Endocarditis Caused by Abiotrophia Defectiva in Children

Abstract

Abiotrophia defectiva, formerly designated as the member of nutritionally variant streptococci, is a part of normal oral flora and may be a cause of culture-negative endocarditis. We report a case of infective endocarditis caused by A defectiva involving the mitral valve in a 12-year -old girl. She received antibiotic treatment for 8 weeks and was symptom- free 6 months after discharge. We also reviewed the pediatric cases of nutritionally variant streptococcal endocarditis published in the English literature since 1971.
