redOrbit Staff & Wire Reports - Your Universe Online You might not need to throw out your tooth brush after recovering from a sore throat after all, according to a new study presented Saturday at the annual meeting of the Pediatric Academic Societies (PAS) in Washington DC. While some health care professionals tell patients – especially children – to replace their toothbrushes after suffering from a cold, the flu, or a case of strep throat, researchers from the University of...
A more rapid laboratory test for pregnant women to detect potentially deadly Group B strep (GBS) has been successful at identifying GBS colonization in six and a half hours, according to the results of a study from The University of Texas Health Science Center at Houston (UTHealth). The more rapid test could be helpful for the 13 percent of patients who experience pre-term labor before they are screened for GBS, which usually occurs between 35 and 37 weeks of gestation. The current...
The bacterium Streptococcus pneumoniae – which can cause pneumonia, meningitis, bacteremia and sepsis – likes to share its antibiotic-defeating weaponry with its neighbors. Individual cells can pass resistance genes to one another through a process called horizontal gene transfer, or by "transformation," the uptake of DNA from the environment. Now researchers report that they can interrupt the cascade of cellular events that allows S. pneumoniae to swap or suck up DNA. The new...
HARRISBURG, Pa., Sept. 21, 2012 /PRNewswire-USNewswire/ -- The Pennsylvania Department of Health is advising customers of Monarch Medspa in Harrisburg, King of Prussia and Philadelphia that they may have been exposed to Group A Streptococcus, or Group A Strep. The department is warning customers as a precautionary measure after learning that the chain's Maryland location closed on Sept. 19 due to Group A Strep exposure. Since the Maryland employees often work in the Pennsylvania...
Lawrence LeBlond for redOrbit.com - Your Universe Online Dentists have long encouraged the use of fluoride to prevent cavities and tooth decay. But several studies have also found that other things, such as lollipops, raisins, licorice root and gum, may also help in the fight against tooth decay. And now, a new study is suggesting that coconut oil could also combat tooth decay and could be used in a variety of dental care products. Scientists from the Athlone Institute of Technology in...
HUBBARD, Ohio, Aug. 1, 2012 /PRNewswire/ -- NanoLogix (OTC Markets: NNLX), a biotechnology innovator in the rapid detection and identification of live-threat bacteria, is featured today in the USA Today Group B Strep (GBS) Awareness Campaign titled Your guide to Group B Strep. The campaign featured in the USA Today News Section promotes public education on the dangers of GBS in newborns and highlights the latest testing methods to help prevent the disease. Research using...
A more accurate, faster diagnostic test for Group B Streptococcal infection in babies has been reported in the Journal of Medical Microbiology. The new test could allow better treatment and management of the disease and reduce the risk of mortality among newborns. Group B streptococcus (GBS) infections, caused by the bacterium Streptococcus agalactiae, are the most common cause of meningitis, septicaemia and pneumonia in newborns. In 2010 there were 506 cases of GBS infections in infants...
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...
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...

Streptococcus salivarius is a species of spherical, Gram-positive bacteria which colonize the mouth and upper respiratory tract of humans a few hours after birth, making further exposure to the bacteria harmless. The bacterium is an opportunistic pathogen which rarely makes its way into the bloodstream where it is associated with septicemia cases in people with neutropenia. It has different characteristics when exposed to different environmental nutrients. In the lab a SYTA plate is used...
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...
Streptococcus oralis is a Gram positive bacterium that grows characteristically in chains. On a Wilkins-Chalgren agar plate it will form slam white colonies. It is classified as a member of the streptococcus mitis group and is found in high numbers in the oral cavity. S. oralis produce neuraminidase and an IgA protease and cannot bind α-amylase.
Streptococcus mutans is a Gram-positive cocci, Facultative anaerobic bacterium commonly found in the human oral cavity and is a significant contributor to tooth decay. J Kilian Clarke first described the microbe in 1924. The first colonizers of the tooth surface are mainly Neisseria spp. and streptococci, including S. mutans. The pioneer species changes the local environmental conditions through growth and metabolism thus allowing more fastidious organisms to further colonize after them,...
