Q: 57 year old male is admitted via ED to ICU with sepsis. Blood cultures drawn in ED grew 2 of 2 bottles positive culture for Abiotrophia. Next day patient developed right sided hemiplegia. What would be your concern?

Answer: Possible Endocarditis

Abiotrophia in humans is a resident of oral, urogenital and intestinal tracts,  and can be a cause of infective endocarditis. Also it may raise suspicion of underlying intestinal malignancy if there is no previous history of valve or prosthetic surgeries or of dental work.
