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.
"Flesh-eating" or "Strep" bacteria are able to survive and spread in the body by degrading a key immune defense molecule, according to researchers at the University of California, San Diego, School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences.
Research led by the University of Warwick has uncovered exactly how the bacterium Streptococcus pneumoniae has become resistant to the antibiotic penicillin. The same research could also open up MRSA to attack by penicillin and help create a library of designer antibiotics to use against a range of other dangerous bacteria.
By Lisa Redmond, The Sun, Lowell, Mass. Aug. 17--A 35-year-old Ayer woman who gave birth to a healthy baby last week at Emerson Hospital in Concord has been transferred to Massachusetts General Hospital in Boston after being diagnosed with a rare flesh-eating disease.
A dangerous infection that pigs can pass to people took an unusually fatal form last year and killed 38 people, Chinese scientists reported on Monday.
LONDON (Reuters) - A new vaccine from GlaxoSmithKline Plc could help to reduce middle ear infection, a common problem in toddlers, scientists said on Friday.
Black women, health care workers, and overweight women are at increased risk for carrying group B streptococcus (GBS) during pregnancy, new research suggests.
HONG KONG (Reuters) - Hong Kong has reported its 13th human case this year of the pig-borne disease Streptococcus suis, a retiree who the health department said likely came into contact with infected raw pork while cooking at home.
Common bacteria that live harmlessly in the gastrointestinal tract and vagina of 25 percent of women can become lethal if a newborn gets exposed to them during birth.
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 Î±-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,...
