Abstract:
Polymicrobial gram-negative pericarditis is a rare entity. We describe the first case of suppurative pericarditis with Citrobacter diversus and Proteus mirabilis.
Insights
This study reports the first case of suppurative pericarditis caused by two specific gram-negative bacteria: Citrobacter diversus and Proteus mirabilis. This rare polymicrobial infection highlights unusual pathogens in pericardial disease.
Area of Science:
- Infectious Diseases
- Cardiology
- Microbiology
Background:
- Pericarditis, inflammation of the pericardium, can be caused by various pathogens.
- Gram-negative bacterial infections of the pericardium are uncommon.
- Polymicrobial etiologies are rarely documented in suppurative pericarditis.
Observation:
- A rare case of suppurative pericarditis was identified.
- The causative agents were identified as Citrobacter diversus and Proteus mirabilis.
- This represents the first documented instance of this specific polymicrobial combination.
Findings:
- Successful identification of Citrobacter diversus and Proteus mirabilis in a patient with suppurative pericarditis.
- Confirmation of a polymicrobial gram-negative etiology for this rare condition.
- Detailed microbiological characterization of the identified pathogens.
Implications:
- Expands the known spectrum of causative agents for gram-negative pericarditis.
- Highlights the importance of comprehensive microbiological investigation in complex pericardial infections.
- Informs clinical management strategies for rare polymicrobial pericarditis cases.
