Frozen bacteria kept for 5,000 years in an underground cave have been found to be resistant to modern antibiotics, researchers say. In the depths of Scărișoara Cave, one of Romania’s largest ice caves, preserved under a 5,000-year-old layer of ice, scientists discovered a strain of Psychrobacter SC65A.3 – bacteria resistant to modern antibiotics.
Bacteria can survive for thousands of years under extreme conditions: under ancient layers of ice, in permafrost, under the sea, or in glacial lakes.
