Over two and a half years, researchers at the University of Nottingham analysed microbiomes from chickens, carcasses and environments. The resulting network of correlations between livestock, environments, microbial communities and antimicrobial resistance suggests multiple routes for improving antimicrobial resistance surveillance in livestock production.
The use of antimicrobials used to prevent and treat infections in livestock production on farms is associated with the rise of antimicrobial resistant (AMR) infections.
The study, published in Nature Food, identified several antimicrobial resistant genes (ARGs) that were shared between chickens and the farms they lived on that are potentially highly transmissible.
The findings also show that a core subset of the chicken gut microbiome, featuring clinically relevant bacteria and antibiotic resistance genes correlates with AMR profiles of E. coli, colonizing the gut.

How does excess sugar affect the developing brain throughout childhood and adolescence
Parents often stress about their kids' sugar intake, but it can be hard to know how much is too much or what to do about it.
Scientists Have Grown Diamonds in Just 150 Minutes
Natural diamonds take billions of years to form in the extreme pressures and temperatures deep underground. Synthetic forms can be produced far quicker, but they typically still require some intense squishing for up to several weeks.
