Latest Streptococcaceae Stories
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.
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.
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.
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.
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.
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.
ABSTRACT. Objective. A 4-year longitudinal study of school-aged children was conducted to describe the clinical characteristics and epidemiologic features of infections with group A streptococci (GAS). Methods.
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,...
