typical American diet actually starves these good bacteria of their food. This has an effect not only on the immune system and autoimmune diseases but also results in the breakdown of the gut barrier, which leads to widespread inflammation and inflammatory diseases. Lastly, in this podcast, Dr. Erica Sonnenburg talks about how C-sections, have a negative effect on the infant’s gut due to the lack of exposure to bacteria present in the mother’s vaginal canal, and how the use of formula deprives the infant not only from the good bacteria present in Mom’s gut but also from special carbohydrates in breast milk that are good for the infant gut flora known as HMOs or human milk oligosaccharides. ▶︎ Get the show notes! https://www.foundmyfitness.com/episodes/the-sonnenburgs Links related to the Sonnenburgs: ▶︎ http://sonnenburglab.stanford.edu/ ▶︎ http://www.facebook.com/thegoodgut ▶︎http://www.amazon.com/gp/product/1594206287/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=1594206287&linkCode=as2&tag=foun06-20&linkId=IOKAGDTRCL47XQN6 Links related to FoundMyFitness: ▶︎ Join my weekly newsletter: http://www.foundmyfitness.com/?sendme=nutrigenomics ▶︎ Crowdfund more videos: http://www.patreon.com/foundmyfitness ▶︎ Subscribe on YouTube: http://www.youtube.com/subscription_center?add_user=foundmyfitness ▶︎ Subscribe to the podcast: http://itunes.apple.com/us/podcast/foundmyfitness/id818198322 ▶︎ Twitter: http://twitter.com/foundmyfitness ▶︎ Facebook: http://www.facebook.com/foundmyfitness ▶︎ Instagram: http://www.instagram.com/foundmyfitness

Lee Kerkhof│The Mouse Microbiome and the MinION
The human/microbiome promises to be a new avenue to treat disease. However, we need model systems and research tools to understand the mechanistic drivers for the mammalian microbiome beyond current correlative metagenomics studies. Rutgers researchers are working with the MinION and mouse models to study how host genetics/exercise behaviour/ and exposure to evironmental toxins influences the host response to aging/obesity/and inflammation through the microbiome. In one set of experiments, diet/exercise can be shown to structure the gut microbiome in male/female mice. We are also investigating a knock-out mouse for adenylyl cyclase as a longevity model to aging and exercise pre-conditioning. In other experiments, ozone expose can lead to blooms of opportunistic pathogens in mouse lungs. Additional studies in two mouse knock-outs in which the inflammatory response to ozone is specifically altered are being used to monitor the mechanisms controlling lung microbiomes.

Utilizing Gnotobiotic Mice to Understand the Role of the Microbiome in Murine Disease Models
The environmentally exposed surfaces of mammals, such as the skin, mouth, gut, and vagina, are colonized by a diverse ecosystem of microbes. Though many of these bacteria - particularly those of the distal gut - are considered symbiotic, the microbiome has the capacity to induce both pro- and anti- inflammatory responses. Accumulating evidence suggests that a properly balanced gut microbiome is crucial for a correctly functioning immune system, and that imbalances in the microbial community of the intestine are linked to a multitude of auto-inflammatory and auto-immune diseases. This symposium will discuss the roles of the microbiome in murine models of various inflammatory disease states, and the advantages to utilizing germ-free/gnotobiotic mice when probing disease models with a microbiome component.

