Gut microbiota compositions in the carriers and noncarriers of third-generation cephalosporin–resistant Escherichia coli: A study among children in southern Taiwan

Antimicrobial resistance, particularly in third-generation cephalosporin-resistant (3GC-R) Escherichia coli (E. coli), poses major global health challenges and has various clinical implications. Researchers have explored the relationship between extended-spectrum β-lactamase-producing E. coli and gut microbiota composition, which influence host health and disease susceptibility, in adults. In this study, we analyzed gut microbiota composition in Taiwanese children by the colonization status of 3GC-R E. coli.
