Corynebacterium jeikeium endocarditis: A case report and comprehensive review of an underestimated infection. 

 -  2018 
<br/><br/> Diphtheroids are gram-positive pleomorphic bacilli in the family of Coryneform bacteria. These organisms are present as part of the human flora. Past practice habits had been to consider them as contaminants when isolated from clinical samples. Corynebacterium jeikeium is one of the most clinically important nondiphtherial Corynebacteria that can cause different forms of infections specifically in patients with underlying risk factors and co-morbidities including immunocompromised subjects. Through this article, we present a 67-year-old gentleman with extensive co-morbidities including heart failure with reduced ejection fraction and ESRD on hemodialysis through a femoral catheter who presented with chest pain and fatigue. Further investigation confirmed diagnosis of C. jeikeium endocarditis. We go on to review previously reported cases of C. jeikeium endocarditis and we will discuss different aspects of C. jeikeium infection with a focus on microbiology, pathophysiology, and treatment.