Exercise and gut bacteria
We’re learning what a vital role good gut bacteria play in immune health, brain health, mood, and, of course, gut health. One of the best health quotes of all time is… “Health comes from above, down, inside, out” We also know that the best way to beef up your good gut bacteria is through eating lots of different kinds of vegetables and fruits every day. But researchers have discovered yet another way to promote healthy gut bacteria: Regular exercise. Our digestive tract is home to trillions of gut bacteria that weigh about three to four pounds all together, and are made up of over a 1,000 different species and 5,000 strains. This is the very definition of a symbiotic relationship. Our body depends on these gut bacteria to: • Metabolize nutrients • Protect the intestinal wall • Produce vitamin K and short chain fatty acids (SCFA), which are important for immune health • Maintain health of the digestive tract • Regulate immunity • Prevent inflammation • Promote good brain health and function - infant many studies are even finding that Parkinsons may actually start in the gut and work its way up the vagus nerve into the brain. But that is another post for another blog. Very interesting stuff though. As our understanding of healthy gut bacteria evolves, so does the information on how to cultivate your own “microbiome” while inhibiting overgrowth of “bad” bacteria that are infectious and inflammatory. This imbalance of good and bad bacteria is often what is referred as dysbiosis - Too many bad bacteria and not enough good bacteria. Initially, fermented foods and probiotics were thought to be the main recourse for improving gut health, and they do go a long ways. But, they are not the only way. Then we learned eating a diet comprised primarily of vegetables and fruits and continually changing up the produce you eat is a great way to develop a rich and diverse gut bacteria population. Now, scientists have used both a mouse study and a human study to show regular exercise, independent of diet or other factors, also promotes healthy gut bacteria. Meaning that if you do nothing other than exercise you can beneficially change your gut bacteria. In the first study, researchers transplanted fecal material from both exercised and sedentary mice into mice with sterile guts. The activity level of the mice receiving the transplants clearly mirrored that of their donors, showing that the kind of gut bacteria we have plays a role in how inclined we are to be sedentary or active. The exercised mice recipients also showed more bacteria that produce butyrate, a short-chain fatty acid (SCFA) that promotes healthy intestinal cells, reduces inflammation, and increases energy. They also were more resistant to ulcerative colitis. N-butyrate is THE most important short chain fatty acid. In the second study, researchers tracked the composition of gut bacteria in 18 lean and 14 obese adults as they transitioned from a sedentary lifestyle, to an active one, and then back to a sedentary one. Their exercise routine consisted of 30 to 60 minutes of cardiovascular exercise three times a week for six weeks. Their diets remained the same.

Fecal transplants & why you should give a crap | Mark Davis | TEDxSalem
How swallowing someone else's poop could save your life! Dr. Mark Davis is a Portland-based naturopath who specializes in stomach and intestinal health. He is an expert in fecal transplantation, having successfully administered it for patients of many conditions. Davis cofounded Microbiomes, LLC, which was the first group in the U.S. to offer a fecal transplant capsule, which is taken orally. He hopes that the U.S. Food and Drug Administration will eventually allow more patients to benefit from fecal transplantation.

Gut–brain axis - Video Learning - WizScience.com
The "gut–brain axis" refers to the biochemical signaling taking place between the gastrointestinal tract and the nervous system, often involving intestinal microbiota, which have been shown to play an important role in healthy brain function. The gut microbiota communicates with the Central nervous system through different pathways and influences the brain, more specifically its function and its behaviour. Several studies shows that the gut microbiota is involved in the regulation of anxiety, pain, cognition and mood. These studies used germ-free animals compared to normal animals, which were later exposed to pathogenic bacterial infections, probiotic bacteria and antibiotic drugs. The gut-brain axis is an emerging concept that could be helpful for developing new therapeutic strategies for complex CNS disorders by modifying the gut microbiota. Research suggests that the gut–brain axis, a bidirectional neurohumoral communication system in the human body, functions as a pathway for the gut microbiota to modulate brain function of its host. The postnatal microbial colonization of the gastrointestinal tract results in a long-lasting impact on the neural processing of sensory information regarding the hypothalamic-pituitary-adrenal axis stress response. Early postnatal bacterial colonization in germ free mice contribute the development of central nervous system. A recent study showed that mice whose diets were supplemented with the "Bifidobacterium breve" show elevated concentrations of fatty acids in the brain, including arachidonic acid and docosahexaenoic acid, which are known to play important roles in neurodevelopmental processes, including neurogenesis. The c-Fos activation in the paraventricular nucleus was rapidly induced by the inoculation of "Bifidobacterium infantis". Tryptophan metabolism was modulated by "Bifidobacterium infantis", suggesting that the normal gut microbiota can influence the precursor pool for serotonin, which is correlated to neurophysiological behavior. Anxiety-like behavior and central neurochemical changes were relieved in GF mice compared with specific pathogen free mice. Wiz Science™ is "the" learning channel for children and all ages.

