New Bacteria Test Could Improve Quality of Fruit and Vegetable Juice
Increasingly, consumer products, especially food and beverage products, are being scrutinized for better quality. view more (2007-05-10)
Staph vaccine shows promise in mouse study
By combining four proteins of Staphylococcus aureus that individually generated the strongest immune response in mice, scientists have created a vaccine that significantly protects the animals from diverse strains of the bacterium that cause disease in humans. view more (2006-10-31)
Gene exchange common among sex-manipulating bacteria
Certain bacteria have learned to manipulate the proportion of females and males in insect populations. Now Uppsala University researchers have mapped the entire genome of a bacterium that infects a close relative of the fruit fly. view more (2009-03-26)
Advance in cholera bacteria points to new treatment and vaccine
Opening a new door to an effective vaccine and therapy for a disease that strikes thousands annually, researchers at Dartmouth Medical School discovered that the bacteria that causes the intestinal disease Cholera spreads in the environment in much the same way it infects humans. view more (2005-12-08)
Monash scientists debug superbug
An international team of scientists, led by Monash University researchers, has uncovered the workings of a superbug that kills elderly hospital patients worldwide - a discovery that has the potential to save lives and health care systems billions of dollars each year. view more (2009-03-02)
Fast way of spotting multidrug resistant bacteria could help stop outbreaks in hospitals
A type of bacterium widely found on our skin and in the environment has now become a major threat in hospitals where it can cause serious infections, such as pneumonia in severely ill patients. view more (2007-11-28)
Discovery of Tuberculosis Bacterium Enzyme Paves Way for New TB Drugs
A team of University of Maryland scientists has paved the way for the development of new drug therapies to combat active and asymptomatic (latent) tuberculosis infections by characterizing the unique structure and mechanism of an enzyme in M. tuberculosis, the bacterium that causes the disease. Assistant Professor of Chemistry and Biochemistry... view more... (2009-03-30)
Poultry probiotics - Easter discovery for UK chicks
UK scientists have discovered a new way to combat food poisoning, by targeting it in living animals using beneficial bacteria. Probiotics provide fresh hope for destroying food poisoning bacteria in poultry before it enters the food chain. Scientists at the Institute of Food Research (IFR) have discovered that the probiotic Lactobacillus johnsonii... view more... (2004-04-07)
When intestinal bacteria go surfing
The bacterium Escherichia coli is part of the healthy human intestinal flora. However, E. coli also has pathogenic relatives that trigger diarrhea illnesses: enterohemorrhagic E.coli bacteria. During the course of an infection they infest the intestinal mucosa, causing injury in the process, in contrast to benign bacteria. view more (2009-03-19)
Mosquito parasite may help fight dengue fever
Dengue fever is a terrible viral disease blighting many of the world's tropical regions. Carried by mosquitoes, such as Aedes aegypti, 40% of the world's population is believed to be at risk from the infection. view more (2009-05-01)
Modified mushrooms may yield human drugs
Mushrooms might serve as biofactories for the production of various beneficial human drugs, according to plant pathologists who have inserted new genes into mushrooms. view more (2007-06-25)
A new, dechlorinating bacterium
Several industrial activities of the previous decades resulted in serious contamination of groundwater. For instance, polyvinyl chloride (PVC) production and related activities cause annual underground releases of 137 tonnes of 1,2-dichloroethane (1,2-DCA) in the USA (1988-1999). The latter molecule has an environmental half-life of about 50... view more... (2003-04-22)
"Harmless" Bacterium Found to Cause 10 Percent of COPD Flare-Ups
A ubiquitous bacterial strain thought to be uninvolved in chronic obstructive pulmonary disease (COPD) in fact is responsible for 2-4 million flare-ups of the condition that occur annually in the United States, researchers from the University at Buffalo have shown. view more (2005-07-21)
Insects implicated in the evolution of new human infectious diseases
Insects and other invertebrates are the arena for the evolution of new infectious diseases in humans, new research shows. view more (2004-10-25)
Tiny shock absorbers help bacteria stick around inside the body
Bacteria have hair-like protrusions with a sticky protein on the tip that lets them cling to surfaces. The coiled, bungee cord-like structure of the protrusions helps the bacteria hang on tightly, even under rough fluid flow inside the body. view more (2006-08-30)
Helicobacter pylori can multiply in autophagic vesicles
Helicobacter pylori, a Gram-negative, flagellated, microaerophilic bacterium, can selectively colonize in the human stomach. Its infection is widespread throughout the world, and is present in about 50% of the global human population with 80% in developing countries and 20-50% in industrialized countries. view more (2009-01-28)
Genetic adaptations key to microbe's survival in challenging environment
The genome of a marine bacterium living 2,500 meters below the ocean's surface is providing clues to how life adapts in extreme thermal and chemical gradients, according to an article published Feb. 6 in the journal PLoS Genetics, an open-access publication published by the Public Library of Science. view more (2009-02-11)
Researchers develop new ultrasensitive assay to detect most poisonous substance known
Scientists at City of Hope and the California Department of Public Health have developed a new ultrasensitive assay to detect botulinum neurotoxin. view more (2008-05-01)
Beetles get by with a little help from their friends
Humans living in communities often rely on friends to help get what they need and, according to researchers in the lab of Cameron Currie at the University of Wisconsin-Madison, many microbes, plants and animals benefit from 'friendly' associations too. view more (2008-10-03)
Single gene lets bacteria jump from host to host
All life - plants, animals, people - depends on peaceful coexistence with a swarm of microbial life that performs vital services from helping to convert food to energy to protection from disease. view more (2009-02-02)
