Purina Institute drives the dialogue on the microbiome

The Purina Institute is leading the debate on microbiome research in veterinary medicine by helping to translate cutting-edge research into evidence-based knowledge. Through scientific dialogue on the microbiome and its practical implications, the Purina Institute highlights the vital role the microbiome plays in pet health – specifically in two key areas: the gut-brain axis and the responsible use of antibiotics.

The research sheds light on how the gut microbiome influences brain function, behaviour and disease via precisely defined biological pathways. The Purina Institute Microbiome Forum in November 2025 brought together leading scientists and veterinary experts from around the world, who presented new findings demonstrating that the gut-brain axis operates via various mechanisms, including microbial metabolites, immune signals and neural pathways.
