Antibiotic overuse perpetuates “infectious-disease nightmare,” study reveals: Drug resistance in gut microbes persists years after single course
Even short-term antibiotic use permanently alters gut microbiomes, fostering antibiotic-resistant bacteria that persist for years. Countries with high antibiotic sales harbor populations with significantly more drug-resistant gut microbes, even in non-users. Early-life antibiotic exposure reduces gut biodiversity irreversibly, destabilizing microbiome networks for life. Bacteria evolve resistance without losing fitness, making them a persistent global health … Leer más
