A genomic study of gut microbes during antibiotic use finds selective sweeps in a DNA gyrase gene that drive resistance.

Antibiotic resistance genes were typically isolated by cloning from cultured bacteria or by PCR amplification. Those methods missed potential antibiotic resistance reservoirs because of ...

2 They recently reported in Cell Host & Microbe that tolerance comes from mutations in genes related to nutrient production while persistent bacteria activate a specific DNA repair pathway to survive.

A research team has developed a computational tool, Argo, designed to accurately track ARGs in environmental samples, providing insights into their dissemination and associated risks.
