In this Nature Medicine news article, Roxanne Khamsi reports on research around the world showing the microbiome exerts an influence on the human immune system. If scientists knew how to control the key process of inflammation, they could profoundly influence the course of disorders such as inflammatory bowel disease, heart disease, and liver disease. Khamsi covers several possibilities on how…

For Catherine Lozupone, formerly a researcher in the Knight and Gordon labs and now faculty at the University of Colorado, characterizing a 'healthy microbiota' or even a 'healthy diet' is far from straightforward. At Experimental Biology 2015 in March, Lozupone presented her research and brought forward a provocative idea: a healthy microbiota is one that matches your diet. She spoke…

Prebiotics and probiotics are food components that directly target the gut microbiota. This recent human study investigated their effects on gut microbiota and metabolic risk markers in obesity. In this trial, researchers tested the probiotic Lactobacillus paracasei, which has been associated with a healthy metabolic profile in previous research. They also tested flaxseed -- composed of 30% dietary fibres, including…

Scientists aren't clear on the exact relationship between the Firmicutes to Bacteroides/Prevotella (F:B) ratio, fecal short-chain fatty acid (SCFA) levels, and obesity. This observational human study analyzed 3-day dietary intakes, physical activity levels, body mass index, fecal microbiota, and SCFAs in both lean and overweight/obese research participants (n=94).   They found that diet and physical activity levels were similar between…

Do specific microbiota determine levels of specific metabolites? How does the metabolite profile develop during establishment of the microbiome in infants? Can we assess an individual’s physiological state based on gut flora and metabolites? These questions are key to translating scientific findings related to intestinal metabolites in order to bring them to the clinic. The relatively new scientific field of…

Microglia are important immune system cells in the brain that can destroy target cells. They are important for proper brain development and associated with neuropsychiatric or neurological disorders in humans. A team of researchers set out to address this question: what controls microglia maturation and function under normal conditions? They found that host microbiota contributed substantially to microglia homeostasis. Germ-free…

This interesting and well-balanced review examined how long-term and short-term changes in dietary fibre intake affect the microbiome and metabolome. Greater microbial diversity is associated with long-term diets high in fruit/legume fibre, while beneficial Firmicutes decrease in diets high in fat/sugar and low in fibre. Short-term diets based exclusively on animal products and those high in protein and low in…

Bacteria in food, including probiotics, are a major environmental source of microbes in the human body. But what happens to the bacteria once they are ingested? Do they have any short- or long-term effects on the body?

When treating vulnerable populations with probiotics in research and clinical practice, the quality of probiotic products is important because the stakes are high. In October, 2014, for example, a preterm infant in Connecticut died of gastrointestinal mucormycosis that was caused by a contaminated probiotic product given in hospital. What lessons can clinicians and researchers take away from this situation?  …

Dr. Sanders served as the founding president of the International Scientific Association for Probiotics and Prebiotics (ISAPP) and is currently the organization’s Director of Scientific Affairs/ Executive Officer. This international, non-profit association of academic and industrial scientists is dedicated to advancing the science of probiotics and prebiotics (www.isapp.net). Through numerous written, oral and video pieces, including a website, www.usprobiotics.org, she strives to provide objective, evidence-based information on probiotics for consumers and professionals. Key activities include: Panels to determine GRAS status of probiotic strains ; member of the American Gastroenterological Association Scientific Advisory Board for AGA Center for Gut Microbiome Research and Education ; World Gastroenterology Organisation Committee preparing practice guidelines for the use of probiotics and prebiotics for GI indications (2008, 2011, 2014) ; working group convened by the FAO/WHO that developed guidelines for probiotics (2002).

Elena Verdú
Dr. Verdu’s research has focused on the pathophysiology of inflammatory and functional gastrointestinal disorders. She undertook clinical research training at the University of Lausanne, Switzerland, where she studied the interaction between chronic infection with Helicobacter pylori and gastritis in humans and the possible therapeutic role of probiotic bacteria. Her PhD studies in the Institute of Microbiology and Gnotobiology at the Czech Academy of Science and University of Lausanne focused on the effect of bacterial antigens in animal models of inflammatory bowel disease. As a post-doctoral fellow at McMaster University she gained experience with animal models of gut functional diseases and investigated the mechanisms of action of probiotic bacteria. As a member of the Farncombe Family Digestive Health Research Institute at McMaster University, Dr. Verdu investigates host-microbial and dietary interactions in the context of celiac disease, irritable bowel syndrome and inflammatory bowel disease. She has been honored with the New Investigator Award (Canadian Celiac Association), the New Investigator Award (Functional Gut-Brain Research Group, USA) and the Campbell Research Award in celiac disease (Canadian Celiac Association). The American Gastroenterology Association and the Canadian Association of Gastroenterology have awarded her the “Master’s in Gastroenterology Award” for basic science and “Young Investigator’s Award”, respectively. She is Associate Professor at the Division of Gastroenterology, Dep. of Medicine at McMaster University and currently directs the Axenic Gnotobiotic Unit at McMaster.