Mixed organization of gut bacteria is revealed by microbiome imaging technology

Disruptions in the microbiome of the human gut are correlated with several diseases, including obesity and cancer. Yet little is known about the spatial organization of the nearly 1,000 bacterial species in the human gut, which can influence how the species interact with each other and with their host. In a new collaborative study, scientists from the Marine Biological Laboratory in Woods Hole, the Forsyth Institute, and Washington University in St. Louis established a simplified, model human gut microbiome in germfree mice and revealed its structure through imaging technologies developed at the MBL. The study is published this week in Proceedings of the National Academy of Sciences. We thought we would see clusters of bacteria, with some species congregating around food particles and others abundant in the mucus layer of the gut, which separates the bacteria from host tissue, says MBL scientist Jessica Mark Welch, the lead author of the study. Instead, we saw a mixed community, where each cell tended to be next to cells of a different species. The bacterial communities near the mucus layer and in the guts interior the lumen, where digested food is pushed through by muscular contractions, looked similar. The study suggests the host is mixing the microbes and preventing large clusters of single kinds of bacteria from forming, Mark Welch says. The host does this by sloughing mucus and epithelial cells into the lumen, and by mechanically mixing the contents of the gut. It may be that this mixing creates an evolutionarily stable microbial community. No one has looked at a complex microbial community in the gut this way before, says senior author Gary Borisy, a senior research investigator at the Forsyth Inst...

Fish, Pigs, Mice — and Gut Bacteria?
www.dailyrxnews.com What if you could reap the health benefits of fish oil without ever having to give up other fats? A new study from Sweden, that looked at the differences in gut bacteria of mice fed different diets, found that a diet high in fish oil produced one kind of bacteria while a diet high in lard produced a different kind. These findings raise the possibility of transplanting the gut bacteria from someone whose diet is high in fish oil into someone whose diet is high in lard to protect against weight gain and inflammation.

Life in the Lab: Working with human gut microbiota
Hilary Browne is a PhD student, working in the infection genomics group at the Wellcome Trust Sanger Institute. In this film he describes how to work safely in the lab with bacteria from the human gut including culturing them on agar plates and extracting the DNA for genome sequencing. The infection genomics programme uses a variety of different research approaches to study the biology and evolution of disease-causing organisms such as viruses, bacteria and parasites and understand how they cause disease in humans and other animals. This is one of a series of Life in the lab films providing a more in-depth insight to some of the laboratory processes used by different teams at the Wellcome Sanger Institute. The film has been developed to help support the OCR Cambridge Technical Level 3 in laboratory skills.

Meditation,  Microbiome & Gut Health - Vincent Pedre, MD
Access the show notes & MP3 Audio: http://highintensityhealth.com/drpedre Learn more about Dr. Pedre's new book, Happy Gut: http://amzn.to/1ISKJun Key Discussion Points: 02:30 Multiple Microbiomes: We have multiple different adapted microbiomes and they vary depending upon the conditions under which they live. We are learning how this microbiome interacts with us, how it creates health, and how an imbalance creates disease. 3:21 Microbiome and our Minds: In animal studies, we find that the microbiome controls how our minds work. A mouse experiment took gut bacteria from risk taker mice and placed it in anxious mice, the anxious mice took on the bolder mice characteristics. 4:17 Directed Probiotics: Dr. Pedre thinks we are heading toward having probiotics directed at specific conditions. A patient of his was in urgent care in Sweden and was prescribed an antibiotic with a prescription of a probiotic that will protect the patient from the consequences of a decimated gut microbiome. The alteration of gut bacteria from antibiotics can last anywhere from 4 months to 12 months, though mouth bacteria can normalize in a week. The medicine of the future is going to take in consideration the effect of gut bacteria. 08:07 Probiotics and Antibiotics: Dr. Pedre will often put his patient on a probiotic while they are on the antibiotic, but dosed at a different time. He might temporarily increase the dose of the antibiotic when the patient is off the antibiotic. 09:01 Resistant Antibiotics: Different antibiotics affect the microbiome differently. Clindamycin causes a 4 month shift. Cipro caused a 12 month gut microbiome shift. Cipro is commonly prescribed for UTIs and gastroenteritis. Cipro with Flagyl is a favorite of GI doctors. It was used so often on gonorrhea that gonorrhea is resistant to Cipro and an injected antibiotic must be used. Because of the heavy use of antibiotics, 2 million Americans each year develop an antibiotic resistant infections. Out of those, 23,000 people die. Among the deadliest are C. diff (clostridium difficile, which has become resistant to both Flagyl and Vancomycin, but can be resolved within 48 hours with a fecal transplant.) CRE (Carbapenem-resistant Enterobacteriaceae infection) and neisseria gonorrhoeae. Today’s medicine attacks the microbiome with no regard or respect. 16:40 Soil Microbiome: There could be a billion organisms in just one tablespoon of soil. It is the soil’s microbiome. When glyphosate is sprayed on the soil, it acts as a chelating agent to starve weeds of minerals, but also kills and alters the microbiome in the soil, which we need to bind nitrogen and make into food that the plants use. The majority of the oxygen is made from small organisms like green algae and phytoplankton in the ocean, and even cyanobacteria. 24:48 The Physical Gut and the Emotional Gut: Research has shown that gut flora impacts behavior. A probiotic supplement can help with depression, but Dr. Pedre embraces a holistic approach to treating depression, and other issues. It is not about one treatment, but how a great number of tools can work together to give optimal health.

