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.

N. elongata subsp. nitroreducens는 비인두강의 상재균이지만 기저 심장 질환이 있거나 치과 시술을 받은 환자에서 드물게 심내막염을 일으킬 수 있다. 저자들은 인공판막을 가진 환자에서 발생한 N. elongata subsp. nitroreducens에 의한 감염성 심내막염을 진단하고 수술적 치료 없이 항생제 치료만으로 호전된 1예를 경험하였기에 보고하는 바이다.
