Insights

This study reports the first primary knee infection caused by Eggerthia catenaformis in a young male following anterior cruciate ligament reconstruction. Successful treatment required antibiotics, arthroscopic debridement, and lavage.

Area of Science:

  • Microbiology
  • Orthopedic Surgery
  • Infectious Diseases

Background:

  • Eggerthia catenaformis is a known human pathogen.
  • Knee infections can occur after anterior cruciate ligament reconstruction surgery.

Observation:

  • A 23-year-old male presented with a primary knee infection post-anterior cruciate ligament reconstruction.
  • Eggerthia catenaformis was identified in synovial fluid using MALDI-TOF mass spectrometry.
  • A dental source for the infection was ruled out.

Findings:

  • The isolated Eggerthia catenaformis strain was susceptible to all tested antimicrobials.
  • Effective management of the knee infection necessitated a combination of antibiotic therapy and surgical intervention.
  • Arthroscopic debridement and lavage were crucial components of the treatment protocol.

Implications:

  • This case highlights Eggerthia catenaformis as a potential cause of prosthetic joint infections.
  • It underscores the importance of prompt diagnosis and multimodal treatment strategies for managing complex orthopedic infections.
  • Further research may be needed to understand the pathogenesis and optimal treatment of Eggerthia catenaformis knee infections.

Endocarditis I: Introduction01:25

Endocarditis 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...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Acute Pyelonephritis I: Introduction

Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

Bacterial Phylum Spirochaetes01:30

Bacterial Phylum Spirochaetes

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...
