First pediatric case of infective endocarditis caused by serratia liquefaciens

Abstract

Infective endocarditis (IE) caused by Serratia liquefaciens has been reported in only 2 adults. We experienced the first pediatric (neonatal) case of IE caused by S. liquefaciens, with mitral valve vegetation 4 days after a palliative heart surgery. This report underscores the importance of treating for both gram-positive and gram-negative bacteria in IE cases until the blood cultures elucidate the details.
