This study investigates microbial dysbiosis in children with cystic fibrosis, identifying glycerol as a driver of altered microbial competition and linking colibactin production to increased colorectal cancer risk.

This study examines how Bacteroides colonization affects gut and systemic health in mice, revealing sex-dependent immune responses and macrophage marker changes in specific gut regions.

This study uses culturomics to analyze gut microbiota in CF and non-CF individuals, finding higher bacterial loads and spatially specific dysbiosis in CF mucosal samples.

This study profiles bile acids in stool from children with and without cystic fibrosis, revealing differences in BA species and microbial metabolism, and highlights the ferret model's suitability for BA research in CF.
