New method for testing condition of seeds
Wageningen UR develops method for testing condition of seeds Flow-cytometry, the technique for studying large numbers of individual cells in a fluid, can be combined with the use of special fluorescent colouring agents to form a valuable method of determining the health of seeds and seed consignments. This is shown in the thesis with which... view more... (2001-04-03)
Rhode Island Hospital study finds local retail meat safe from antibiotic-resistant organisms
Rhode Island Hospital researchers report that findings from a new study of retail meat in the Providence, RI area indicate little to no presence of antibiotic-resistant bacteria. view more (2008-10-29)
DNA of good bacteria drives intestinal response to infection
A new study shows that the DNA of so-called "good bacteria" that normally live in the intestines may help defend the body against infection. view more (2008-10-03)
House dust may protect against allergic disease early in life
Endotoxin, a toxic substance made by certain types of bacteria, may reduce the risk of developing the allergic skin condition eczema or wheezing in children if they are exposed to it up to age 3. view more (2007-05-21)
Probiotics ease gut problems caused by long term stress
Probiotics may help to reduce gut symptoms caused by long term stress, indicates research published ahead of print in the journal Gut. view more (2006-04-25)
A New Category of Antibiotics May Present a Fresh Threat to Public Health
Bacteria have developed resistance to all antibiotics in use today, and this is causing a major health problem. However, a remarkable range of new antibiotics, called cationic antimicrobial peptides (AMPs), is attracting increasing interest as a key weapon in the fight against bacterial infection. They are based on toxic proteins that are part of... view more... (2003-06-13)
New drug-resistant strain of salmonella identified (p 1285)
Researchers from Taiwan report the identification of a new form of drug-resistant salmonella bacterium in this week's issue of THE LANCET. Salmonella enterica serotype choleraesuis usually causes infections that require antimicrobial treatment. Multidrug-resistant strains have been identified, but the antimicrobial ceftriaxone has been effective... view more... (2004-04-14)
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)
Cranberry juice creates energy barrier that keeps bacteria away from cells, study shows
For generations, people have consumed cranberry juice, convinced of its power to ward off urinary tract infections, though the exact mechanism of its action has not been well understood. view more (2008-07-22)
Trojan horse strategy defeats drug-resistant bacteria
A new antimicrobial approach can kill bacteria in laboratory experiments and eliminate life-threatening infections in mice by interfering with a key bacterial nutrient, according to research led by a University of Washington scientist. The joint project, conducted at the UW, the University of Iowa, and the University of Cincinnati, will be... view more... (2007-03-19)
Lack of sleep activates body's defence mechanisms
A lack of sleep is considered a threat situation, which activates the body's defence mechanisms. This is the same type of response that protects the body against viruses and bacteria as well as in stress situations. view more (2005-03-16)
Antibiotics alter the normal bacterial flora in humans
Microbes researchers highlight drawbacks of antibiotics Antibiotics alter the normal bacterial flora in humans Bacteria that are resistant to antibiotics can live in the human intestines for at least one year. Professor Charlotta Edlund from the Karolinska Institutet in Stockholm, Sweden, and Research Professor Pentti Huovinen from the National... view more... (2004-03-17)
ETH Zurich: Fast and Cheap Detection of Bacteria
Carbohydrates displayed on the surface of cells play critical roles in cell-cell recognition, adhesion, signaling between cells, and as markers for disease progression. Neural cells for instance use carbohydrates to facilitate development and regeneration and viruses recognize carbohydrates to gain entry into host cells. Identification of the... view more...

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)
Scientists equip bacteria with custom chemo-navigational system
Using an innovative method to control the movement of Escherichia coli in a chemical environment, Emory University scientists have opened the door to powerful new opportunities in drug delivery, environmental cleanup and synthetic biology. view more (2007-05-11)
Better together: Bacterial endosymbionts are essential for the reproduction of a fungus
Endosymbiotic relationships—in which one organism lives within another—are striking examples of mutualism, and can often significantly shape the biology of the participant species. view more (2007-04-06)
New petroleum-degrading bacteria found at Rancho La Brea Tar Pits in Los Angeles
Environmental scientists at UC Riverside have discovered that the Rancho La Brea tar pits in downtown Los Angeles, Calif., house hundreds of new species of bacteria with unusual properties, allowing the bacteria to survive and grow in heavy oil and natural asphalt. view more (2007-05-11)
U of M researchers discover key for converting waste to electricity
Researchers at the University of Minnesota studying bacteria capable of generating electricity have discovered that riboflavin (commonly known as vitamin B-2) is responsible for much of the energy produced by these organisms. view more (2008-03-04)
Reduced Risk from Appendix, Bowel or Birth
The risk of life threatening infection after a burst appendix, childbirth or bowel surgery has just been reduced, according to medical researchers who have discovered how a particularly dangerous bacterium fools our body's defences. The findings are presented today, Tuesday 8 April 2003, by Dr Sheila Patrick at the Society for General... view more... (2003-04-02)
Bacterial 'battle for survival' leads to new antibiotic
MIT biologists have provoked soil-dwelling bacteria into producing a new type of antibiotic by pitting them against another strain of bacteria in a battle for survival. view more (2008-02-27)
