Streptococcus constellatus, a common oropharyngeal bacterium, can cause severe empyema, particularly in patients with liver conditions. This case highlights the need to recognize its potential for serious infections despite its commensal nature.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Pulmonology
Background:
- Streptococcus constellatus is an oropharyngeal commensal Gram-positive coccus.
- It belongs to the Streptococcus anginosus group, known for causing purulent infections like empyema and abscesses.
- The severity of S. constellatus infections can vary and is sometimes underestimated.
