Integrating microbiomes into One Health: insights from the 2025 One Health World Microbiome Partnership Summit

Research across multiple disciplines is showing that microbial communities are crucial for many facets of health and resilience, from human, plant, and animal health to disease resistance, ecosystem adaptability, and planetary climate regulation. Recognising this importance, the World Microbiome Partnership (WMP) was launched to integrate microbiome science into global health, agricultural, environmental, and regulatory systems.1 The One Health World Microbiome Partnership Summit, convened on June 20, 2025, under the High Patronage of French President Emmanuel Macron, brought together more than 40 leading microbiome experts and stakeholders from all sectors representing 16 countries and including a large online audience, with the goal of catalysing a coordinated, cross-sectoral microbiome research and innovation agenda aligned with One Health principles.
