New Immunization Strategy Could Prevent Gastrointestinal Disease

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 […]

These Nanoscale Protein Power Lines Are Made By Microbes

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, […]

Microbes Implicated As Major Cause Of Alzheimer’s Disease

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 […]

Dietary Gut Microbes May Prevent Malnutrition In Children

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 […]

Bacterial Circadian Clocks Set By Metabolism, Not Light

Most organisms on Earth, from bacteria to humans, possesses a circadian clock, a biological mechanism that synchronizes activities such as rest or growth to daily changes in a 24-hour day. Although commonly thought to be tied to the day-night cycle, the circadian clock actually appears to be set by metabolic rhythms, according to a new […]
