New Superbug Resistant To All Antibiotics Now Found Worldwide
Last week, I shared scary news of a new gene called mcr-1 conferring resistance to our last-ditch antibiotic, colistin. The gene was found in China with spread to the Netherlands. I raised concerns, too, about imports of some foods from China. Several new reports in the Lancet Infectious Diseases suggest the spread of this newly found resistance gene, mcr-1, is far worse than it initially appeared. Here are the latest findings from several just-released studies...

Research to Help Fight Multi-Resistant Bacteria
An international collaboration led by scientists from The University of Western Australia has uncovered the three-dimensional molecular structure of a protein, called EptA, which is responsible for multi-drug resistance in many disease-causing bacteria. Multi-drug resistance in bacteria has been identified as a major worldwide public health concern by the World Health Organization. Multi-drug resistant bacteria are responsible for approximately 700,000 deaths per year, a figure which the WHO says could reach 10 million by the year 2050...

The Time to Stop Giving Antibiotics to Cows, Pigs, and Chickens Is Now
Antibiotic resistance has been blamed for at least 2 million illnesses and 23,000 deaths in the US. Researchers are especially concerned about the widespread use of antibiotics in raising cattle, pigs, and other animals for food production. The drugs help the animals bulk up, which boosts their value, but experts warn that they can also promote antibiotic resistance. I’ve asked two guest authors, Josh Bloom and Dr. David Shlaes of the American Council on Science and Health, to share their insights on this issue. They warn that more needs to be done to curb the use of antibiotics in food-producing animals.
