Nosocomial acinetobacter genomic species 13 TU endocarditis following an endoscopic procedure.

We report a rare case of prosthetic valve endocarditis caused by Acinetobacter genomic species 13 TU. This patient had rheumatic heart disease and received prosthetic mitral valve replacement eleven years previously. He was admitted due to tarry stool. Endoscopic procedure showed two gastric ulcers and some mucous breaks at the distal esophagus. He had a fever on the eleventh hospital day. Persistent Acinetobacter bacteremia was noted with conjunctiva hemorrhage. The pathogen was identified as Acinetobacter genomic species 13 TU by PCR-based method. According to his whole course of disease, the most possible portal of entry was via the endoscopic procedure.
