She noticed bleeding spots on her feet this morning. The past medical history is significant for a recent dental appointment. She is a non-smoker and does not drink alcohol. She does not currently take any medications. On examination, the vital signs include temperature 37.8C 100.0F, blood pressure 13890 mm Hg, respirations 21min, and pulse 87min. Cardiac auscultation reveals a pansystolic murmur in the mitral area with radiation to the right axilla. Laboratory studies show hemoglobin levels of 17.2 gdL, erythrocyte sedimentation rate ESR of 25 mmh, and a white blood cell WBC count of 12,000 cellsmm3. An echocardiogram ECG reveals valvular vegetations on the mitral valve with mild regurgitation. Blood samples are sent for bacterial culture. Empiric antibiotic therapy is initiated with ceftriaxone and vancomycin. The blood cultures most likely will yield the growth of which of the following organisms?? A: Staphylococcus aureus, B: Actinomyces israelii, C: Streptococcus viridans, D: Group B Streptococcus, E: Coxiella burnetii,  <response>: This is a patient with signs and symptoms of infective endocarditis, including fever, heart murmur, and valvular vegetations seen on echocardiogram. The history of a recent dental procedure suggests the infection was introduced through a bacteremia from that procedure. The organism choices include Staphylococcus aureus, Actinomyces israelii, Streptococcus viridans, Group B Streptococcus, and Coxiella burnetii. Streptococcus viridans is the most likely organism to cause subacute bacterial endocarditis following a dental procedure. Staph aureus more often causes acute endocarditis. Actinomyces and Group B Strep are less common causes. Coxiella burnetii causes Q fever endocarditis which is also less likely here.C: Streptococcus viridans
