SP34 - Biodiversité et évolution
Diversity and evolution of mobile genetic elements and their interactions
Mobile genetic elements are ubiquitous drivers of microbial evolution. Recent discoveries have revealed an unexpected diversity beyond classical phages and plasmids, including phage-plasmids, satellites, and other hybrid elements. This session will explore how we identify and classify these entities, and how their interactions in cellulo shape genomes and microbial communities.

SP35 - Modelisation / IA
Integrating AI and models to elucidate infectious and microbial dynamics
This session aims to bring together researchers at the interface of biology and quantitative sciences to explore how modeling and artificial intelligence advance our understanding of infectious and microbial systems. It welcomes contributions from virology, immunology, microbiology, mathematics, and systems biology, addressing the dynamics of pathogens and microbial communities across scales, from within-host processes to population-level epidemics, with a particular focus on the integration of data, mechanistic models, and artificial intelligence and machine learning methods.

SP37 - Microbiologie des aliments
Interactions au sein des communautés microbiennes: y'a de l'action !
Cette session s’ouvre à des travaux portant sur les écosystèmes microbiens alimentaires et sur les interactions biotiques entre espèces, qui jouent un rôle clé dans leurs assemblages. Les micro-organismes interagissent constamment et co-évoluent au sein de leur environnement contribuant ainsi à l’assemblage de ces communautés microbiennes. Dans ce contexte, il est d’intérêt de mieux comprendre comment ces microorganismes interagissent ainqi que leurs rôles et leurs impacts positifs.

SP39 - Environnement
Microbial dynamics in urban ecosystems
Urban environments represent rapidly expanding ecosystems where microorganisms play essential yet underexplored ecological and functional roles. This session aims to bring together researchers investigating microbial ecology, diversity, dynamics and functions across urban habitats, from built environments to urban waters and atmosphere. By integrating ecological, environmental and health perspectives, the session will highlight how microorganisms contribute to urban ecosystem functioning, adaptation, resistance and/or resilience in the Anthropocene era.