The GUT BIOME: artificial sweeteners;Yo-Yo diets; regaining weight?
Prevmedheartrisk.com In 2015, researchers at the Weisman Institute in Israel demonstrated that saccharin, sucralose and aspartame created insulin resistance in lab mice. Antibiotic treatment and repopulation with normal bacteria cured the glucose intolerance. Other studies have shown that faecal transplants from obese humans made lab mice gain weight. In fact, gut biome or bacteria have been demonstrated to cause "yoyo" dieting effects, going back to pre-diet weights. One researcher decided to make mouse chow pellets out of breakfast cereal and pizza. Obese rats given this pizza/cereal chow did not lose weight after faecal transplant. Obese rats given regular diet did lose weight after faecal transplant. About Dr. Brewer - Ford Brewer is a physician that started as an Emergency Doctor.

Gut Bacteria and Antibiotics Part 3
- Does the gut bacteria (microbiota) change when someone does alot of drinking? - Changing your diet for one day changes your gut microbiota dramatically (previous study was done on mice) - Very sure that the gut bacteria(microbiota) changes as someone's diet changes - potential affects of diet for ulcerative colitis - certain bacteria grow well based on the food that is available to them in the gut - simple sugars, carbohydrates, white bread for example - complex carbohydrates, vegetable fibers, whole grains (harder to break down for body, and become primary food source to bacteria in intestines) - our own mucous is food for our gut bacteria!! -Les gave 3 patients antibiotics for his study, and he monitored the gut bacteria before/during/and after the patients took the antibiotics to see if there were changes. - towards the end of this video, he talks about some of the changes in gut bacteria that he noticed after the patients took the first round of antibiotics(CIPRO) - Within everyone's gut, there are many different strains of bacteria. In the study, some bacteria that were very small in population grew bigtime after taking antibiotics, and some didn't change, and some went down in population. What is quite interesting is that some of the closely related strains would show one going up in population while another closely related went down in population. http://www.ihaveuc.com/gut-bacteria-and-antibiotics-part-3/

Gut microbiota and obesity, what comes first?
Dr. Thomas Greiner explains that the gut microbiota is influenced by your genes, who you're born from and you diet. However the gut microbiota is different between obese and lean patients. In the future studies may discover a right mixture of the bacteria and prevent obesity.
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.

Gut Brain Connection for Anxiety, ADHD, Depression and Digestive Health
We discuss the gut brain connection that can be applied to stress, anxiety, ADHD, depression, mental health, and self-improvement in general. It turns that that our intestine has many nerve endings. Scientist Michael Gershon says that our gut houses a sensitive, intelligent, organ and our bodies microbiota can play a very important role in our mental health. Having these nerve cells in the intestine allows the gut to communicate with the brain. There are various scientists who describe the gut as the enteric nervous system. According to such a model, there is constant communication between the gut and brain. Beyond a discussion of prebiotics or probiotics, it turns out that the intestine is not only home to millions of neurons. but our bodies contain an ecosystem of bacteria referred to as microbiota. Dr. Stephen Collins at McMaster University is researching microbiota. He completed research with two species of mice. One species was known to be quiet and calm and the other group aggressive. By giving each group of mice microbiota from the other, researchers could influence the behavior of the other species. Providing the aggressive mice with the microbiota from the calm mice, calmed the aggressive mice down. Providing the calm mice microbiota from the aggressive mice made them more aggressive. Dr. Collins states that these findings provide evidence that microbiota influence the brain. Another interesting fact about the gut: 95% of our bodies serotonin is produced in the gut. Serotonin acts on the brain, particularly in the hypothalamus, which is a zone that manages our emotions and takes part in the regulation of our emotions. Serotonin is one of the main neurotransmitters thought to be targeted by SSRI medications for anxiety, depression and OCD. So can bacteria influence our anxiety and our ability to handle stress? Well there is some interesting information in this regard. At the Center for Neurology for Stress in Los Angeles, Kirsten Tillisch tested the effects of probiotics in yogurt. She found that the brains of healthy women ingesting probiotics over time responded better when shown stressful images. Tillisch suggests that these findings are exciting and demonstrate the potential that taking something that can be purchased from your local market could change the brain.

