Study indicates different treatment may be needed for infection-related breathing problems
New research suggests that different treatments may be needed for chronic asthma, depending on whether it results from allergies or lung infections. view more (2007-01-31)
A salty tale: New bacterial genome sequenced from ancient salterns
Tourists in Spain often stop to ogle the country's many saltwater lagoons, used to produce salt since Roman times. Scientists, too, admire these saltern crystallizers-and even more so, the microbes that manage to survive in such briny environs. view more (2005-12-06)
Immune system discovery could aid fight against TB
A key aspect of how the body kicks the immune system into action against tuberculosis is revealed in research published today. view more (2006-10-23)
Microbes convert 'Styrofoam‚—˘' into biodegradable plastic
Bacteria could help transform a key component of disposable cups, plates and utensils into a useful eco-friendly plastic, significantly reducing the environmental impact of this ubiquitous, but difficult-to-recycle waste stream. view more (2006-02-24)
Curbing C. difficile's toxin production
As if being admitted to the hospital weren't bad enough, patients, once admitted, are at higher risk of becoming infected with a "superbug" bacterium, Clostridium difficile (C. difficile). view more (2007-09-06)
Researchers identify new leprosy bacterium
A new species of bacterium that causes leprosy has been identified through intensive genetic analysis of a pair of lethal infections, a research team reports in the December issue of the American Journal of Clinical Pathology. view more (2008-11-25)
Structure of cog at the hub of metabolism reveals anti-ageing function
The structure of a key energy-releasing enzyme found in all animals is designed to minimise free radical production, an international team of researchers report in the journal Science today. In a startling feat of structural biology, the team visualised the entire molecular structure of succinate dehydrogenase in the bacterium E. coli, allowing... view more... (2003-01-30)
Researchers reveal mystery of bacterial magnetism
Scientists at the Naval Research Laboratory (NRL) and Purdue University have shed light on one of microbiology's most fascinating mysteries-why some bacteria are naturally magnetic. view more (2006-10-23)
New anthrax inhibitor could combat antibiotic-resistant strains
In a new approach to treating anthrax exposure, a team of scientists has created an inhibitor designed to tackle the growing threat of antibiotic-resistant strains. view more (2006-08-29)
Lab-on-a-chip detects ammonia in human breath
A lab-on-a-chip that is sensitive enough to detect just a tiny ammount of ammonia in human breath has been developed by Björn Timmer of University of Twente in The Netherlands. Ammonia is an indicator for the development of a bacterial infection in the stomach. The tiny dimensions of this lab-on-a-chip have several advantages: it just needs a... view more... (2004-05-28)
Predatory bacterial swarm uses rippling motion to reach prey
Like something from a horror movie, the swarm of bacteria ripples purposefully toward their prey, devours it and moves on. view more (2008-10-30)
Bacteria for plague control in agriculture
Bacillus thuringiensis, a spore bacteria discovered in 1901 by the Japanese scientist Ishiwata and, ten years later, by the German scientist Berliner came across his findings. It is the micro-organism most used as a bio-insecticide throughout the world. It is a bacterium found naturally in ecosystems, frequently on floors and on the surface of... view more... (2003-02-14)
Small-scale parasitic battles may have epic evolutionary proportions
Scientists at MIT's Department of Civil and Environmental Engineering and the Technion Israel Institute of Technology have for the first time recorded the entire genomic expression of both a host bacterium and an infecting virus over the eight-hour course of infection. view more (2007-09-06)
NYU dental researchers find link between C-section delivery and higher risk of cavities in newborns
A new study by NYU dental researchers suggests that women with dental caries (cavities) who deliver Caesarean-section babies should pay special attention to their newborns' oral health. view more (2005-08-24)
Urban slum conditions are a source of leptospirosis
A study conducted in an urban slum setting in Salvador, Brazil has found that open sewers, accumulations of refuse, and inadequate floodwater drainage are acting as sources for transmission of the disease leptospirosis. The study is published in this week's PLoS Neglected Tropical Diseases. view more (2008-04-23)
Supersized 'island' of resistance genes discovered in an infectious bacterium
Researchers have discovered a cluster of 45 genes coding for antibacterial drug resistance in the bacterium, Acinetobacter baumannii, a major cause of hospital-acquired infections worldwide. view more (2006-01-13)
Secret of Worm's Poison Pill Box Protein Could Produce New Natural Insecticide
Researchers at the University of Warwick have discovered how a protein from a bacterium acts like a cunningly designed poison pill box that could now be used as a basis of a new range of natural insecticides. view more (2007-03-13)
Salmonella: Trickier than we imagined
Salmonella is serving up a surprise not only for tomato lovers around the country but also for scientists who study the rod-shaped bacterium that causes misery for millions of people. view more (2008-06-16)
Two bacteria better than one in cellulose-fed fuel cell
No currently known bacteria that allow termites and cows to digest cellulose, can power a microbial fuel cell and those bacteria that can produce electrical current cannot eat cellulose. view more (2007-07-30)
From foe to friend: Researchers use salmonella as a way to administer vaccines in the body
Researchers at the Biodesign Institute at Arizona State University have made a major step forward in their work to develop a biologically engineered organism that can effectively deliver an antigen in the body. The researchers report that they have been able to use live salmonella bacterium as the containment/delivery method for an antigen. view more (2008-07-09)
