Endocarditis caused by Rothia dentocariosa.

S A Broeren, M M Peel

    Journal of Clinical Pathology
    |November 1, 1984
    PubMed
    Summary
    This summary is machine-generated.

    A rare case of infective endocarditis was caused by Rothia dentocariosa, a bacterium from the mouth. A broken tooth likely allowed the oral bacteria to infect the heart in this patient with rheumatic fever history.

    Area of Science:

    • Oral microbiology
    • Infectious diseases
    • Cardiology

    Background:

    • Rothia dentocariosa is a commensal oral bacterium.
    • Recent recognition of Rothia dentocariosa as a human pathogen is emerging.
    • Infective endocarditis typically involves bacterial seeding of heart valves.

    Observation:

    • A 53-year-old male with a history of rheumatic fever presented with symptoms of infective endocarditis.
    • Rothia dentocariosa was identified as the causative agent of the endocarditis.
    • The patient had a history of poor dental hygiene, including a broken molar tooth.

    Findings:

    • The oral cavity was identified as the probable source of Rothia dentocariosa infection.
    • A fractured molar tooth served as the likely portal of entry for the bacteria into the bloodstream.

  • This case highlights Rothia dentocariosa as an etiological agent in infective endocarditis.

    • Implications:

    • This case underscores the importance of oral health in preventing systemic infections like endocarditis.
    • Rothia dentocariosa should be considered in the differential diagnosis of endocarditis, especially in patients with predisposing oral conditions.
    • Further research is warranted to understand the pathogenic mechanisms of Rothia dentocariosa and its role in infective endocarditis.
