Abstract

<abstract xml:lang="en" abstract-type="author" id="abs0010"> <title id="sectitle0010">Abstract</title> <sec> <p id="abspara0010">Culture-negative endocarditis remains a diagnostic and therapeutic challenge despite recent medical advances. <italic>Streptococcus tigurinus</italic>, a novel member of the <italic>Streptococcus mitis</italic> group, was first identified in Zurich. <italic>S. tigurinus</italic> possesses virulence determinants and causes invasive infections. We report a case of culture-negative endocarditis with serious complications due to <italic>S</italic>. <italic>tigurinus</italic>, which was identified by 16S ribosomal RNA gene sequence analysis of excised valve tissue specimens. This technique is useful for identification of the causative microorganism in patients with culture-negative endocarditis and may facilitate early diagnosis and appropriate antimicrobial treatment.</p> </sec> </abstract>
