Summary
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.

01:25Pericarditis IV: Nursing Management
Pericarditis, an inflammation of the pericardium, necessitates diligent nursing management to ensure effective patient care and recovery. The initial step in managing pericarditis is a comprehensive patient medical assessment.The patient reports chest pain aggravated by breathing, coughing, and swallowing, which worsens when lying supine. The pain often improves when sitting up and leaning forward. Additional symptoms may include fever, malaise, and, in severe cases, signs of heart failure.
01:17Pericarditis III: Medical Management
The primary objectives of managing pericarditis are to determine the underlying cause, provide effective therapy for treatment and symptom relief, and promptly detect signs and symptoms of cardiac tamponade. The following outlines the essential aspects of medical management for pericarditis:ObjectivesDetermine the Cause: Identifying the underlying cause of pericarditis is crucial for targeted treatment. Causes include viral infections, autoimmune diseases, post-cardiac injury syndrome, and...
01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...

Myocarditis: Comprehensive Medical ManagementMyocarditis, the heart muscle inflammation, requires a comprehensive medical management strategy that addresses the underlying cause, provides supportive care, manages symptoms, and reduces cardiac workload.Infections and Autoimmune CausesAdminister appropriate antimicrobial therapy when an infectious agent causes myocarditis. For instance, penicillin treats infections caused by Group A Streptococcus. In cases where autoimmune processes are...
01:25Endocarditis I: Introduction
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
01:28Cardiomyopathy VII: Pre and Post Operative Nursing Management
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
