Discovery by Canadian researchers of how bacteria become resistant to antibiotics could lead to more effective drugs

Ontario researchers say they have discovered how bacteria become resistant to antibiotics, a finding they say could help combat the growing problem. Maikel Rheinstadter, a physics professor with McMaster University in Hamilton, and Andree Khondker, an undergraduate biochemistry student, said they found bacteria fight off antibiotics by stiffening their cell membranes and changing the barrier’s… Read More »

Nanoparticles in food can alter the behavior of gut bacteria

New research on nanoparticles in food has yielded fresh insights about their impact on gut bacteria. Nanoparticles may influence gut bacteria (which are shown here under the electron microscope). Researchers from the University Medical Center of Mainz in Germany and colleagues from other centers in Germany, Austria, and the United States have discovered that the… Read More »

Stethoscopes loaded with bacteria, including the one that causes Staph infection

The stethoscope has long been an iconic symbol of health care used for listening to the heart, intestines, lungs and blood flow. But while it’s an invaluable tool that every medical student must learn to use, it seems they didn’t learn how to clean them. That’s according to a new study that analyzed the DNA… Read More »
