Infective endocarditis due to Escherichia Coli on native valve in sepsis of urinary origin.

Abstract

Escherichia coli is a common cause of urinary tract infection and bacteremia, especially in older adults, but it is only attributed to 0.51% of cases as the etiological agent of infective endocarditis.

Here we review a case of a 68 years old woman with a history of poorly controlled type II diabetes mellitus and stage V chronic kidney disease, who presented with a urinary tract infection complicated by septic shock, with positive blood cultures for non extended-spectrum betalactamases (non-ESBL) E.coli and vegetations on the mitral valve compatible acute endocarditis. She was medically treated with Ampicillin/Sulbactam for six weeks with a satisfactory clinical response and resolution of vegetations. What we found on this patient, puts into consideration this microorganism from non-HACEK group, as a part of the etiological agents of infectious endocarditis.
