Abstract: Infective endocarditis (IE) is a serious and life-threatening cardiac condition, most commonly caused by staphylococci, Streptococcus viridans, and enterococci. However, in special settings, IE can be caused by rare organisms. Here we present a case of IE caused by Aerococcus urinae in a 75-year-old man with a bioprosthetic aortic valve. Aerococcus urinae is a gram-positive, catalase-negative microorganism and is usually an isolate of complicated urinary tract infections in the elderly male population. . Improvements in diagnostic testing including use of matrix-assisted laser desorption ionization– a time of flight mass spectrometry (MALDI-TOF MS) have played an important role in isolating Aerococcus.

Notes :: Revised Amendments from Version 1 We added new references to the introduction about favorable outcome to IE caused by Aerococcus. We added also new references to the introduction about diagnosing IE based on the Dukes criteria or their modifications. We also discussed the rapid & sudden deterioration of the patient. The appropriate arrangements of treatment were prepared but the patient deceased prior to surgery. We also included a reference confirming that surgery isn’t indicated most of these cases. Discussion about MALDI-TOF MS remained, as we wish our readers to know that improved methods of isolation are important and could help with management Abstract and introduction re-written to reflect changes as per recommendations., , [version 2; referees: 1 approved, 1 approved with reservations]
