Serratia marcescens Endocarditis

Area of Science:

• Infectious Diseases
• Cardiology
• Microbiology

Background:

• Serratia marcescens infections are increasingly reported in specific populations and hospital settings.
• Serratia marcescens endocarditis is a rare clinical manifestation.
• Opportunistic infections can arise from chronic conditions like decubitus ulcers.

Observation:

• A 50-year-old immunocompetent male with chronic paraplegia and decubitus ulcers presented with a severe infection.
• The patient likely acquired Serratia marcescens from contact with contaminated surfaces in a hotel bathroom.
• The infection was suspected to originate from a sacral wound, distinct from recent hospital admissions.

Findings:

• The case details a rare instance of Serratia marcescens endocarditis.
• The probable source of infection was identified as environmental contamination outside a healthcare facility.
• Effective management involved advanced cardiac interventions and targeted antibiotic therapy.

Implications:

• Highlights the potential for opportunistic pathogens like Serratia marcescens to cause severe infections in non-hospital settings.
• Underscores the importance of environmental hygiene, even in seemingly low-risk domestic or travel environments.
• Demonstrates the successful management of a rare Serratia marcescens endocarditis case with prompt and appropriate medical intervention.
