Escherichia coli urosepsis leading to native valve endocarditis

Abstract

Escherichia coli, a Gram-negative facultative anaerobe, is the common causative organism leading to urinary tract infection. However, the involvement of endocardium by E. coli has been reported to be very rare in spite of the septicemia caused by this organism. However, the mortality rate due to infective endocarditis caused by E. coli was reported to be higher than due to other organisms like HACEK group of organisms. Conventional risk factors leading to infective endocarditis include cirrhosis of the liver, prosthetic heart valves, and other sources of infection like urosepsis. Here, we report the case of a 60-year-old diabetic male who presented with obstructive uropathy-induced urinary tract infection leading to infective endocarditis.
