Staphylococcus saprophyticus native valve endocarditis possibly originating from the lower gastrointestinal tract
Staphylococcus saprophyticus is a common pathogen associated with uncomplicated urinary tract infection in young women and commonly colonizes in the lower gastrointestinal tract as commensal bacterium. Bacteremia or infective endocarditis caused by S. saprophyticus has rarely been reported, and in a...
