Latest Proteobacteria Stories
The genetic make-up of pathogenic bacteria and their harmless cousins is much more similar than previously thought, UA microbiologists find.
Researchers have discovered a mechanism by which Helicobacter pylori, the only known cancer-causing bacterium, disables a tumor suppressor protein in host cells.
When it infects the lungs, the Legionnaireâ€™s bacterium Legionella pneumophila causes acute pneumonia.
Researchers have identified cells in the immune system that react to the stomach ulcer bacterium Helicobacter pylori, one of the risk factors for the development of stomach cancer.
Sampling of pigeons captured on the streets of Madrid has revealed the bacterial pathogens they carry.
An international team of researchers led by scientists at the Virginia Bioinformatics Institute (VBI) at Virginia Tech have sequenced the genome of an Amerindian strain of the gastric bug Helicobacter pylori, confirming the out-of-Africa migration of this bacterial stowaway to the New World.
DALLAS, June 15 /PRNewswire/ -- RealTime Laboratories, LLC announced today significant new findings regarding pervasive bacterial presence unique to contaminated drywall.
CHICAGO, May 28 /PRNewswire-FirstCall/ -- Advanced Life Sciences Holdings, Inc.
SEATTLE, May 28 /PRNewswire/ -- The bacterium Helicobacter pylori, which lives in the human stomach and is associated with ulcers and gastric cancer, is shaped like a corkscrew, or helix.
Unlocking the keys to H. pylori's helical structure may lead to better antibiotic drugs for diseases from ulcers and stomach cancer to diarrhea and cholera.
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...
