Enterococcus cecorum aortic valve endocarditis.

We report a case of human aortic valve infective endocarditis caused by Enterococcus cecorum. The organism was recovered from blood and identified by 16S ribosomal gene polymerase chain reaction (PCR). To the best of our knowledge, this is the first documented case of E. cecorum endocarditis. We wish to highlight the use of PCR for organism identification and to describe the initial misidentification of the pathogen.
