Washington, DC – July 20, 2015 - Biofilms are tough, opportunistic, highly antibiotic resistant bacterial coatings that form on catheters and on medical devices implanted within the body. University of Maryland investigators have now shown that a “messenger molecule” produced by the opportunistic human pathogen, Pseudomonas aeruginosa, encourages bacteria to colonize catheters in the bladders of laboratory mice, where they form biofilms. The research appears July 20th in the Journal of Bacteriology, a publication of the American Society for Microbiology.
Washington, DC - July 17, 2015 - The success of probiotics for boosting human health may depend partly upon the food, beverage, or other material carrying the probiotics, according to research published on July 10th in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
Washington, DC —July 14, 2015—Multiple species of bacteria working together in healthy guts are responsible for keeping out nasty bacterial invader, Clostridium difficile, a hospital-acquired culprit responsible for 15,000 deaths each year. The study, published this week in mBio, the online open-access journal of the American Society for Microbiology, could lead to tests to predict which hospital patients are at highest risk of infection and better management of infections.
Washington, DC - July 15, 2015 - For decades, researchers have worked to improve cacao fermentation by controlling the microbes involved. Now, to their surprise, a team of Belgian researchers has discovered that the same species of yeast used in production of beer, bread, and wine works particularly well in chocolate fermentation. The research was published ahead of print July 6th in Applied and Environmental Microbiology, a publication of the American Society for Microbiology.
Washington, D.C. - July 6, 2015 - Those bacteria that require iron walk a tightrope. Iron is essential for their growth, but too much iron can damage DNA and enzymes through oxidation. Therefore, bacteria have machinery to maintain their intracellular iron within the “Goldilocks zone.” Now Theresa D. Ho, PhD, and Craig D. Ellermeier, PhD shed new light on how the pathogen, Clostridium difficile, which is the most common cause of hospital-acquired infectious diarrhea, regulates iron. The research is published online ahead of print July 6 in the Journal of Bacteriology, a publication of the American Society for Microbiology.
