Abstract

|
Infective endocarditis due to Neisseria elongata subsp. nitroreducens occurs infrequently. In this report, we describe a case of infective endocarditis caused by N. elongata subsp. nitroreducens in a patient with a prosthetic heart valve. A 55-year-old woman presented with complaints of fever and headache that she had been experiencing over the course of 4 weeks. Transesophageal echocardiography showed vegetation on the prosthetic mitral valve. A blood culture isolate was confirmed as N. elongata subsp. nitroreducens using biochemical characterization and DNA sequencing of 16S rRNA. The clinical manifestations improved with medical treatment.
