Zebrafish microbiome studies make waves

This Review discusses the strengths of the zebrafish model for microbiome research, and highlights important insights gleaned from observational and manipulative microbiome studies in zebrafish. Zebrafish have a 50-year history as a model organism for studying vertebrate developmental biology and more recently have emerged as a powerful model system for studying vertebrate microbiome assembly, dynamics and function. In this Review, we discuss the strengths of the zebrafish model for both observational and manipulative microbiome studies, and we highlight some of the important insights gleaned from zebrafish gut microbiome research.
