Non-contiguous multifocal vertebral osteomyelitis caused by Serratia marcescens

Area of Science:

• Infectious Diseases
• Orthopedics
• Microbiology

Background:

• Serratia marcescens is a frequent cause of hospital-acquired infections.
• Vertebral osteomyelitis is typically caused by Staphylococcus aureus.
• Vertebral osteomyelitis due to Serratia marcescens is infrequently reported.

Observation:

• This case details Serratia marcescens causing vertebral discitis and osteomyelitis.
• The infection affected multiple, non-contiguous vertebrae.
• Risk factors included intravenous heroin use, post-spinal surgery, and immunosuppression.

Findings:

• Serratia marcescens can lead to severe vertebral bone infections.
• Diagnosis requires blood cultures and potentially biopsy for organism identification.
• Antibiotic susceptibility testing is essential for effective treatment.

Implications:

• Clinicians should consider Serratia marcescens in vertebral osteomyelitis cases, particularly with specific risk factors.
• Prompt and accurate diagnosis is key to successful management.
• Effective treatment relies on identifying the causative organism and its antibiotic sensitivities.
