Frozen for 5,000 years, this ice cave bacterium resists modern antibiotics
A 5,000-year-old Psychrobacter strain recovered from Romanian cave ice harbors over 100 antibiotic-resistance genes and shows resistance to drugs used to treat tuberculosis and urinary tract infections, per a Frontiers in Microbiology genome and functional profiling study.
Why it mattersPsychrobacter from Romanian ice cave with over 100 resistance genes forces antibiotic developers to expand screening protocols.
