How does Streptococcus pyogenes cause rheumatic fever?
pyogenes isolates to bind collagen, and the presence of collagen-reactive autoantibodies in the serum of rheumatic fever patients, which may form a basis for post-streptococcal rheumatic disease. These anti-collagen antibodies may form a basis for poststreptococcal rheumatic disease.
What is the cause of rheumatic heart disease?
What causes rheumatic heart disease? Rheumatic heart disease is caused by rheumatic fever, an inflammatory disease that can affect many connective tissues, especially in the heart, joints, skin, or brain. The heart valves can be inflamed and become scarred over time.

What organisms are commonly implicated in bacterial endocarditis?
Two kinds of bacteria cause most cases of bacterial endocarditis. These are staphylococci (staph) and streptococci (strep). You may be at increased risk for bacterial endocarditis if you have certain heart valve defects. This gives the bacteria an easier place to take hold and grow.
Can Group C strep cause rheumatic fever?
Group C Streptococcus is rarely associated with rheumatic heart disease and most children exhibiting acute onset of common symptoms, such as chorea, fever, carditis, and rash (erythema marginatum) will present to the emergency department first.

Group A strep bacteria spread through contact with droplets from an infected person when they talk, cough, or sneeze.
What causes Streptococcus?
Strep infection may lead to inflammatory illnesses, including: Scarlet fever, a streptococcal infection characterized by a prominent rash. Inflammation of the kidney (poststreptococcal glomerulonephritis) Rheumatic fever, a serious inflammatory condition that can affect the heart, joints, nervous system and skin.
What bacteria causes strep throat?
Bacteria cause strep throat Viruses are the most common cause of a sore throat. However, strep throat is an infection in the throat and tonsils caused by bacteria called group A Streptococcus (group A strep).
How do you get Streptococcus bacteria?
These bacteria are spread by direct contact with discharges from the nose and throat of infected people or by contact with infected wounds or sores on the skin. The risk of spreading the infection is highest when a person is ill, such as when people have “strep throat” or an infected wound.
What bacteria causes acute bacterial endocarditis?
Two kinds of bacteria cause most cases of bacterial endocarditis. These are staphylococci (staph) and streptococci (strep). You may be at increased risk for bacterial endocarditis if you have certain heart valve defects.
