  • How Pathogenic Bacteria Hang On to Mucosa and Avoid Exfoliation
    Mucous surfaces in the nose, throat, lungs, intestine, and genital tract are points of first contact for many pathogens. As a defensive strategy, most animals (and humans) can rapidly exfoliate these surfaces (i.e., shed the surface layer) to get rid of any attached ...More

  • When Beneficial Bacteria 'Knock' But No One is Home
    The community of beneficial bacteria that live in our intestines, known as the gut microbiome, are important for the development and function of the immune system. There has been growing evidence that certain probiotics--therapies that introduce beneficial bacteria into the ...More

  • Bacteria Use Traffic Cop-Like Mechanism to Infect Gut
    A study has found that a syringe-like device used to invade intestinal cells also acts as a traffic cop -- directing bacteria where to go and thereby enabling them to efficiently carry out infection.  The findings by researchers at Washington State University and ...More

  • Scientists Reveal the Secret of Antibiotic-Resistant Bacteria
    Researchers from the Scientific Research Institute of Physical-Chemical Medicine, MIPT, the company M&S Decisions and the research department of Yandex have built a computer model of the interaction between different bacteria, and between bacteria and the gut wall. This ...More

  • Scientists Sharpen View of Gene Transfer Between Pathogenic Bacteria
    Bacteria possess the ability to take up DNA from their environment, a skill that enables them to acquire new genes for antibiotic resistance or to escape the immune response. Scientists have now mapped the core set of genes that are consistently controlled during DNA uptake ...More

  • Pancreatic Cancer Risk Tied to Specific Mouth Bacteria
    The presence of certain bacteria in the mouth may reveal increased risk for pancreatic cancer and enable earlier, more precise treatment. This is the main finding of a study led by researchers at NYU Langone Medical Center and its Laura and Isaac Perlmutter Cancer Center to ...More

  • Great Willow Herb May Be Effective Against Multidrug-Resistant Bacteria
    Although often considered a weed, due to its anti-inflammatory and antioxidant properties, willow herb has long enjoyed a solid reputation for easing problems of the prostate gland and urinary tract. New tests confirm that combining some of the commonly used antibiotics ...More

  • Bacteria's Vulnerability Uncovered by Single Molecule Chemistry
    Drug-resistant bacteria are fast becoming one of the big worries of the 21st century. Now researchers at the University of Copenhagen have discovered a previously unknown weakness -- an Achilles' heel of bacteria. Their discovery, a crucial step in bacteria's energy ...More

  • Keeping Ribosomes Stuck May Stop Virulent Bacteria Strain
    Compounds that stop a cellular rescue operation for stuck ribosomes may bolster the nation's defenses against biowarfare and bioterrorism, as well as create alternative antibiotics to handle increasingly resistant pathogens, according to a team of researchers. In a study of ...More

  • Images Reveal Bacterial Motor Parts in Unprecedented Detail
    Many bacteria swim using flagella -- long tails that are attached to tiny motors made of proteins, just tens of nanometres wide. These motors spin the flagella, which work as nanoscale propellers to drive the bacterium forward. ...More
