Bacteria that cause tooth decay able to survive without important biochemical pathway
Leave it to the bacteria that cause tooth decay to be able to live without something all cells were thought to require. view more (2005-12-14)
Report focuses on the role good microbes play in future medicine
Not all bacteria are bad. In fact, beneficial microbes could represent the future of medicine, with the potential to treat a variety of diseases in humans and animals from diarrhea and eczema to gum disease and autoimmune disorders. view more (2006-06-09)
Deep in the ocean, a clam that acts like a plant
How does life survive in the black depths of the ocean? At the surface, sunlight allows green plants to "fix" carbon from the air to build their bodies. view more (2007-02-21)
Malaria researchers identify new mosquito virus
Researchers at the Johns Hopkins Bloomberg School of Public Health's Malaria Research Institute have identified a previously unknown virus that is infectious to Anopheles gambiae-the mosquito primarily responsible for transmitting malaria. view more (2008-08-22)
UCSD team unmasks family of immune system invaders
Like a family of petty criminals gone wrong, researchers at the University of California, San Diego (UCSD) were surprised to find that bacterial pathogens found in a number of troublesome diseases are actually related. view more (2006-01-13)
Researchers uncover E. coli's defense mechanism
The pathogenic forms of E. coli and Salmonella are usually transmitted to humans through undercooked meat, unwashed vegetables and cross contamination from surfaces on which these foods were prepared. view more (2005-09-29)
Edible food wrap kills deadly E. coli bacteria
Researchers have improved upon an edible coating for fresh fruits and vegetables by enabling it to kill deadly E. coli bacteria while also providing a flavor-boost to food. view more (2006-11-17)
Researchers use dirt to stay one step ahead of antibiotic resistance
Dirt may be a key to how bacteria that infect humans develop a resistance to antibiotic drugs. view more (2006-01-20)
Antibiotics do not prevent recurrent myocardial infarcts in subjects with periodontitis
Periodontitis, an infection of the gingiva and tooth-supporting tissues, may influence the effectiveness of antibiotics used for the prevention of recurrent cardiovascular events. view more (2006-01-05)
Figuring out function from bacteria's bewildering forms
The constellation of shapes and sizes among bacteria is as remarkable as it is mysterious. Why should Spirochaeta halophila resemble a bedspring coil, Stella a star and Clostridium cocleatum a partly eaten donut? No one really knows. view more (2006-07-19)
A molecule impedes the destruction of the 'Brucella' bacteria
Research carried out with the participation of the University of Navarra has shown how a determinate molecule helps an important pathogen, Brucella abortus, escape destruction within the cells charged with eliminating infectious agents (macrophages). view more (2005-06-15)
Researcher hits bulls-eye for antibiotic target
A Purdue University researcher has opened the door for possible antibiotic treatments for a variety of diseases by determining the structure of a protein that controls the starvation response of E. coli. view more (2006-08-23)
Emerging staph strains found to be increasingly deadly and deceptive
A study of how the immune system reacts to strains of antibiotic-resistant Staphylococcus aureus bacteria-emerging strains that sicken otherwise healthy people, or so-called "community-acquired" infections-has shown for the first time that these strains are more deadly and better at evading human immune defenses than more common S.... view more...

Yale biologists 'trick' viruses into extinction
While human changes to the environment cause conservation biologists to worry about species extinction, Yale biologists are reversing the logic by trying to trap viruses in habitats that force their extinction, according to a report in Ecology Letters. view more (2007-02-13)
First human trial of antibacterial contact lens
Biotechnology company Biosignal Ltd and the Institute for Eye Research have received ethics approval for the first human clinical trial of an antibacterial extended-wear contact lens. view more (2006-06-29)
First link of oral bacteria and preterm birth found in human
A 37-year-old-mother, who gave birth to a low-weight preemie at 24 weeks, exhibited the first-found link in a human between bacteria found in the mouth and the amniotic fluid of a woman in preterm labor. view more (2006-04-06)
Rochester Scientists Develop Fast-Working Biosensor
University of Rochester Medical Center scientists have demonstrated a new technology that accurately and rapidly detects the meat-spoiling and sometimes dangerous E. coli bacteria. view more (2006-02-24)
Insects cultivate 'antibiotic-producing bacteria' in their antennae
Bacteria live in, on and around us and other organisms with sometimes very beneficial results. For the first time scientists have shown that one species of insect deliberately cultivates bacteria in its antennae in order to protect their larvae from fungal attack. view more (2007-04-02)
Cranberries contain possible anti-caries/anti-plaque agents
Scientists have discovered that the humble cranberry harbors several anti-oxidants (flavonoids) that show the ability to counteract the damaging effects of the bacterium Streptococcus mutans, which causes dental caries (tooth decay). view more (2006-06-29)
Penn study finds a new role for RNA in human immune response
Researchers at the University of Pennsylvania School of Medicine have published the first study to test the role of RNA chemical modifications on immunity. view more (2005-08-24)
