Bacterial meningitis is an infection of the meninges, the protective membrane that covers the spinal cord and brain. Children, elderly patients and immunocompromized patients are at a higher risk for the development of severe bacterial meningitis. Recently, researchers at the University of Adelaide in Australia sought to identify new vaccine targets in Streptococcus pneumoniae, which is the most common cause of bacterial meningitis in the world. Led by Dr. Abiodun Ogunniyi, the research team...

Data from 2 new studies presented at the World Congress of Cardiology organized by the World Heart Federation Widespread screening of children in poorer countries is now being studied and is resulting in the diagnosis of rheumatic heart disease (RHD) in patients that would likely have gone undetected under normal circumstances, according to two new studies carried out in Fiji and Uganda presented today at the World Congress of Cardiology. Coordinated screening and control programs can...

Preliminary data from the REMEDY study presented at the World Congress of Cardiology organized by the World Heart Federation Rheumatic heart disease (RHD) is significantly under-treated in Africa and India according to the preliminary findings of a new global study presented today at the World Congress of Cardiology. Across the African and Indian regions included in the study it was revealed that patients are not receiving the surgery they need, secondary prevention with penicillin - to...

Oral bacteria that escape into the bloodstream are able to cause blood clots and trigger life-threatening endocarditis. Further research could lead to new drugs to tackle infective heart disease, say scientists presenting their work at the Society for General Microbiology's Spring Conference in Dublin this week. Streptococcus gordonii is a normal inhabitant of the mouth and contributes to plaque that forms on the surface of teeth. If these bacteria enter into the blood stream through...

Scientists from the Schepens Eye Research Institute, a subsidiary of Mass. Eye and Ear and affiliate of Harvard Medical School, have found for the first time that a bacterial pathogen can literally mow down protective molecules, known as mucins, on mucus membranes to enter and infect a part of the body. Their landmark study, published in the March 7, 2012 PLoS ONE, describes how they discovered that an "epidemic" strain of the bacterium Streptococcus pneumoniae, which causes conjunctivitis,...

A novel bacterium, thought to be a common inhabitant of the oral cavity, has the potential to cause serious disease if it enters the bloodstream, according to a study in the International Journal of Systematic and Evolutionary Microbiology. Its identification will allow scientists to work out how it causes disease and evaluate the risk that it poses. The bacterium was identified by researchers at the Institute of Medical Microbiology of the University of Zurich and has been named...

Researchers have discovered a promising alternative to common antibiotics used to fight the bacteria that causes strep throat. In an article published in the Proceedings of the National Academy of Sciences, the scientists discussed how their discovery could fight the infection with a reduced risk of antibiotic resistance. By screening tens of thousands of small molecules, the team from the University of Missouri and University of Michigan identified a class of chemical compounds that...

A study led by Russell R. Russo, MD, a third-year Orthopaedic Surgery resident at LSU Health Sciences Center New Orleans School of Medicine, has identified a new source of life-threatening necrotizing fasciitis — "bath salts." The study, describing the first known case of necrotizing fasciitis from an intramuscular injection of the street drug known as "bath salts," is published in the January 2012 issue of Orthopedics, now available online. Necrotizing fasciitis is an orthopedic...

Two strains of Streptococcus bacteria, that have evolved to cause potentially fatal infections in either horses or humans, use the same box of tricks to cause disease. Exploiting their genetic similarities could lead to novel vaccines for both man and beast, according to a review published in the Journal of Medical Microbiology. Streptococcus pyogenes is responsible for tonsillitis, scarlet fever and toxic shock syndrome in humans. Its equine equivalent, Streptococcus equi, infects horses to...

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...
