Introduction:
Infective endocarditis (IE) caused by Klebsiella species is an infrequent occurrence, comprising less than 1.2% of native valve endocarditis cases and up to 4.1% of prosthetic valve endocarditis cases. 1,2 The majority of such cases are caused byK. pneumoniae. 3,4 K. oxytoca is an extremely rare species that can rarely cause endocarditis. Here, we present a case of K. oxytoca endocarditis to highlight the need for careful evaluation during the entire course of therapy and the role of advanced imaging and molecular techniques.
