Long before the advent of antibiotics, bacteria had already begun to develop remarkable resistance strategies. In an exciting discovery, researchers have uncovered a bacterial strain known as Psychrobacter, found in 5,000-year-old ice layers within a cave, showcasing resistance to ten modern antibiotics. This ancient microorganism not only demonstrates resistance but also possesses promising enzymatic activities, enabling it to inhibit the growth of ‘superbugs,’ which are resistant to multiple antibiotics. Additionally, the genetics of this strain offers valuable insights into the evolutionary origins of antibiotic resistance. Bacteria have shown an incredible ability to adapt to Earth’s most extreme environments, from scorching … Read more
