Exploring the final frontier: Disease proposed as major barrier to Mars and beyond
New research published in the Journal of Leukocyte Biology suggests that prolific virulence and growth of bacteria, coupled with reduced production of antibodies could limit future space travel. view more (2009-10-30)
TraDIS technique tackles typhoid
For the first time, researchers are able to look at the need for every gene in a bacterial cell in a single experiment. The new method will transform the study of gene activity and the search for weaknesses in bacterial armouries. view more (2009-10-16)
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)
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)
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)
Eating less red meat can prevent cancer, heart attacks and global warming
Raising livestock also accounts for around 18% of greenhouse gases. It is therefore possible to act against climate change and reduce cardiovascular and cancer deaths, by cutting the production and consumption of 'red meat' from these animals. view more (2009-08-31)
Enzyme necessary for DNA synthesis can also erase DNA
In this week's edition of Proceedings of the National Academy of Sciences, PNAS, Uppsala University scientists describe a new mechanism behind an important process that causes a rapid reduction of DNA in the chromosomes of bacteria. view more (2009-06-09)
Salmonella's sweet tooth predicts its downfall
For the first time UK scientists have shown what the food poisoning bug Salmonella feeds on to survive as it causes infection: glucose. view more (2009-05-20)
Simple device can ensure food gets to the store bacteria free
A Purdue University researcher has found a way to eliminate bacteria in packaged foods such as spinach and tomatoes, a process that could eliminate worries concerning some food-borne illnesses. view more (2009-03-03)
U of Minnesota study finds confidence in food safety plunges in wake of peanut butter contamination
Fewer than one in four consumers now believe the U.S. food supply is safer than it was a year ago, according to new data from the University of Minnesota's Food Industry Center. view more (2009-02-25)
New insights into a leading poultry disease and its risks to human health
Biodesign Institute at Arizona State University associate research scientist Melha Mellata, a member of professor Roy Curtiss' team, is leading a USDA funded project to develop a vaccine against a leading poultry disease called avian pathogenic E. coli (APEC). view more (2009-01-27)
From poison to prevention
One of the major challenges in modern vaccinology is to engineer vectors that are highly infectious, yet don't cause illness. Trickier still is to ensure that such weapons against infectious disease can be safely disarmed, once their immunogenic work is done. view more (2009-01-13)
Unpasteurized milk poses health risks without benefits
With disease outbreaks linked to unpasteurized milk rising in the United States, a review published in the January 1, 2009 issue of Clinical Infectious Diseases examines the dangers of drinking raw milk. view more (2008-12-17)
The medium is the message: Manipulating salmonella in spaceflight curtails infectiousness
Infectious pathogens like Salmonella typhimurium employ a startling array of techniques to skillfully outwit the body's defense mechanisms and produce illness. view more (2008-12-12)
Biosolids Microbes Pose Manageable Risk to Workers
Class B biosolids are sewage sludges that have been treated to contain fewer than 2.0 x 106 fecal coliforms/dry gram. view more (2008-10-28)
Making flies sick reveals new role for growth factors in immunity
A Salmonella infection is not a positive experience. However, by infecting the common laboratory fruit fly Drosophila melanogaster with a Salmonella strain known for causing humans intestinal grief, researchers in the School of Life Sciences at Arizona State University have shed light on some key cell regulatory processes - with broad implications... view more...

What is the function of NOD2 in colonic epithelial cells?
NOD2 is a cytosolic pattern recognition receptor similar in structure and function to Toll like receptors (TLRs). It can recognize and respond to a component found in the cell wall of bacteria, muramyl dipeptide (MDP), and has been shown to play an important role in the innate immune response of macrophages to bacterial infections. view more (2008-10-23)
UCSB researchers develop cross-protective vaccine
Doctors have always hoped that scientists might one day create a vaccination that would treat a broad spectrum of maladies. They could only imagine that there might be one vaccine that would protect against, say, 2,500 strains of Salmonella. view more (2008-10-22)
New study shows health benefits of probiotic could extend to the entire body
Data from a recent study demonstrate the anti-inflammatory and pathogen protection benefits of Bifidobacterium infantis 35624 a probiotic bacterial strain of human origin. view more (2008-08-25)
