Distinct Genetic and Functional Traits of Human Intestinal Prevotella copri Strains Are Associated with Different Habitual Diets (Cell Host & Microbe)

The gut microbiome includes several strains per species, with high genomic diversity. By examining Italian subjects with varying dietary habits, De Filippis et al. demonstrate that diet may select distinctive Prevotella copri strains with distinguishable functions. This diversity may explain subject-specific responses to dietary interventions and variations in human health.
