SP28 - Pathogénie microbienne

Inherited heterogeneity in pathogenic bacteria

Inherited heterogeneity in pathogenic bacteria is crucial for their survival and ability to cause infection, as it allows them to adapt to fluctuating environments and evade the host immune system, with strategies such as immune evasion through surface structure alterations, division of labor among cells for different functions like growth or biofilm formation, bet-hedging to ensure some cells survive under stress, and the ability to colonize different surfaces in the host, all of which contribute to their persistence and pathogenicity, and these mechanisms of phenotypic inheritance include phase variation through DNA inversion, DNA methylation to regulate virulence gene expression, and positive feedback loops that reinforce the stable expression of certain traits, ensuring bacterial populations can thrive under selective pressures and maintain infection over time.

SP29 - Virologie clinique

Epidémies mondiales et nationales : quand les agents infectieux sont toujours bien présents !

Descriptif à venir.

SP30 - Microbiologie clinique

"Nouveaux" outils pour le diagnostic et interprétation des données

Cette session s'intéresse à toutes les applications diagnostiques, de résistance, épidémiologiques, d'identification de pathogènes, de compréhension des infections utilisant les approches NGS et notamment amplicons-NGS.

SP31 - Microbiologie des aliments

Food microorganisms: resistant or tolerant?

This session is open to all studies related to the effect of antimicrobials (antibiotics, biocides, etc.) on food microorganisms, as well as their use in food production.

SP32 - Antimicrobiens

New antimicrobial strategies

It is well established that bacteria can develop resistance to antibiotics, which represents a major and growing public health concern. A key policy to reverse this trend is to restrict the indiscriminate use of antibiotics. However, the emergence of resistant microbes is inevitable. Therefore, it is essential to continually develop new strategies and antimicrobial compounds. The purpose of this session is to present some ongoing efforts to identify potential new strategies. It will also highlight the molecular aspects of the promising cellular processes that could be targeted.

SP33 - Environnement

One health

The "One Health" session of Environmental Microbiology aims to address all aspects linking microorganisms to human, animal, and environmental health. This includes mechanisms shared across all living systems that facilitate the transfer of microorganisms, for example, from humans to animals in the case of zoonoses. It also includes those that, conversely, enable comprehensive control over microorganisms, such as innate immunity.
