Special Issue Perspective | Host-Microbe BiologyConsidering the Other Half of the Gut Microbiome: BacteriophagesBacteriophages, viruses specific to bacteria, regulate bacterial communities in all known microbial systems. My research aims to determine how they interact with the trillions of bacteria found in the human gut.
Research Article | Host-Microbe BiologyTemperate Bacteriophages from Chronic Pseudomonas aeruginosa Lung Infections Show Disease-Specific Changes in Host Range and Modulate Antimicrobial SusceptibilityPseudomonas aeruginosa is a key opportunistic respiratory pathogen in patients with cystic fibrosis and non-cystic fibrosis bronchiectasis. The genomes of these pathogens are enriched with mobile genetic elements including diverse temperate phages. While the temperate phages of the Liverpool epidemic strain have been shown to be active in the human lung and enhance...
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...
Research Article | Host-Microbe BiologyA Prospective Metagenomic and Metabolomic Analysis of the Impact of Exercise and/or Whey Protein Supplementation on the Gut Microbiome of Sedentary AdultsThe gut microbiota of humans is a critical component of functional development and subsequent health. It is important to understand the lifestyle and dietary factors that affect the gut microbiome and what impact these factors may have. Animal studies suggest that exercise can directly affect the gut microbiota, and elite athletes demonstrate unique beneficial and diverse gut microbiome characteristics. These characteristics are...
Editor's Pick Research Article | Host-Microbe BiologyLocal Action with Global Impact: Highly Similar Infection Patterns of Human Viruses and BacteriophagesWhile host-virus interaction interfaces have been previously investigated, relatively little is known about the indirect interactions of pathogen and host proteins required for viral infection and host cell function. Therefore, we investigated the topological relationships of human and bacterial viruses and how they interact with their hosts. We focused on those host proteins that are directly targeted by viruses, those that are...
