Scientists have discovered the tool that bacteria normally found in our mouths use to invade heart tissue, causing a dangerous and sometimes lethal infection of the heart known as endocarditis. The work raises the possibility of creating a screening tool "“ perhaps a swab of the cheek, or a spit test "“ to gauge a dental patient's vulnerability to the condition. The identification of the protein that allows Streptococcus mutans to gain a foothold in heart tissue is reported in the...

Bloodstream infections in newborns can lead to serious complications with substantial morbidity and mortality. What's more, the pathogens responsible for neonatal infections have changed over time. In recent years, however, antibiotic prophylaxis given to at-risk mothers has reduced the incidence of early-onset group B streptococcal infections among their babies. A new nationwide, multi-site study aimed at determining current early-onset sepsis rates among newborns, the pathogens involved,...

New pathogen contributes to severe early childhood caries Researchers at The Forsyth Institute have made a significant discovery about the nature of childhood dental disease. The scientific studies led by Anne Tanner, BDS, Ph.D., identified a new pathogen connected to severe early childhood caries (cavities). This bacterium, Scardovia wiggsiae, was present in the mouths of children with severe early childhood caries when other known pathogens such as Streptococcus mutans were not detected....

In a study to be presented today at the Society for Maternal-Fetal Medicine's (SMFM) annual meeting, The Pregnancy Meeting â“ž¢, in San Francisco, researchers will present findings that show that many women are having different test results for Group B streptococcus (GBS) between their routine third trimester screening and a rapid test performed at the time of labor. GBS early-onset sepsis is a leading cause of neonatal infection. GBS is a bacterium that normally...

Hydrocephalus in Ugandan children and other developing countries is seasonal, linked to farm animals and in part, caused by previous bacterial infection, according to an international team of researchers from Uganda and the United States, who believe that the best approach to this problem is prevention. "Hydrocephalus in infants in developing countries is a grand medical mystery," said Steven Schiff, the Brush Chair professor of engineering and director, Penn State Center for Neural...

An international team led by a University of Cincinnati (UC) researcher has shown how a bacterial community evolves to survive hostile host defenses in the body. The team, led by Malak Kotb, PhD, chair of UC's of molecular genetics, biochemistry and microbiology department, analyzed the evolution over time of the community structure of Group A streptococcus (also known as GAS or Strep A), a bacterium often found in the throat or on the skin. It can cause many human diseases, ranging from...

WHAT: Scientists supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have completed a Phase II clinical study that indicates a vaccine to prevent Group B Streptococcus (GBS) infection is possible. GBS is the most common cause of sepsis and meningitis in newborns in the United States, according to the Centers for Disease Control and Prevention (CDC). It can also cause severe illness in pregnant women, the elderly and adults...

British and European researchers say Wolfgang Amadeus Mozart likely died from a strep throat epidemic that appeared to have occurred in Vienna in 1791. Many theories, including mercury poisoning, syphilis, trichinosis and other conditions, have been suggested over the years as the cause of Mozart's death but an epidemiological analysis published in the Aug. 18 issue of The Annals of Internal Medicine says the young composer was likely a victim of an epidemic streptococcal infection, The New...

A new Dutch study finds that complications of strep throat may have been behind the sudden death at age 35 of Wolfgang Amadeus Mozart in 1791. Various theories for Mozart's cause of death have surfaced over the years since his sudden passing at the age of 35, including suspicions he was intentionally poisoned or had suffered from rheumatic fever or trichinosis, a parasitic disease caused by eating undercooked pork. His death certificate recorded hitziges Frieselfieber, or "heated miliary...

SUNNYVALE, Calif., June 24 /PRNewswire-FirstCall/ -- Cepheid (Nasdaq: CPHD) today noted that a new article, Evaluation of Universal Antenatal Screening for Group B Streptococcus, published in the June 2009 issue of the New England Journal of Medicine concluded that rapid, PCR-based testing at the time of admission for delivery may improve the accuracy of Group B streptococcal (GBS) screening over the normal antepartum testing done at 35-37 weeks of gestation. GBS disease is one of the most...

Streptococcus pyogenes is a spherical, Gram-positive bacterium is the cause of Group A streptococcal infections. It displays streptococcal group A antigen on its cell wall. When it is cultured on blood agar plates it produces large zones of beta-hemolysis. They are catalase-negative and in ideal conditions it has an incubation period of about 1-3 days. It is an infrequent part of the skin flora. It is the cause of many important human diseases, ranging from mild superficial skin infections...

Streptococcus pneumoniae, or pneumococcus, is Gram-positive, alpha-hemolytic, bile-soluble aerotolerant, anaerobic member of the genus Streptococcus. It was recognized as a major cause of pneumonia in the late 19th century and is thus the subject of many humoral immunity studies. It causes many other types of pneumococcal infections other than pneumonia including acute sinusitis, otitis media, meningitis, bacteremia, sepsis, septic arthritis, peritonitis, cellulites, and brain abscess. It...

Enterococcus faecalis "“ formerly classified as part of the Group D Streptococcus system "“ is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans and other mammals. It is one of the main constituents of some probiotic food supplements. E. faecalis can cause life-threatening infections in humans. It is frequently found in root canal-treated teeth in prevalence values ranging from 30% to 90% of the cases. It is a non-motile, facultatively anaerobic...
