In the ice masses of the Scărișoara Cave, located in the Romanian Carpathians, scientists have discovered a unique bacterium that has been frozen for approximately 5000 years. The identified organism demonstrates resistance to ten different modern antibiotics from eight classes, raising concerns among researchers.

Characteristics of the Ancient Microorganism
The ice in this cave formed during the last glacial maximum, around 13,000 years ago, and in some areas, its thickness reaches 20 meters. It is in these locations that biologists found the strain Psychrobacter cryohalolentis — a microorganism capable of surviving in low temperatures and high salinity. This type of bacteria is potentially dangerous to humans and can cause infections of the inner linings of the heart and abdominal wall.
Genetic Resistance and Discovery Potential
A detailed analysis of the bacterium’s DNA revealed over 100 genes responsible for antibiotic resistance. Specifically, this microorganism does not respond to medications used to treat skin infections, urinary tract infections, and even tuberculosis. This indicates that the mechanisms of antibiotic resistance arose long before the advent of modern medical drugs.
“The ancient microorganism is capable of inhibiting the growth of other bacteria, including Pseudomonas aeruginosa, Klebsiella pneumoniae, and Staphylococcus aureus — common causes of nosocomial infections. If scientists manage to isolate antimicrobial polypeptides from it, this could pave the way for the development of new agents against modern ‘superbacteria’.”
Researchers also emphasize the potential benefits of this discovery: the isolated microorganism may suppress the development of other bacteria that often cause nosocomial infections. If scientists succeed in isolating specific antimicrobial compounds from it, this could form the basis for the development of new drugs against antibiotic-resistant pathogens.
At the same time, researchers warn: due to melting glaciers, similar microorganisms have a chance of entering the environment. Such discoveries are not only scientific sensations but also reminders of the potential risks associated with climate change.
