Therapeutics and Prevention
Special Issue Perspective | Therapeutics and PreventionMoving Microbiome Science from the Bench to the Bedside: a Physician-Scientist PerspectiveThe recognition over the past decade that nearly all diseases are associated with changes in the microbiome has raised hope that microbiome-based therapeutics may cure many human ailments. Billions of dollars are being poured into microbiome-oriented biotech companies, and the coming years will undoubtedly witness the approval of the first generation of these products.
Special Issue Perspective | Therapeutics and PreventionRigorous Statistical Methods for Rigorous Microbiome ScienceHigh-throughput sequencing has facilitated discovery in microbiome science, but distinguishing true discoveries from spurious signals can be challenging. The Statistical Diversity Lab develops rigorous statistical methods and statistical software for the analysis of microbiome and biodiversity data.
Research Article | Therapeutics and PreventionInfluence of the Intestinal Microbiota on Colonization Resistance to Salmonella and the Shedding Pattern of Naturally Exposed PigsSalmonella is a global threat for public health, and pork is one of the main sources of human salmonellosis. However, the complex epidemiology of the infection limits current control strategies aimed at reducing the prevalence of this infection in pigs. The present study analyzes for the first time the impact of the gut microbiota in Salmonella infection in pigs and its shedding pattern in naturally infected growing...
Research Article | Therapeutics and PreventionHelminth-Based Product and the Microbiome of Mice with LupusRecently, several papers referred to the association of different bacteria with lupus in mice and humans. This is the first report to demonstrate the effect of a compound derived from helminths on the induction of remission in mice with lupus and its association with a bacterial change. We show that several genera, including Akkermansia, are associated with clinical and serological parameters of lupus, while other genera,...
Research Article | Therapeutics and PreventionComparative Metabolomics and Transcriptomics Reveal Multiple Pathways Associated with Polymyxin Killing in Pseudomonas aeruginosaPseudomonas aeruginosa has been highlighted by the recent WHO Global Priority Pathogen List due to multidrug resistance. Without new antibiotics, polymyxins remain a last-line therapeutic option for this difficult-to-treat pathogen. The emergence of polymyxin resistance highlights the growing threat to our already very limited antibiotic armamentarium and the urgency...
Research Article | Therapeutics and PreventionBacteriophages Synergize with the Gut Microbial Community To Combat SalmonellaAntibiotic-resistant bacteria are a global threat. Therefore, alternative approaches for combatting bacteria, especially antibiotic-resistant bacteria, are urgently needed. Using a human gut microbiota model, we demonstrate that bacteriophages (phages) are able to substantially decrease pathogenic Salmonella without perturbing the microbiota. Conversely, antibiotic treatment leads to the eradication of close to all commensal...
Research Article | Therapeutics and PreventionCombinatorial Approaches to Viral AttenuationLive viral vaccines rely on attenuated viruses that can successfully infect their host but have reduced fitness or virulence. Such attenuated viruses were originally developed through trial and error, typically by adaptation of the wild-type virus to novel conditions. That method was haphazard, with no way of controlling the degree of attenuation or the number of attenuating mutations or preventing evolutionary reversion. Synthetic...
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.
