Question 2
A 64-year-old female was admitted for removal of a ruptured appendix. Her medical history was unremarkable except for a case of rheumatic fever as a child that left her with an audible heart murmur.
Three months after the surgery, she saw her physician complaining of fever, chills, fatigue, and dizziness for several weeks. The physician noted that her heart murmur was much more pronounced. He ordered two sets of blood cultures to be drawn. Both sets of blood cultures grow gram-positive cocci in pairs and chains. The gray, gamma-hemolytic colony is catalase negative. It hydrolyzes esculin in the presence of bile and grows in 6.5 salt broth. Given this patient history and organism isolated, the infectious disease present is
A) Acute bacterial endocarditis B) Subacute bacterial endocarditis
C) Transient bacteremia D) Septic shock
