Metabolic modeling of microbial communities in the chicken ceca reveals a landscape of competition and co-operation

This work demonstrates the potential of using the chicken cecal microbiome as a model system for investigating the complex metabolic interactions and key contributions that drive community dynamics in the gut. Our model-based predictions offer insights into how keystone taxa like B. fragilis may shape the metabolic landscape and functional organization of microbial communities. The observed metabolic adaptations in the absence of B. fragilis share metabolic similarities with profiles seen in dysbiotic states in humans and underscore the translational relevance of these insights for understanding gut health across different host systems.
