Scientists are reporting discovery of a much sought after crack in the armor of a common microbe that infects the stomachs of one-sixth of the world's population, causing stomach ulcers and other diseases. They identified a group of substances that block a key chemical pathway that the bacteria need for survival. Their study, which could lead to new, more effective antibiotics to fight these hard-to-treat microbes, is scheduled for the October 16 issue of ACS Chemical Biology, a monthly...

By adapting a single protein on the surface of the bacterium Caulobacter crescentus, researchers at the University of British Columbia have turned it into a protein production factory, making useful proteins that can act as vaccines and drugs. Dr. John Smit presented the findings at the Society for General Microbiology's meeting at Heriot-Watt University, Edinburgh, today (7 September). C. crescentus is a harmless bacterium that has a single protein layer on its surface. Dr Smit's team...

U.S. researchers, in studies involving mice, link a diarrhea-causing bacteria to a type of colon cancer. Study leader Dr. Cynthia Sears of The John Hopkins University School of Medicine says strains of this common bacteria -- Bacteroides fragilis -- sometimes trick immune system cells into allowing colon tissue to be continuously inflamed and may set the stage for malignancy. This could be the H. pylori of colon cancer, Sears says in a statement. H.pylori is a bacteria known to cause stomach...

Scientists from the Department of Biological Sciences and the Virginia Bioinformatics Institute (VBI) at Virginia Tech have developed a quantitative, mathematical model of DNA replication and cell division for the bacterium Caulobacter crescentus. C. crescentus, an alpha-proteobacterium that inhabits freshwater, seawater and soils, is an ideal organism for genetic and computational biology studies due to the wealth of molecular information that has been accumulated by researchers. It also...

Four patients at an Arizona hospital were incorrectly diagnosed with Legionnaires' disease last year because of un-sterilized ice, health officials said. The Centers for Disease Control and Prevention's Mortality and Morbidity Weekly Report said unsterilized ice for bronchoscopies -- inspection inside the lungs using a flexible tube and video camera -- can transmit Legionella bacteria, which may lead to incorrect diagnosis. Investigators said ice from two machines that were connected to the...

HOUSTON, Aug. 13 /PRNewswire-USNewswire/ -- Dressed in camouflage and armed with the facts of disease and prevention, Meningitis Teen Angels (MA) launched their new national meningitis pre-teen and teen back-to-school campaign today: Stomping Out Meningitis. Meningitis Angels was founded in memory of Ryan Milley, who died at the age of 18 from meningococcemia, a severe infection of the bloodstream caused by the bacteria Neisseria meningitidis. This is the same bacteria which causes...

A team of researchers from Boston University, Harvard Medical School and Massachusetts Institute of Technology recently made a discovery that changes a long held paradigm about how bacteria move through soft gels. They showed that the bacterium that causes human stomach ulcers uses a clever biochemical strategy to alter the physical properties of its environment, allowing it to move and survive and further colonize its host.The Proceedings of the National Academy of Sciences reports the...

The unique association between microorganisms and their hosts, whether insects, plants, or mammals, provides a fascinating view into how microbial symbionts adapt to changing biological environments. Insights into the diversity and complexity of symbiotic relationships are the focus of the current special issue of DNA and Cell Biology, a peer-reviewed journal published by Mary Ann Liebert, Inc. The issue is available free online at www.liebertpub.com/dna "Symbiosis is one of the most...

NEW YORK, July 22 /PRNewswire-USNewswire/ -- When a dog or cat bites, an infection can follow. "Wounds that are most likely to become infected are those on the face and hands or when people wait more than eight hours before seeking medical attention," said Dr. Kate Stenske, a clinical assistant professor at Kansas State University's College of Veterinary Medicine. "If you are bitten, first wash the wound thoroughly with soap and water, and then call your physician right away." Stenske...

Salmonella enterica is a subspecies of Salmonella enterica, the rod shaped, flagellated, aerobic, Gram-negative bacterium. It is a member of the genus Salmonella and many of the pathogenic serovars of the S. enterica species are in this subspecies. Serovars can be designated fully or in a shortened form. The genus, Salmonella, is on the short form lists which are followed by the capitalized and non-italicized serovar. Each serovar can have many strains as well, which allows for a rapid...

Neisseria meningitidis is a heterotrophic gram-negative diplococcal bacterium best known for its role in meningitis and other forms of meningococcal disease such as meningococcemia. It is a major cause of morbidity and mortality during childhood in industrialized countries and is responsible for epidemics in Africa and in Asia. In the US there are approximately 2500 to 3500 cases of N. meningitides infections. Children under 5 are at a higher risk as well as people in the sub-Saharan...

Helicobacter pylori is a Gram-negative, microaerophilic bacterium that can inhabit various areas of the stomach, particularly the antrum. It causes low-level inflammation of the stomach lining and is linked to gastric ulcers and stomach cancer. Out of those infected, 80%, are asymptomatic. It was initially named Campyloacter pyloridis and then renamed C. pylori to correct the Latin grammar error. It was later placed in the genus, Helicobacter. Over 50% of the population has H. pylori in...

Haemophilus influenzae is a Gram-negative, rod-shaped bacterium first described in 1892 by Richard Pfeiffer during an influenza pandemic. It is generally aerobic but can grow as a facultative anaerobe. H. influenzae was mistakenly considered to be the cause of influenza until 1933 when the flu virology became apparent. It was the first free-living organism to have its entire genome sequenced. The project was completed and published in 1995. Two major categories were defined: the...

Haemophilus ducreyi is a fastidious gram-negative coccobacillus causing the sexually transmitted disease chancroid, a major cause of genital ulceration in developing countries characterized by painful sores on the genitalia. Early symptoms are dark and light green shears in excrement. Chancroid starts as an erythematous popular lesion that breaks down into a painful bleeding ulcer. It can be cultured on chocolate agar. It is an opportunistic microorganism that infects through the...
