Thoracic empyema due to Streptococcus intermedius
Abstract:
With improved laboratory identification procedures, Streptococcus milleri (intermedius) is becoming recognized as an important human pathogen with the potential to form abscesses in a wide range of organs. The occurrence of a rapidly progressive and toxic empyema due to this organism in an otherwise healthy young adult without a predisposing lower respiratory tract infection allows us to examine the possibility that this microbe may be a significant but frequently unrecognized cause of adult empyema.
Insights
Streptococcus milleri (intermedius) can cause serious infections like empyema in healthy adults. This case highlights its potential as a significant, often overlooked, cause of lung abscesses.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Pulmonology
Background:
- Improved laboratory techniques are increasing the recognition of Streptococcus milleri (intermedius).
- This bacterium is increasingly identified as a human pathogen capable of causing abscesses in various organs.
Observation:
- A case of rapidly progressive and toxic empyema is presented in a young adult.
- The patient was otherwise healthy and lacked predisposing lower respiratory tract infections.
Findings:
- The empyema was caused by Streptococcus milleri (intermedius).
- This suggests the organism can cause severe thoracic infections without typical preceding conditions.
Implications:
- Streptococcus milleri (intermedius) may be an underdiagnosed cause of adult empyema.
- Further investigation into this pathogen's role in thoracic infections is warranted.
