Short-term antibiotic use linked to long-lasting resistance in gut bacteria

Short-term antibiotic use linked to long-lasting resistance in gut bacteria

Stanford University researchers report that ciprofloxacin use drives persistent antibiotic resistance in human gut bacteria, with resistance emerging independently across diverse species and enduring for over 10 weeks.

Even short-term antibiotic use may cause resistance in gut bacteria

New Delhi, April 26: As antimicrobial resistance (AMR) has become a global health concern, with millions of deaths occurring each year due to it, a new study showed how even a short period of antibiotic use can lead to persistent resistance in human gut bacteria. Researchers from the Stanford University in the US focused their study on ciprofloxacin — used to treat bacterial infections in many different parts of the body. They showed that ciprof…

Brief antibiotic use drives human gut bacteria towards low-cost resistance - AMR Insights

A study involving 60 human participants exposed to ciprofloxacin found that brief exposure drives the evolution of antimicrobial resistance in gut commensals. The study found that gyrase mutations arose de novo within the participants and exhibited no measurable fitness cost. The findings highlight the human gut’s capacity to promote resistance evolution and identify key genomic and ecological factors that shape bacterial adaptation in vivo. Thi…
