This study shows that commensal bacteria in reused chicken litter reduce horizontal gene transfer of antimicrobial resistance plasmids to Salmonella.

This study shows that antibiotic-resistant Salmonella can acquire resistance from gut commensals in antibiotic-free broiler chicks, driven by horizontal gene transfer and acidic selection pressure, suggesting antibiotic reduction alone may not limit resistance spread.

This study shows that plasmids and hotspot mutations enhance the survival of S. Heidelberg in poultry litter by increasing fitness and antibiotic resistance.
