Gonorrhea is evolving into a scourge resistant to most antibiotics, and urgent action is needed to combat this public health threat, states an editorial in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/site/embargo/cmaj111393.pdf. Gonorrhea, a sexually transmitted disease (STD) that causes pelvic inflammatory disease and urethritis, is evolving into multiresistant bacteria because most treatments are now ineffective. Japan reported the first example...

The discovery of a fundamental, previously unknown property of microbial nanowires in the bacterium Geobacter sulfurreducens that allows electron transport across long distances could revolutionize nanotechnology and bioelectronics, says a team of physicists and microbiologists at the University of Massachusetts Amherst. Their findings reported in the Aug. 7 advance online issue of Nature Nanotechnology may one day lead to cheaper, nontoxic nanomaterials for biosensors and solid state...

(Ivanhoe Newswire) -- In the largest study of its kind, researchers say different populations of people need different therapies to get rid of H. pylori, which is the primary cause of gastric cancer. According to the International Agency for Research on Cancer, stomach cancer was the fourth most common cancer and the second-leading cause of cancer death in the world in 2008. About 72 percent of new cases occur in developing countries. The current study, which was conducted at seven sites...

Largest study of its kind suggests different populations need different therapies to eradicate H. pylori, primary cause of gastric cancer Helicobacter pylori, the bacterium known to cause peptic ulcers, is also the primary cause of gastric cancer, which is a leading cancer killer globally. A large clinical trial at seven sites across Latin America has now found that a standard three-drug regimen for treating H. pylori is more effective, at least in the population studied, than either of two...

Purdue University biologists identified a new way in which bacteria hijack healthy cells during infection, which could provide a target for new antibiotics. Zhao-Qing Luo, the associate professor of biological sciences who led the study, said the team discovered a new enzyme used by the bacterium Legionella pneumophila - which causes Legionnaires' disease - to control its host cell in order to take up residence. "Legionnaires' disease is a severe form of pneumonia, and this finding could lead...

Scientists have found a new strain of gonorrhea in Japan that is resistant to all recommended antibiotics and could transform into a global public health threat. The new strain, or H041, cannot be killed by any currently recommended treatments for gonorrhea, which has left doctors with no other option than to try medicines so far untested against the disease. Magnus Unemo of the Swedish Reference Laboratory for Pathogenic Neisseria described the strain as both "alarming" and...

Infection with the gastric bacterium Helicobacter pylori provides reliable protection against allergy-induced asthma, immunologists from the University of Zurich have demonstrated in an animal model together with allergy specialists from the University Medical Center of the Johannes Gutenberg University Mainz. Their results published in the prestigious Journal of Clinical Investigation confirm the hypothesis recently put forward that the dramatic increase in allergic diseases in industrial...

Scientists have tested a predatory bacterium "“ Bdellovibrio "“ against Salmonella in the guts of live chickens. They found that it significantly reduced the numbers of Salmonella bacteria and, importantly, showed that Bdellovibrio are safe when ingested. The research was funded by the Biotechnology and Biological Sciences Research Council, carried out by Professor Liz Sockett's team at The University of Nottingham, with Dr Robert Atterbury and Professor Paul Barrow at the...

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...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
