Endocarditis due to Chryseobacterium meningosepticum

Area of Science:

• Microbiology
• Infectious Diseases
• Cardiology

Background:

• Chryseobacterium meningosepticum is a gram-negative bacterium found in the environment.
• It is a known cause of meningitis in neonates and premature infants.
• Adult infections are infrequent and typically hospital-acquired.

Observation:

• A 58-year-old male patient presented with an unusual infection.
• The patient was diagnosed with native valve endocarditis.
• The causative agent identified was Chryseobacterium meningosepticum.

Findings:

• This case represents a rare occurrence of Chryseobacterium meningosepticum causing endocarditis in an adult.
• The infection involved the patient's native heart valve.
• Accurate identification and antimicrobial susceptibility testing are crucial for managing such rare infections.

Implications:

• Clinicians should maintain a high index of suspicion for Chryseobacterium meningosepticum in unusual adult infections.
• Prompt and accurate laboratory identification is essential for effective treatment.
• This case expands the spectrum of known clinical manifestations of Chryseobacterium meningosepticum infections.
