NIST, Army researchers pave the way for anthrax spore standards
Researchers from the National Institute of Standards and Technology (NIST) and the U.S. Army Dugway (Utah) Proving Ground have developed reliable methods based on DNA analysis to assess the concentration and viability of anthrax spores after prolonged storage. view more (2008-04-16)
Bacillus thuringiensis - Bacterial Insecticide
Microbiologists in Europe have played a major role in developing the Bacillus thuringiensis story, as they have in many areas of research. FEMS, The Federation of European Microbiological Societies, is now embarking on a series of major European Congresses bringing together scientists from all parts of Europe and providing a forum for the... view more...

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)
Novel approach strips staph of virulence
An international team of researchers supported by the National Institutes of Health (NIH) has blocked staph infections in mice using a drug previously tested in clinical trials as a cholesterol-lowering agent. view more (2008-02-15)
New light-sensing ability discovered in disease-causing bacteria
The bacteria that cause brucellosis can sense light and use the information to regulate their virulence, according to a study in the August 24 issue of the journal Science. view more (2007-08-24)
Engineered protein effective against Staphylococcus aureus toxin
A research team led by the University of Illinois has developed a treatment for exposure to enterotoxin B, a noxious substance produced by the Staphylococcus aureus bacterium. view more (2007-05-22)
Tuberculosis: The bacillus takes refuge in adipose cells
A team from the Institut Pasteur has recently shown that the tuberculosis bacillus hides from the immune system in its host's fat cells. view more (2006-12-21)
Two novel species of bacteria isolated from oil wells
Oilfields usually represent extreme environments, where physicochemical conditions appear at first sight to be generally unsuitable for living organisms to develop. However, these environments, usually poor in nitrates and oxygen, harbour a rich diverse community of microorganisms. The most widely represented and best-known types are... view more... (2004-11-23)
Where man boldly goes, bacteria follow
Life in outer space is an absolute certainty, and it is likely to be more familiar than we might think, according to an article in the May issue of Microbiology Today. Ever since the start of the space race we have sent more than just satellites and astronauts into space: spacecraft are not routinely decontaminated and are teeming with microbial... view more...

Silicon May Have Been The Key To Start Of Life On Earth
A scientist at the University of Sheffield has discovered that silicon may have been key to the establishment of life on earth. Until now it has generally been thought that bacteria do not interact with silicon, but Dr Milton Wainwright and his team at the University's Department of Molecular Biology and Biotechnology, has found that this is not... view more...

Studies highlight MRSA evolution and resilience
Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are caused primarily by a single strain-USA300-of an evolving bacterium that has spread with "extraordinary transmissibility" throughout the United States during the past five years, according to a new study led by National Institutes of Health (NIH)... view more...

Colorful bacteria more dangerous
A new study in the July 18 issue of The Journal of Experimental Medicine shows that gold-colored bacteria are more harmful than their unpigmented relatives. A group of scientists led by Victor Nizet (UCSD, San Diego, CA) have discovered that the molecules that give certain bugs their color also help them resist attack by immune cells called... view more...

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...

Using evolution, UW team creates a template for many new therapeutic agents
By guiding an enzyme down a new evolutionary pathway, a team of University of Wisconsin-Madison researchers has created a new form of an enzyme capable of producing a range of potential new therapeutic agents with anticancer and antibiotic properties. view more (2007-09-10)
Solution to bacterial mystery promises new drugs
A 25-year quest to identify the first biochemical step that many disease-causing bacteria use to build their membranes has led to a discovery that holds promise for effective, new antibiotics against these bacteria. view more (2006-09-01)
New potential drug target in tuberculosis
Tuberculosis remains one of the deadliest threats to public health. Every year two million people die of the disease, which is caused by the microorganism Mycobacterium tuberculosis. view more (2006-05-30)
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)
Studies Suggest New Targets for Tuberculosis Treatments
With the hope of designing more effective treatments for tuberculosis (TB), scientists from the U.S. Department of Energy's Brookhaven National Laboratory and collaborating institutions have published the first detailed reports on the biochemistry and structure of a protein-cleaving complex that is essential to the TB bacterium's survival. view more (2006-03-07)
How Do Bacteria Swim? Brown Physicists Explain
Imagine yourself swimming in a pool: It's the movement of your arms and legs, not the viscosity of the water, that mostly dictates the speed and direction that you swim. view more (2008-11-20)
Gas-guzzling bacteria
The discovery of a new soil bacterium that consumes methane by oxidising it under atmospheric conditions is reported in Nature, out today. In well-drained soils, these methane-oxidising bacteria can reduce atmospheric levels of methane by 10 per cent. Methane is an important greenhouse gas, and over the last 200 years its concentration in the... view more... (2000-05-10)
