Insights

Infective endocarditis (IE) is serious. This case report details the first instance of IE caused by Salmonella enterica phagetype 35 (PT35) in a patient who consumed contaminated food.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Microbiology

Background:

  • Infective endocarditis (IE) presents significant morbidity and mortality.
  • While Gram-positive bacteria are common causes, emerging Gram-negative pathogens like *Acinetobacter*, *Bartonella*, *Chlamydia*, and *Legionella* are increasingly implicated.
  • Cardiovascular infections from *Salmonella enterica* are rare, with limited understanding of their clinical course and management.

Observation:

  • A case of infective endocarditis is presented in a 74-year-old woman.
  • The causative agent identified was *Salmonella enterica* phagetype 35 (PT35).
  • The patient reported consuming baked pasta from a rotisserie prior to symptom onset.

Findings:

  • This study reports the first known case of infective endocarditis caused by *Salmonella enterica* PT35.
  • The isolation of *S. enterica* PT35 from blood and heart cavity samples confirmed the diagnosis.
  • The patient's consumption of contaminated food was identified as a potential source of infection.

Implications:

  • This case expands the spectrum of pathogens causing infective endocarditis.
  • Highlights the need for considering *Salmonella enterica* in the differential diagnosis of IE, especially with a history of foodborne exposure.
  • Further research is needed to elucidate the specific clinical features, prognosis, and optimal treatment strategies for *Salmonella enterica*-associated endocarditis.

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...

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...

Endocarditis III: Medical Management

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...
