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...

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...

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...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
