(A) The most common causes for hemorrhagic pericarditis are metastatic carcinoma and tuberculosis. Group A
Streptococcus is responsible for rheumatic fever, which acutely can lead to a fibrinous pericarditis and to serous
effusions from congestive failure in the chronic form. Coxsackieviruses are known to cause myocarditis. Candida is a
rare cardiac infection in immunocompromised persons. S. aureus is best known as a cause of infective endocarditis.
