This study shows that IncI1-blaCTX-M-1 plasmids transfer efficiently between chicken and human E. coli but are less stable in human hosts, limiting their spread.

The paper investigates whether flumequine selects for the same resistance mechanisms in E. coli as enrofloxacin, finding similar SNPs in gyrA and comparable resistance rates.

The paper determines the minimal selective concentrations of three antibiotics in broiler cecal fermentations to identify thresholds for antimicrobial resistance selection.

This study shows that persistent antimicrobials in broilers lead to prolonged antimicrobial resistance, while non-persistent ones have shorter effects.
