Dietary florfenicol residues from eggs drive multidrug resistance in Salmonella and enrich intestinal antibiotic resistance genes
This study comprehensively investigates the molecular and ecological mechanisms by which florfenicol (FFC) residues drive multidrug resistance (MDR) in Salmonella and the intestinal microbiota. By integrating long-term in vitro induction with an in vivo mouse model of dietary exposure, we evaluated the risk of resi...
