Factors from common human bacteria may trigger multiple sclerosis
Current research suggests that a common oral bacterium may exacerbate autoimmune disease. The related report by Nichols et al, "Unique Lipids from a Common Human Bacterium Represent a New Class of TLR2 Ligands Capable of Enhancing Autoimmunity," appears in the December 2009 issue of The American Journal of Pathology. view more (2009-11-24)
Sweet as can be: how E. coli gets ahead
Scientists at the University of York have discovered how certain bacteria such as Escherichia coli have evolved to capture rare sugars from their environment giving them an evolutionary advantage in naturally competitive environments like the human gut. view more (2009-11-12)
Probiotic Found to Be Effective Treatment for Colitis In Mice
The probiotic, Bacillus polyfermenticus, can help mice recover from colitis, a new study has found. view more (2009-10-26)
The white stuff: Marine lab team seeks to understand coral bleaching
With technology similar to that used by physicians to perform magnetic resonance imaging (MRI) scans, researchers from six institutions-including the National Institute of Standards and Technology (NIST)-working at the Hollings Marine Laboratory (HML) in Charleston, S.C., are studying the metabolic activity of a pathogen shown to cause coral... view more...

Eating right, not supplements, is best at keeping your good bacteria healthy, dietitian says
Healthy eating, not supplements, is the best way to keep the good bacteria in your gut healthy, says a dietitian and researcher. view more (2009-10-22)
Team finds a better way to watch bacteria swim
Researchers have developed a new method for studying bacterial swimming, one that allows them to trap Escherichia coli bacteria and modify the microbes' environment without hindering the way they move. view more (2009-10-05)
Caltech scientists get detailed glimpse of chemoreceptor architecture in bacterial cells
Using state-of-the-art electron microscopy techniques, a team led by researchers from Caltech has for the first time visualized and described the precise arrangement of chemoreceptors-the receptors that sense and respond to chemical stimuli-in bacteria. view more (2009-09-25)
New test quickly ID's active TB in smear-negative patients
Active tuberculosis can be rapidly identified in patients with negative sputum tests by a new method, according to European researchers. Active tuberculosis (TB) is the seventh-leading cause of death worldwide, and while the diagnosis of active TB can be rapidly established when the bacteria can be identified on sputum microscopy, in about half of... view more...

UCF professor finds new way deadly food-borne bacteria spread
University of Central Florida Microbiology Professor Keith Ireton has uncovered a previously unknown mechanism that plays an important role in the spread of a deadly food-borne bacterium. view more (2009-09-21)
Weill Cornell Researchers Discover New Anti-Tuberculosis (TB) Compounds
Attempts to eradicate tuberculosis (TB) are stymied by the fact that the disease-causing bacteria have a sophisticated mechanism for surviving dormant in infected cells. view more (2009-09-17)
Evolution still scientifically stable
An international team of researchers, including Monash University biochemists, has discovered evidence at the molecular level in support of one of the key tenets of Darwin's theory of evolution. view more (2009-09-14)
Better immune defense against anthrax
Scientists discover a gene in anthrax-causing bacteria may help defend against this form of bio-warfare. view more (2009-09-09)
Making bacteria make useful proteins
By adapting a single protein on the surface of the bacterium Caulobacter crescentus, researchers at the University of British Columbia have turned it into a protein production factory, making useful proteins that can act as vaccines and drugs. view more (2009-09-08)
New genomic model defines microbes by diet -- provides tool for tracking environmental change
In line with the U.S. Department of Energy (DOE) interest in characterizing the biotic factors involved in global carbon cycling, the DOE Joint Genome Institute (JGI) characterizes a diverse array of plants, microorganisms, and the communities in which they reside to inform options for reducing and stabilizing atmospheric greenhouse gases. view more (2009-09-08)
UTSA biology researchers demystify elusive war zone bacterium
Tao Weitao, a researcher in the College of Sciences' Department of Biology at the University of Texas at San Antonio is making great strides in a project that was funded one year ago by the San Antonio Area Foundation. view more (2009-08-17)
Uncovering the secrets of ulcer-causing bacteria
A team of researchers from Boston University, Harvard Medical School and Massachusetts Institute of Technology recently made a discovery that changes a long held paradigm about how bacteria move through soft gels. view more (2009-08-13)
Pinhead-size worms + robot = new antibiotics
In an advance that could help ease the antibiotic drought, scientists in Massachusetts are describing successful use of a test that enlists pinhead-sized worms in efforts to discover badly needed new antibiotics. view more (2009-08-06)
Higher drug doses needed to defeat tuberculosis, UT Southwestern researchers report
The typical dose of a medication considered pivotal in treating tuberculosis effectively is much too low to account for modern-day physiques, UT Southwestern Medical Center researchers said. view more (2009-07-30)
Pinpointing cause of colic: UT Houston research identifies organism that could trigger constant crying
Researchers at The University of Texas Health Science Center at Houston say one organism discovered during their study may unlock the key to what causes colic, inconsolable crying in an otherwise healthy baby. view more (2009-07-27)
Hopkins-designed animal TB 'tracker' to speed drug and vaccine studies
Johns Hopkins researchers have developed a novel way to monitor in real time the behavior of the TB bacterium in mouse lungs noninvasively pinpointing the exact location of Mycobacterium tuberculosis. view more (2009-07-23)
