Gram-negative bacteria causing infective endocarditis: Rare cardiac complication after liver transplantation

Bacterial endocarditis is a rare complication amongst solid organ transplant recipients and is often linked to bacteremia. Majority of these recipients do not have underlying valvular heart disease or congenital valvular abnormalities. Staphylococoocusaureus and Enterococcus species are the most commonly isolated organisms. There are very few reports of gram-negative bacteria causing endocarditis in liver transplant recipients. We report a 51-year-old male, a liver transplant recipient, who developed bacterial endocarditis of the mitral valve due to extended spectrum of betalactamase producing strain of Escherichia coli and was managed successfully with antibiotics.