Q/A: Do Artificial Sweeteners Disrupt Gut Microbiome?
Firstly, I'd like to say congratulations on the weight loss. Thats an incredible amount of weight loss and I like the fact that you mentioned it because it helps highlight the importance of calories in one's diet. Moving into the question of artificial sweeteners disrupting the gut microbiome, yes they most certainly do. In fact, anything you eat does so it's no surprise that they have been found to possibly cause changes in it. Moving into the science, I want to first look at sucralose...From the Journal of Frontiers in Physiology (1), researchers wished to test the gut microbiome response to sucralose in mice. For this study, 20 male mice were used. 10 mice were feed water, and 10 mice were feed sucralose in tap water for 6 months. The concentration was 0.1 mg/ml, equivalent to the RDA in humans as being 5mg/kg/day. During different time points of the 6 month period, rRNA gene sequencing in fecal samples were taken to perform a fecal metabolic analysis. A two tailed Welches t test was used to compare the metabolites between the control and sucralose treated mice. In figure 1, 14 bacterial genera exhibited no significant difference at baseline, but were significantly different after the 6 month period. Out of the 14, 7 decreased and 5 decreased with 2 staying the same. Now these differences were just responsible for the change in their diet, which was why they then examined the gut microbiome composition associated with proinflammatory markers which was shown in figure 2. Specifically genes associated with LPS synthess significantly increased , along with elevated levels of tock shock syndrome toxin and shiga toxin which are associated with increased interluekin production. In another study published by Nature (2), researchers added saccharin, surcralose, or aspartame to the drinking water of three groups of lean 10 week old mice. They also had control groups, including mice drinking only water or mic drinking water with glucose or sucrose. They then performed glucose tolerance tests after 15,30,60,90, and 120 minute intervals. At week 11 of feeding, the three control groups had comparable glucose tolerance curves, whereas all three artificial sweetener groups had developed significant glucose intolerance. In order to see whether this was a result of gut microbiota alteration, researchers then treated the mice with antibiotics for four weeks and then repeated the experiment. What they found was that antibiotics abolished glucose intolerance in both lean and obese mice suggesting that the glucose intolerance was mediated by the gut microbiota. All in all, I think it's say to say their is some evidence around artificial sweeteners increasing the risk of glucose intolerance caused by the mediation of the gut microbiota. If you have a soda with them every now and then, no big deal...but I would be weary in saying that it's safe to consume it everyday with no long term issues developing overtime.

Antibiotic Exposure, The Microbiome and Obesity
A number of variables can cause signficant changes in the human microbiome early in life including birth method and antibiotic exposure. Understanding these shifts is important because new research suggests that shifts in the microbiome of infants could make them more prone to gain weight as adults. Participants will discuss variables involved in the development of the infant microbiome and how it affects adult metabolism and body composition in mouse models.

Diet and Gut Microbiota - mSystems
Dietary modification has long been used empirically to modify symptoms in inflammatory bowel disease, irritable bowel syndrome, and a diverse group of diseases with gastrointestinal symptoms. There is both anecdotal and scientific evidence to suggest that individuals respond quite differently to similar dietary changes, and the highly individualized nature of the gut microbiota makes it a prime candidate for these differences. To overcome the typical confounding factors of human dietary interventions, here we employ ex-germfree mice colonized by microbiotas of three different humans to test how different microbiotas respond to a defined change in carbohydrate content of diet by measuring changes in microbiota composition and function using marker gene-based next-generation sequencing and metabolomics. Our findings suggest that the same diet has very different effects on each microbiota’s membership and function, which may in turn explain interindividual differences in response to a dietary ingredient.

