Scientists Flip a Gut Virus “Kill Switch” – And Expose a Hidden Threat in Antibiotic Treatment

Scientists have long known that bacteriophages, viruses that infect bacteria, live in our gut, but exactly what they do has remained elusive. Researchers developed a clever mouse model that can temporarily eliminate these phages without harming the bacteria, using a UTI treatment ingredient called acriflavine. Their experiments showed that without phages, gut bacteria become less [...]
