By Maggie Fox, Health and Science Correspondent WASHINGTON -- 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. All but one of the people killed by Streptococcus suis in July and August 2005 in China died of streptococcal toxic shock syndrome, they said. This severe type of immune reaction had never been seen in S. suis infections. Anyone who is diagnosed with toxic shock syndrome and who has...

LONDON (Reuters) - A new vaccine from GlaxoSmithKline Plc could help to reduce middle ear infection, a common problem in toddlers, scientists said on Friday. Researchers at the University of Defense in Hradec Kralove in the Czech Republic said the vaccine they tested against middle ear infection, or otitis media, reduced cases of the illness by about 30 percent in babies who had been vaccinated in the first six months of life. "We found a reduction in ear, nose and throat...

NEW YORK (Reuters Health) - Black women, health care workers, and overweight women are at increased risk for carrying group B streptococcus (GBS) during pregnancy, new research suggests. GBS is a microbe that can live in or "colonize" the birth canal and then be passed onto the infant during birth, resulting in a potentially life-threatening infection. Better knowledge of factors that increase the risk of GBS colonization in pregnancy could help efforts to prevent or treat the infection and...

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. The 61-year-old man had traveled to Guangzhou, the capital of China's neighboring Guangdong province, in September and became ill on October 4 with back pain and lower limb weakness. He was admitted to hospital and is in stable condition, the Health...

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. Researchers are studying a vaccine that may one day eliminate that risk. "If we could give a vaccine to prevent women from harboring group B streptococcus in the vagina, then babies are not going to get it," says Dr. Daron Ferris, family medicine physician at the Medical College of Georgia and a principal investigator on a...

By Amy Norton NEW YORK (Reuters Health) - Some infants delivered by cesarean section may have a higher risk of developing cavities later in life, a new study suggests. Researchers found that among young children who harbored a particular cavity-causing bacterium in their mouths, those who were delivered by C-section acquired the infection one year earlier, on average, than those delivered vaginally. Mothers appeared to be the main source of transmission of the bacterium, known as...

BEIJING (Reuters) - China's far south is on high alert after one person was killed and three were infected by a pig-borne disease that has killed nearly 40 in the southwest, suggesting dangerous meat is being traded across the country. The latest victim of the disease, caused by the Streptococcus suis bacterium, had handled infected pork, Xinhua news agency said on Tuesday. The three infected patients, all butchers, also likely had contact with tainted meat. "The Shenzhen patient was...

HONG KONG (Reuters) - A butcher at one of Hong Kong's leading supermarket chains has contracted a pig-borne disease that has infected over 200 people and killed 39 in southwest China, the city's Health Department said. The 44-year-old man, who was not identified, is the fourth person to become infected with the Streptococcus suis bacteria in Hong Kong since the outbreak in China was first reported in June, and the ninth person to catch the disease in the city this year. The report...

HONG KONG (Reuters) - A 78-year-old woman in Hong Kong has contracted a pig-borne disease that has killed 39 people in southwest China in recent weeks. The case is the third in Hong Kong since an outbreak of the disease, caused by the Streptococcus suis bacteria, began in China's Sichuan province around June. None of the three people had traveled recently outside Hong Kong. A government spokesman said the woman was in stable condition in hospital. She developed fever and pain in her...

Millions of bacteria live within the recesses of our noses and upper respiratory tracts, waiting for a chance to infiltrate and infect. But long before these bacteria break through our immune defenses, they must first compete against other bacterial species to colonize the mucus-lined surfaces of our noses. Competition between two common nose bacteria involves some interesting trickery, according to a new study in PLoS Pathogens. "We're looking at how bacteria use their host, and we've found...

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,...
