Endocarditis y artritis séptica por salmonella no typhi productora de β-lactamasas de espectro extendido

Abstract

We present the case of a patient with endocarditis and arthritis caused by extended spectrum β-lactamase producing non-Typhi Salmonella, with incomplete response (defined as persistence of Salmonella in joint fluid) to initial instituted treatment (trimethoprim-sulfamethoxazole) and posterior recovery with ertapenem. The disease was associated with implantable central venous catheter infection. Five percent of patients with non-Typhi Salmonella gastroenteritis develop bacteremia. Infective endocarditis and joint infection has been reported in 1,4% and less than 1% of cases, respectively.
