HCR Update from Mark Sanna: The results of an analysis performed by researchers in Ontario on 30,000-year-old bacteria whose DNA has been recovered from the Yukon permafrost shows that they were able to resist antibiotics. Experts had long predicted this on theoretical grounds, but they say the new finding underlines the need to use antibiotics sparingly, given that the genes for antibiotic resistance are ubiquitous and can easily be promoted by antibiotics.
