  • Unlocking the Mysteries of Bacterial Cell Cycle Regulation
    As part of their long-term investigation of regulatory factors in the bacterial cell cycle, molecular biologists at the University of Massachusetts Amherst now report finding a surprising new role for one factor, CpdR, an adaptor that helps to regulate selective protein ...More

  • Method Reveals What Bacteria Sense in Their Surroundings
    A new, rapid method is helping detect how bacteria sense and respond to changes in their environment. Bacteria can pick up external signals, which then relay to internal signaling pathways that direct their behavior. This surveillance also can trigger survival tactics for a ...More

  • Discovery of How Bacteria Survive Antibiotics May Improve Treatment of Infectious Diseases
    Infectious diseases kill more people worldwide than any other single cause, but treatment often fails because a small fraction of bacterial cells can transiently survive antibiotics and recolonize the body. A study published June 4 in Molecular Cell reveals that these ...More

  • Bacteria May Cause Type 2 Diabetes
    Bacteria and viruses have an obvious role in causing infectious diseases, but microbes have also been identified as the surprising cause of other illnesses, including cervical cancer (human papillomavirus) and stomach ulcers (H. pylori bacteria). A new study by University ...More

  • Rockefeller Scientists Resolve Debate Over How Many Bacteria Fight Off Invaders
    Every inch of our body, inside and out, is covered with bacteria. In fact, the human body carries 10 times the number of bacterial cells as human cells. Many are our friends, helping us digest food and fight off infections, for instance. But much about these abundant ...More

  • Iowa State, Ames Lab Scientists Describe Protein Pumps That Allow Bacteria to Resist Drugs
    Research teams led by Edward Yu of Iowa State University and the Ames Laboratory have described the structures of two proteins they believe pump antibiotics from bacteria, allowing the bacteria to resist medications. One of the protein pumps, known as MtrF, is believed to ...More

  • Bacterial 'Memory' Targets Invading Viruses
    One of the immune system's most critical challenges is to differentiate between itself and foreign invaders -- and the number of recognized autoimmune diseases, in which the body attacks itself, is on the rise. But humans are not the only organisms contending with "friendly ...More

  • How a Bacterial Cell Recognizes Its Own DNA
    It may come as a bit of a surprise to learn that bacteria have an immune system - in their case to fight off invasive viruses called phages. And like any immune system -- from single-celled to human -- the first challenge of the bacterial immune system is to detect the ...More