Microbes in the Gut Determine the Risk for Cancer
An article published in the journal of the American Society for Microbiology called mBio showed that both inflammation and a certain microbiome contribute to the development of colon cancer in mice. Researchers transferred a stool sample from mice with colon cancer to germ-free mice and found that the incidence of colon cancer double that when compared to normal mice. They also found that giving antibiotics to these mice before and after the stool transplantation significantly reduced the incidence of colon cancer. The researchers also determined that there were specific bacteria that were associated with the increased incidence of colon cancer. The conclusion of the study was that both inflammation and the stool microflora were necessary to increase the incidence of colon cancer. For more information, please visit www.doctorsaputo.com

Food for Good Gut Bacteria w/ Drs Justin & Erica Sonnenburg
Episode #81: Drs  Justin and Erica Sonnenburg are two top microbial scientists at Stanford University and author of The Good Gut. In this interview these two pioneers share diet tips from their work at Stanford that can help you increase the diversity of the trillions of bacterial organisms in your gut, boost your metabolism and reduce inflammation. The Good Gut Book: http://amzn.to/1SYkEeB Read the Interview Show Notes: http://highintensityhealth.com/justin-erica-sonnenburg-top-foods-to-fuel-healthy-gut-bacteria/ --------------------------------------Lets Connect---------------------------------- ➢ Facebook https://www.facebook.com/MikeMutzelMS ➢ Listen to the Audio in iTunes: http://highintensityhealth.com/itunes ➢ Instagram https://www.instagram.com/metabolic_mike --------------------------------------Key Takeaways--------------------------------- 2:29 The Power of Microbes: Over the past decade there has been an awakening about the gut, microbiome and genetics. Microbes connect in major ways to human biology with digestion, metabolism, systemic immune function and central nervous system. There is no part of our body that is not touched, directly or indirectly, by these microbes in some way. 4:32 Microbial Digestion: Gut microbes rely upon complex carbohydrates (dietary fiber) to complete their functions in the gut. They digest our resistant complex polysaccharides that come from plant material; fruits, vegetables, legumes, and whole grains. At the same time, they release compounds into our gut that are soaked into our bloodstream that do things like help maintain our immune system balance and help us decide whether we are storing calories or burning them. 5:56 Feed Your Microbes: High fiber foods feed your microbes. The Sonnenburgs make sure that their family consumes high fiber foods at every meal. 7:30 Microbial Diversity – The Jelly Bean Analogy: Think of each species of gut bacteria as a color of jelly bean. The Western diet will be a simple mix of a few colors. Modern day hunter gatherers or those who live similarly to those at the beginning of agriculture, have many more colors of jelly beans. They have species of gut bacteria that are not seen in the Western world. In the environment, if an ecosystem loses its diversity, it’s a bad thing. Potentially, that is the case with our microbial ecosystem? 9:25 A Skewed Perspective of Microbes: Research has primarily focused on Westerners, but now research is looking into populations around the globe. The NIH Human Microbiome Project spent years working to determine what a healthy microbiota is and working to determine how the microbiome changes in different disease states. 10:20 Microbiota, a Key Player in Disease: Just because someone is healthy, doesn’t mean they have a healthy microbiota. Evidence is building that shows that most Americans have unhealthy gut microbiota, which predisposes us to many Western diseases. Metabolic syndrome, heart disaease, autoimmune diseases, cancers, and the like, are all become more prevalent. It is possible that there are individual causes for these diseases, but more likely, that there are only a few causes and that gut microbiota is central of them. 11:54 Traditional Societies: Humans have spent 95% of our time on the earth as hunter gatherers. By looking at hunter gatherer societies today, we can get a better understanding of what our gut microbiota is supposed to be. 13:39 The High MAC Diet: Microbiota Accessible Carbohydrates are dietary fiber that we consume to feed our microbiota. Tubers eaten by hunter gatherers have not been modified by agriculture, making it texturally and nutritionally different from what we eat. Since we cannot recreate the diet of hunter gatherers, we can eat lots of different foods, including tubers, along with berries and leafy greens and increase fiber to diversify and sustain our microbiota. 15:56 Polyphenols: When researching the impact of plant fiber, it is challenging for researchers to parse out the other benefits of the consumption of plants. In general, Westerners should eat more plants that contain complex dietary fibers, not only to feed their microbiota, but to garner the other benefits. 18:01 Fiber Consumption Comparison: Hunter gatherers consume about 150 – 200 grams per day of dietary fiber. In the U.S., we struggle to eat 15 grams per day. If you starve the microbes in the gut, they begin to consume the mucus lining of your digestive tract. 19:32 Short Chain Fatty Acids Created By Our Microbiota: Acetate, propionate, and butyrate are the major ones. In mice, propionate has been shown to be a regulator of metabolism. Butyrate and propionate have shown in mice to be a regulator of inflammation. They may also play a role in satiety. One day we will have enough information to match our foods to specific microbes in our gut. Increase dietary fiber, to increase short chain fatty acids.
