The father of a 14-year-old boy says doctors are desperately trying to save his son from bacteria the teen likely contracted at a North Carolina lake. Brian McKinney told WTVD-TV, Durham, N.C., Wednesday a common bacteria has already forced doctors to remove part of his son Matthew's nose and five of his teeth. It's not every day a doctor says, 'Your son's dying. We're going to try to save his life,' said McKinney, whose son has also lost part of his palate due to the infection. McKinney said...

The stomach ulcer bacterium Helicobacter pylori is not transmitted through drinking water as previously thought, but rather through vomit and possibly faeces. This is shown in a thesis at the Sahlgrenska Academy. It is therefore possible to prevent the spread of the bacterium in developing countries through some fairly simple measures.'Taking some cheap but powerful measures may prevent the spread of the bacterium. It could be enough to isolate vomiting patients especially from small children...

 Current research suggests that levels of gastrin play a key role in the development of Helicobacter-induced stomach cancer. The related report by Takaishi et al, "Gastrin is an essential cofactor for Helicobacter-associated gastric corpus carcinogenesis in C57BL/6 mice," appears in the July 2009 issue of The American Journal of Pathology.More than 50% of the world's population is infected with Helicobacter pylori, which causes chronic inflammation of the stomach lining and is strongly...

U.S. researchers say they can prevent ear infections in animals with new vaccines rubbed on the skin. The experimental vaccines were applied in a new way -- a method called transcutaneous vaccination -- which involved placing a droplet of each vaccine onto the ear and rubbing it into the skin Previous work in our lab showed that after immunization by injection, each of the three vaccine candidates prevented experimental ear infections caused by NTHi, study researcher Laura Novotny of the...

U.S. medical researchers say they've discovered popular glutamine supplements show promise in the treatment of stomach ulcers. Since it's been known Helicobacter pylori bacteria are responsible for stomach ulcers, antibiotics have become the primary therapy for such conditions. But scientists say bacteria are growing increasingly resistant to antibiotics. In the new study led by scientists at Beth Israel Deaconess Medical Center in Boston and the Massachusetts Institute of Technology,...

British medical scientists say they have discovered how meningococcal bacteria break through the body's natural defense system to attack the brain. University of Nottingham researchers said their discovery could lead to better treatment and vaccines. The scientists said it can take just hours after symptoms appear for someone to die from bacterial meningitis, which in childhood is nearly exclusively caused by the respiratory tract pathogens Streptococcus pneumoniae, Neisseria meningitidis and...

Amino acid helps offset stomach damage caused by H. pylori bacteria; animal study suggests popular supplement could also reduce risk of gastric cancersNearly 20 years ago, it was discovered that bacteria known as Helicobacter pylori were responsible for stomach ulcers. Since then, antibiotics have become the primary therapy used to combat the H. pylori infection, which affects approximately six percent of the world population and is also a primary cause of stomach cancer. But today the...

It can take just hours after the symptoms appear for someone to die from bacterial meningitis. Now, after years of research, experts at The University of Nottingham have finally discovered how the deadly meningococcal bacteria is able to break through the body's natural defense mechanism and attack the brain. The discovery could lead to better treatment and vaccines for meningitis and could save the lives of hundreds of children. Bacterial meningitis in childhood is almost exclusively caused...

A U.K. agency says it has determined retail chicken is the single largest source of campylobacter food poisoning in Scotland. The Food Standards Agency said it investigated the sources of bacterial infection to assist in the development of strategies to reduce food poisoning incidents. Scientists led by Ken Forbes of the Department of Medical Microbiology at the University of Aberdeen said they used a molecular typing method to compare campylobacter strain types from clinical cases with those...

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...
