Newly identified strains of Chlamydia trachomatis could produce new diseases
A new study led by a scientist at Children's Hospital Oakland Research Institute (CHORI) is the first to conclude that Chlamydia trachomatis is evolving at a rate faster than scientists first thought or imagined. view more (2006-11-16)
New strategy for treating allergic disorders
Oral intake of allergens or auto-antigens via the lactic acid bacterium Lactococcus lactis might be a new strategy for treating various kinds of auto-immune and allergic disorders. view more (2007-08-01)
Anthrax bacterium's deadly secrets probed
New insights into why the bug that causes anthrax behaves in the unusual way that it does have come to light thanks to a development under the UK e-Science Programme. view more (2007-08-07)
Structure of key enzyme in plague bacterium found
Researchers at the National Institute of Standards and Technology (NIST) have solved the structure of a key enzyme from the bacterium responsible for plague, finding that it has a highly unusual configuration. The results may shed light both on how the bacterium kills and on fundamental cell signaling processes. view more (2006-08-21)
Salt increases ulcer-bug virulence
Scientists have identified yet another risk from a high-salt diet. High concentrations of salt in the stomach appear to induce gene activity in the ulcer-causing bacterium Helicobacter pylori, making it more virulent and increasing the likelihood of an infected person developing a severe gastric disease. view more (2007-05-23)
Plague proteome reveals proteins linked to infection
Recreating growth conditions in flea carriers and mammal hosts, Pacific Northwest National Laboratory scientists have uncovered 176 proteins and likely proteins in the plague-bacterium Yersinia pestis whose numbers rise and fall according to the disease's virulence. view more (2006-11-27)
The Role Of Phytochromes In Bacteria Revealed
A research team jointly involving the IRD, the CEA and the CNRS has very recently found phytochromes in a strain of nitrogen-fixing bacterium, Bradyrhizobium (1), symbiont on certain tropical leguminous plants (the Aeschynomene). Techniques of molecular biology, biophysics and biochemistry revealed that the newly-discovered phytochrome has an... view more... (2002-05-13)
Evolution mystery: Spider venom and bacteria share same toxin
Biology researchers at Lewis & Clark College and the University of Arizona have found evidence for an ancient transfer of a toxin between ancestors of two very dissimilar organisms-spiders and a bacterium. view more (2006-02-02)
Genome Sequencing Reveals a Key to Viable Ethanol Production
As the national push for alternative energy sources heats up, researchers at the University of Rochester have for the first time identified how genes responsible for biomass breakdown are turned on in a microorganism that produces valuable ethanol from materials like grass and cornstalks. view more (2007-03-05)
Ecosystem of vanishing lake yields valuable bacterium
In the salt flats near a slowly vanishing lake, a team of researchers have found never-before-seen bacterium that could clean up some of humanity's pollution. view more (2006-10-18)
UCF professor finds new way deadly food-borne bacteria spread
University of Central Florida Microbiology Professor Keith Ireton has uncovered a previously unknown mechanism that plays an important role in the spread of a deadly food-borne bacterium. view more (2009-09-21)
New bug to tackle pollution
A new, all-natural, pollutant-busting microbe has been discovered by scientists in Germany. Research published in the October 2003 issue of Microbiology, a Society for General Microbiology journal, describes a new strain of bacterium, which could be used in the near future to clean up polluted land. Over the years, many harsh and highly toxic... view more... (2003-10-10)
Researchers discover new disease-causing bacterium in patients with rare immune disorder
Scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), have discovered a new bacterium and determined that it can cause serious lymph node infections in patients with chronic granulomatous disease (CGD)-a rare immune disorder that leaves individuals susceptible to frequent... view more...

Study gives clues about how deadly bacterium gains foothold
How a potentially deadly bacterium that could be used as a bioterrorist tool eludes being killed by the human immune system is now better understood. view more (2006-12-20)
Stealth technology maintains fitness after sex
Pathogens can become superbugs without their even knowing it, research published today in Science shows. 'Stealth' plasmids-circular 'DNA parasites' of bacteria that can carry antibiotic-resistance genes-produce a protein that increases the chances of survival and spread of the antibiotic-resistant strain. view more (2007-01-12)
University of Georgia researchers discover cell-wall carbohydrate that is crucial to anthrax bacterium
A week after the 9/11 attacks in 2001, the letters began to arrive. Someone filled envelopes with a deadly strain of anthrax bacteria and mailed them to two U.S. senators and several offices of the news media. Five people died, and 17 others became infected. view more (2006-10-02)
Researchers push nature beyond its limits to create higher-density biofuels
For the first time, researchers at the UCLA Henry Samueli School of Engineering and Applied Science have successfully pushed nature beyond its limits by genetically modifying Escherichia coli, a bacterium often associated with food poisoning, to produce unusually long-chain alcohols essential in the creation of biofuels. view more (2008-12-19)
Pathogen that causes disease in cattle also associated with Crohn's disease
People with Crohn's disease (CD) are seven-fold more likely to have in their gut tissues the bacterium that causes a digestive-tract disease in cattle called Johne's disease. view more (2008-08-11)
Costly plant tumors are found by Cornell microbiologist to be result of soil bacterium 'smelling' and entering wound
How does a wound in certain plants like roses and grapevines develop into a tumor? The answer appears to lie in a common soil bacterium that is able to "smell" the wound and speed up the infection process. view more (2005-10-24)
Out of Africa-Bacteria, as well
When man made his way out of Africa some 60,000 years ago to populate the world, he was not alone: He was accompanied by the bacterium Helicobacter pylori, which causes gastritis in many people today. view more (2007-02-15)
