Antibiotic resistance is spreading fast all over the world. When infectious bacteria mutate in a certain way and then multiply, they can become resistant to even the most powerful drugs. But research has revealed a worrying alternative way that antibiotic resistance can spread: an organism that passes on its resistance on to other living bacteria… Read more

Researchers from MIT and the University of California at Irvine have developed a new strategy to immunize against microbes that invade the gastrointestinal tract, including Salmonella, which causes more foodborn illness in the United States than any other bacteria. The researchers targeted a molecule that Salmonella and other bacteria secrete to scavenge iron, which is… Read more

Very small fibers made by a bacteria have the unique property of transporting charges at speeds of 1 billion electrons per second. The fibers are hair-like protein filaments called pili. Says Gemma Reguera, lead author and Michigan State University microbiologist: “This microbial nanowire is made of but a single peptide subunit. Being made of protein… Read more

A worldwide team of senior scientists and clinicians have come together to produce an editorial which indicates that certain microbes, a specific virus and two specific types of bacteria, (herpes simplex virus type 1, Chlamydia pneumoniae, and several types of spirochaete) ,are major causes of Alzheimer’s disease. Their paper stresses the urgent need for further… Read more

There’s evidence from two new studies that it might be possible to treat and even prevent malnutrition in children, which kills more than 2 million kids every year, by manipulating the makeup of microbes in the gut. Both studies were carried out in germ-free mice with gut microbes transferred from either healthy or malnourished young… Read more
