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...
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 by...
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...
Mothers of Children Personally Affected By Meningococcal Meningitis Reach Out to Other Families at www.nmaus.org/panel MARIETTA, Ga., May 11 /PRNewswire/ -- Lori Buher and Marybeth Leeber each watched her child ravaged by meningococcal disease (also known as bacterial meningitis) -- enduring comas, painful skin grafts, organ transplants and multiple limb amputations. Jane Hession and Kathy Huddleson both lost an otherwise healthy child to the disease within hours of their first symptoms....
HOUSTON, April 24 /PRNewswire-USNewswire/ -- Meningitis Angels, a national organization, will recognize World Meningitis Day (WMD) by enjoining Angels from around the world. The organization was founded in memory of Ryan Milley, the only child of Bob and Frankie Milley, and since has grown to include over 600 families in the U.S. and some 30+ abroad. Frankie Milley serves as the national executive director and also works very hard as a children's health and immunization advocate....
According to researchers, a test vaccine against Campylobacter jejuni, a major cause of traveler's diarrhea, provided protection against infection in mice and monkeys and may ultimately have human application.Also, C. jejuni not only causes diarrhea, but is associated with a number of "important sequelae," including inflammatory bowel disease, Dr. Patricia Guerry, senior investigator, told Reuters Health. There are no licensed vaccines for C. jejuni currently available. Guerry...
Antimicrobial Developer Adds New Measurement Tool to Assist Processing Plants. SHREVEPORT, La., March 25 /PRNewswire/ -- Since 2003, SteriFx Inc. and its FreshFx antimicrobial solutions have proven to be effective on the poultry processing line against Campylobacter jejuni (Campy), as well as Salmonella, E. coli, and Listeria. Now SteriFx can provide plant management another tool to help control Campylobacter by pre-screening birds for their current load of Campy at various points...

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...
