It's a tragedy of war that innocent bystanders often get caught in the crossfire. But now scientists at the University of Pennsylvania and the University of Oxford have shown how a battle for survival at a microscopic level could leave humans as the unlikely victims. In work funded by the US Public Health Service and the Wellcome Trust, the researchers have found a possible explanation for why some bacteria turn nasty, even at great risk to their own survival. The body is home to a wide range...

A common bacteria found in many healthy adult females that can cause life-threatening infections when passed to newborns could be introduced to some women through frequent contact with cows, according to a research team led by a Michigan State University pediatrician. The recently published findings that Group B streptococcus could be a zoonotic disease - transmitted between different species - may have significant public health implications, said Dele Davies, chairperson of MSU's Department...

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...

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...

In a huge effort to test pregnant women for deadly bacteria that can be transmitted to their babies, it was found that many test results were false, leaving some infants untreated. A study found that the test missed more of the infections than usually expected. The mothers that tested positive for the Group B strep bacteria were given antibiotics during labor to decrease the chance of passing it to their infants. Group B Strep is a species of the normal flora of the female urogenital tract...

Britain's All-Party Parliamentary Group on Pneumococcal Disease Prevention officials say pneumococcal disease must be recognized as a global health issue. Between 700,000 and 1 million children under the age 5 die each year from pneumococcal disease and these child deaths are a largely preventable tragedy, the group says. A vaccine against pneumococcal disease exists and is being used in the Britain. The impact of this vaccine has been seen in England and Wales where there has been a 59...

Bad dental hygiene leads to bleeding gums which let in around 700 types of bacteria, it has emerged.These go straight to the bloodstream and are now known to be "independent factors" in causing heart disease no matter how fit and healthy the person is.Professor Howard Jenkinson from the University of Bristol, working with the Royal College of Surgeons made the discovery after examining how harmful bacteria interact with blood cells.He will explain the findings in detail today to members of...

PEOPLE who don't brush their teeth regularly increase their risk of a heart attack - even if they are fit and healthy, scientists said yesterday. Poor dental hygiene leads to bleeding gums which let in around 700 types of bacteria. These go straight to the bloodstream and are now known to be "independent factors" in causing heart disease. Professor Howard Jenkinson of the University of Bristol, working with the Royal College of Surgeons, made the discovery after examining how harmful...

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,...
