A potential vaccine against bacteria that cause serious gastric disorders including stomach cancer may be a step closer following a pioneering study by a University of Guelph chemist. In the first published study of its kind, a team led by Prof. Mario Monteiro, Department of Chemistry, found a carbohydrate-based antigen caused mice to develop antibodies against a common bacterium linked to gastric cancer. "This is the first jab at a sugar-based vaccine against Helicobacter pylori," said...

Children without previous iron deficiencies or anemia who remained infected with Helicobacter pylori (H. pylori) had significantly lower levels of iron compared to children who had the infection eradicated, according to researchers at The University of Texas Health Science Center at Houston (UTHealth). "Half of the world's population is infected with H. pylori and most of the individuals are asymptomatically infected, according to several surveys," said Victor Cardenas, M.D., Ph.D., lead...

Legionella experts give a stepwise approach to evaluate efficacy of disinfection methods. Authors recommend infection control practitioners lead environment of care team in choosing disinfection technologies; post-treatment followed by scheduled culturing for Legionella. Pittsburgh, PA (PRWEB) February 27, 2011 Legionnaires' disease outbreaks, caused by Legionella in hospital drinking water, can be prevented using the right disinfection methods. Too often hospitals make treatment...

First evidence of gene transfer from human host to bacterial pathogen offers new view of evolution, disease If a human cell and a bacterial cell met at a speed-dating event, they would never be expected to exchange phone numbers, much less genetic material. In more scientific terms, a direct transfer of DNA has never been recorded from humans to bacteria. Until now. Northwestern Medicine researchers have discovered the first evidence of a human DNA fragment in a bacterial genome "“ in...

40 percent to 60 percent of all cooling water systems tested contain Legionella--the bacterium that causes Legionnaires' disease. Nonchemical devices failed to control this bacterium in model cooling water towers according to an ASHRAE-funded study. Pittsburgh, PA (PRWEB) February 4, 2011 To avoid a potential health hazard, equipment operators, building owners, and engineers should monitor large cooling water systems that use nonchemical "green" devices to control Legionella, says Dr. Janet...

(Ivanhoe Newswire) -- Second-hand smoke increases risk of invasive meningococcal disease in children, according to a new study, where authors also found a possible association of second-hand smoke exposure with invasive pneumococcal disease and Haemophilus influenzae type b. The authors reviewed and analyzed published studies (30 case-control and 12 cross-sectional studies, mostly conducted in high income countries with good vaccination policies). They used the findings of all studies that...

Second-hand smoke increases risk of invasive meningococcal disease in children Children exposed to second-hand smoke are more likely to get invasive meningococcal disease than children who are not exposed, reports a study from Chien-Chang Lee at the Harvard School of Public Health (Boston, USA) and colleagues published in this week's PLoS Medicine. The authors also found a possible association of second-hand smoke exposure with invasive pneumococcal disease and Haemophilus influenzae type b....

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...
