Join us on Wednesday February 24th at 10AM PST to learn how Breanna Metras, from the Swanson lab at the University of Illinois at Urbana-Champaign in the Division of Nutrition Sciences used both traditional plating methods and long-read microbiome sequencing to determine whether the microbial profiles and CFU/g density claims of multiple well-known human and pet commercial kefir products are accurate.
Breanna Metras is a USDA Graduate Research Fellow in Dr. Kelly Swanson's lab in the division of Nutritional Sciences at the University of Illinois, Urbana-Champaign.
The Swanson Laboratory uses genomic biology to study nutrition-related problems in the areas of obesity and gastrointestinal health. Both comparative and applied nutrition research projects are performed in our laboratory, including those studying human subjects, companion animals (e.g., dogs and cats), and traditional animal models (e.g., rodents and pigs). A primary aim of our laboratory is to study the effects of diet and age on gastrointestinal microbiota community composition and activity. DNA-based techniques [e.g., quantitative polymerase chain reaction (qPCR); next-generation sequencing] are used in our lab. Current projects are designed to evaluate the effects of dietary fibers and prebiotics, dietary lipids, protein: carbohydrate ratio, and changes in endocrine function on gastrointestinal microbial populations. Key relationships between intestinal microbiota, host physiology (e.g., metabolite profiles; tissue histology), and disease are also being studied.
