F R Sattler, J Ruskin

    Chest
    |February 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Streptococcus mutans, a dental pathogen, caused empyema in two patients after dental work. Penicillin treatment was effective, highlighting the oropharynx as the infection source.

    Area of Science:

    • Medical microbiology
    • Pulmonary medicine
    • Infectious diseases

    Background:

    • Periodontal disease can predispose individuals to systemic infections.
    • Dental manipulation is a known risk factor for certain infections.
    • Empyema is a serious infection of the pleural space.

    Observation:

    • Two cases of empyema were identified.
    • The causative agent was isolated as Streptococcus mutans.
    • Patients had a history of periodontal disease and recent dental manipulation.

    Findings:

    • Isolation of Streptococcus mutans from pleural fluid localized the infection origin to the oropharynx.
    • This finding eliminated the need to investigate for remote intra-abdominal sources.
    • The Streptococcus mutans isolates were highly sensitive to penicillin.

    Related Experiment Videos

  • Both patients achieved successful outcomes with penicillin therapy and surgical drainage.

    • Implications:

    • Streptococcus mutans should be considered in the differential diagnosis of empyema, especially in patients with dental issues.
    • Early identification of the pathogen can guide targeted antibiotic therapy.
    • This study supports the use of penicillin for susceptible Streptococcus mutans infections.
    • Understanding the oropharyngeal origin of these empyemas aids in infection control and prevention strategies.
