Researchers discover RNA repair system in bacteria
In new papers appearing this month in Science and the Proceedings of the National Academy of Sciences, University of Illinois biochemistry professor Raven H. Huang and his colleagues describe the first RNA repair system to be discovered in bacteria. view more (2009-10-13)
Researchers identify mechanism that helps bacteria avoid destruction in cells
Infectious diseases currently cause about one-third of all human deaths worldwide, more than all forms of cancer combined. Advances in cell biology and microbial genetics have greatly enhanced understanding of the cause and mechanisms of infectious diseases. view more (2009-10-12)
Scientists take step toward simple and portable tuberculosis tests for developing world
Two billion people worldwide carry the pathogen that causes tuberculosis (TB), and most of them do not even know they are infected. This is because some 90 percent of people with TB have "latent" infections. They have no symptoms, they can't spread the disease to others and the bug remains dormant in their lungs -- often for years. view more (2009-10-09)
UBC researchers identify key behavior of immune response to Listeria
A team of University of British Columbia microbiologists has identified a key defence mechanism used by the immune system against Listeria with strong implications for the future development of vaccines. view more (2009-10-06)
Understanding a cell's split personality aids synthetic circuits
As scientists work toward making genetically altered bacteria create living "circuits" to produce a myriad of useful proteins and chemicals, they have logically assumed that the single-celled organisms would always respond to an external command in the same way. view more (2009-10-05)
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)
UT Knoxville and ORNL researchers reveal key to how bacteria clear mercury pollution
Mercury pollution is a persistent problem in the environment. Human activity has lead to increasingly large accumulations of the toxic chemical, especially in waterways, where fish and shellfish tend to act as sponges for the heavy metal. view more (2009-10-02)
Taking sharper aim at stomach ulcer bacteria
Scientists are reporting discovery of a much sought after crack in the armor of a common microbe that infects the stomachs of one-sixth of the world's population, causing stomach ulcers and other diseases. view more (2009-10-01)
Light, photosynthesis help bacteria invade fresh produce
Exposure to light and possibly photosynthesis itself could be helping disease-causing bacteria to be internalized by lettuce leaves, making them impervious to washing, according to research published in the October issue of the journal Applied and Environmental Microbiology. view more (2009-09-29)
Yale engineers track bacteria's kayak paddle-like motion for first time
Yale engineers have for the first time observed and tracked E. coli bacteria moving in a liquid medium with a motion similar to that of a kayak paddle. view more (2009-09-28)
McMaster researchers discover a new antibacterial lead
Antibiotic resistance has been a significant problem for hospitals and health-care facilities for more than a decade. But despite the need for new treatment options, there have been only two new classes of antibiotics developed in the last 40 years. view more (2009-09-28)
Fish fend off invading germs with an initial response similar to the one found in people
Since the human response to infection is highly complex, research to understand how people fight infection is facilitated by studying how similar processes occur in simpler organisms. view more (2009-09-24)
How Good Are Indicator Bacteria at Predicting Pathogens in Recreational Water?
Bacteria commonly used to indicate health risks in recreational waters might not be so reliable after all. Pathogenic E. coli were pervasive in stream-water samples with low concentrations of fecal indicator bacteria. view more (2009-09-23)
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)
Gut Ecology in Transplant Patients
Small-bowel transplant patients with an ileostomy -- an opening into their small bowel -- have a very different population of bacteria living in their gut than patients whose ileostomy has been closed, researchers from UC Davis and Georgetown University Medical Center have found. view more (2009-09-16)
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)
Disease-causing Escherichia coli: 'I will survive'
Strains of Escherichia coli bacteria that cause food poisoning have been shown to have marked differences in the numbers of genes they carry compared to laboratory strains of E. coli. view more (2009-09-09)
New biosensor can detect bacteria instantaneously
A research group from the Rovira i Virgili University (URV) in Tarragona has developed a biosensor that can immediately detect very low levels of Salmonella typhi, the bacteria that causes typhoid fever. view more (2009-09-09)
Casting out devils
In the scientific journal PLoS ONE, Sara Bartels and Siegfried Weiss of the Helmholtz Centre for Infection Research (HZI) in Braunschweig, Germany now show how the bacteria migrate into tumours. view more (2009-09-09)
