(strep) A genus of the family Micrococcaceae, as is the Staphylococcus bacteria, and are most often found as the normal flora of healthy people. According to the Lancefield system, they are divided into eighteen major groups designated A through R. Group A is responsible for most of the fatal illnesses, including the "flesh eating" infections, as well as strep throat, scarlet fever, and rheumatic fever. Group B generally cause such diseases as neonatal meningitis and sepsis. Groups C and G are responsible for the occasional wound infection and pharyngitis. Group D (enterococci) are mainly responsible for urinary tract infections, bacteremia, and endocarditis. Viridans streptococci contains about ten species responsible for about 70% of all cases of bacterial endocarditis. Streptococcus mutans plays a central role in the initiation of cavities.
spherical gram-positive bacteria occurring in pairs or chains; cause e.g. scarlet fever and tonsillitis
a bacteria that may be found commonly in the skin, nose, and throat of many individuals
a bacterium commonly found in the throat and on the skin that can cause a range of infections, from relatively mild sore throats and skin infections to life-threatening disease
a bacterium often found in the and on the skin
a biological transformation of the skin or tissue cells
a focus of diagnosis due to its potential for preventable rheumatic sequelae
a gram-positive coccus that frequently colonizes the skin and oropharynx
a pathogenic bacterium that causes many types of human infections, including sore throats, rheumatic heart disease, and necrotizing fasciitis (the "flesh-eating" syndrome)
a group of bacteria which cause a wide variety of infections including those of skin and wounds. More serious infections include scarlet fever and pneumonia.
A bacterium that causes infections such as strep throat. Doctors think that it also may trigger Behçet's disease in some people.
spherical bacteria, occurring in chains; some species cause serious diseases
A group of bacteria, familiarly known as strep, that cause a multitude of diseases. The name comes from the Greek strepto- meaning twisted + kokkos meaning berry, and that is exactly what strep look like under the microscope, like a twisted bunch of little round berries. Illness caused by strep includes strep throat, strep pneumonia, scarlet fever, rheumatic fever (and rheumatic heart valve damage), glomerulonephritis, the skin disorder erysipelas, and PANDAS.
A category (genus) of sphere-shaped bacteria that occur in pairs or chains.
Bacteria responsible for diseases such as bacterial pneumonia, scarlet fever, and rheumatic fever. They also cause "strept" throat, a severe sore throat that is common in children and is sometimes found in adults.
A genus of gram-posativespherically shaped bacteria in microscopic chains.
Streptococcus is a genus of spherical, Gram-positive bacteria, and a member of the phylum Firmicutes. Streptococci are lactic acid bacteria.
