A 5,000-year-old bacterium from Romania’s ice cave resists modern antibiotics due to natural evolution, offering potential for new treatments but raising concerns about melting glaciers spreading resistance.
A 5,000-year-old bacterium, Psychrobacter SC65A.3, discovered in Romania’s Scarisoara Ice Cave, exhibits resistance to at least 10 modern antibiotics despite never being exposed to human-made drugs.
Found in a 25-meter ice core, the microbe carries over 100 antimicrobial resistance genes and can inhibit dangerous pathogens like Staphylococcus aureus and E. coli.
Researchers believe resistance evolved naturally through ancient microbial warfare, not human antibiotic use.
The bacterium produces compounds with potential to treat drug-resistant infections, offering hope for new antibiotics.
However, melting glaciers could release such microbes and their genes into modern ecosystems, potentially worsening the global antibiotic resistance crisis.
