Drug-resistant superbugs are "a ticking time-bomb not only for the UK but also for the world," England's top medical official warns in her first annual report, released today. Chief Medical Officer Dame Sally Davies writes that increasing bacterial resistance to antibiotics could turn routine operations into life-threatening procedures if infections become difficult to treat, and in the absence of tougher restrictions on the use of antibiotics—not just in prescriptions for humans but in the agriculture and meat industries—and concerted efforts to discover new drugs—there have been no new antibiotic classes since 1987—we could be heading toward "a health system not dissimilar from the early 19th century." Of particular concern are so-called "Gram-negative" bacteria like E Coli, which are now being seen in the UK more often than previously-hyped drug-resistant superbugs like MRSA, and are more common in the old, young, and immune-compromised. "This is your own gut bugs turning on you," Professor Mike Sharland tells The Guardian. "Between 10% and 20% are resistant to drugs." Davies suggests that the UK divert more resources toward developing antibiotics, and sound a global alarm on the issue: "This threat is arguably as important as climate change," she writes. Meanwhile, in the U.S., pet frogs are giving kids salmonella. [Guardian | Independent | Reuters | GIF via]
