Research Article | Host-Microbe BiologyDistinct Gut Microbiota Induced by Different Fat-to-Sugar-Ratio High-Energy Diets Share Similar Pro-obesity Genetic and Metabolite Profiles in Prediabetic MiceVarious types of diet can lead to type 2 diabetes. The gut microbiota in type 2 diabetic patients are also different. So, two questions arise: whether there are any commonalities between gut microbiota induced by different pro-obese diets and whether these commonalities lead to disease. Here we found that high-energy diets with two different fat-to-sugar ratios can both cause obesity and prediabetes but enrich different gut microbiota....
Research Article | Novel Systems Biology TechniquesPseudomonas aeruginosa Alters Its Transcriptome Related to Carbon Metabolism and Virulence as a Possible Survival Strategy in Blood from Trauma PatientsWhile a considerable body of knowledge regarding sepsis in trauma patients is available, the potential influence of trauma-induced changes in the blood of these patients on the pathogenesis of Pseudomonas aeruginosa is basically an unexplored area. Rather than using standard laboratory media, we grew P....
Research Article | Host-Microbe BiologyAlterations in Gut Glutamate Metabolism Associated with Changes in Gut Microbiota Composition in Children with Autism Spectrum DisorderMultiple lines of evidence suggest that the gut microbiota may play an important role in the pathogenesis of ASD, but the specific mechanism is still unclear. Through a comprehensive gut metagenomic and metabolome study of children with ASD, alterations in gut metabolite composition were found in children with ASD, and these alterations were linked to changes in gut microbiota composition. This may give us a deeper understanding of the...
Research Article | Host-Microbe BiologyButyrate Producers as Potential Next-Generation Probiotics: Safety Assessment of the Administration of Butyricicoccus pullicaecorum to Healthy VolunteersThis study is the first to determine the safety and tolerance in humans of a butyrate-producing Clostridium cluster IV next-generation probiotic. Advances in gut microbiota research have triggered interest in developing colon butyrate producers as next-generation probiotics. Butyricicoccus pullicaecorum...
Commentary | Host-Microbe BiologyCrowdsourcing Our National GutThe microbes of the human intestinal tract play a profound role in our health. The complex interactions between our gut microbial communities and the external environment, and the resulting functional consequences, can be difficult to disentangle.
Special Issue Perspective | Host-Microbe BiologyCan Diet Influence Our Health by Altering Intestinal Microbiota-Derived Fecal Metabolites?The human gastrointestinal tract harbors a diverse, highly mutualistic microbial flora which could produce a myriad of specialized metabolites. These specialized metabolites are the chemical cellphones that gut microflora use to communicate with their human host and could potentially be used to cure diseases.
Special Issue Perspective | Host-Microbe BiologyRole of the Gut Microbiome in Vertebrate EvolutionDarwin referred to life as a struggle. Organisms compete for limited resources in nature, and their traits influence the outcome.
Special Issue Perspective | Therapeutics and PreventionBeyond Structure: Defining the Function of the Gut Using Omic Approaches for Rational Design of Personalized TherapeuticsOver the past 10 years, microbiome research has focused on defining the structures associated with different disease states in multiple systems, but has fallen short on showing causation. Prior omic studies have generated many new hypotheses, but moving forward we need to start dissecting the function of each bacterium alone and in concert with complex bacterial communities in well-characterized systems.
Editor's Pick Research Article | Host-Microbe BiologyMulti-omics Analysis of Periodontal Pocket Microbial Communities Pre- and PosttreatmentPeriodontal disease affects the majority of adults worldwide and has been linked to numerous systemic diseases. Despite decades of research, the reasons for the substantial differences among periodontitis patients in disease incidence, progressivity, and response to treatment remain poorly understood. While deep sequencing of oral bacterial communities has greatly expanded our comprehension of the microbial diversity of periodontal...
Editor's Pick Research Article | Host-Microbe BiologyIntegrated Role of Bifidobacterium animalis subsp. lactis Supplementation in Gut Microbiota, Immunity, and Metabolism of Infant Rhesus MonkeysProbiotics are becoming increasingly popular due to their perceived effects on health, despite a lack of mechanistic information on how they impart these benefits. Infant formula and complementary foods are common targets for supplementation with probiotics. However, different probiotic strains have different properties, and there is a lack of data on long-term health effects on the consumer. Given the increasing interest in...
