Abstract:
We discuss a case of meningitis caused by Capnocytophaga canimorsus (C. canimorsus) infection in a previously healthy elderly male who presented with altered mental status and new-onset seizures requiring intensive care. An open wound had served as an entry point for the infectious organism. After 25 days of treatment with meropenem, he recovered with persistent functional limitations and was discharged. We also engage in a review of the relevant literature and highlight the importance of identifying animal exposure in patients with meningitis.
Insights
Capnocytophaga canimorsus meningitis is a rare but serious infection. Prompt identification of animal exposure is crucial for diagnosing and treating this potentially fatal condition.
Area of Science:
- Neurology
- Infectious Diseases
- Microbiology
Background:
- Capnocytophaga canimorsus is a bacterium commonly found in the mouths of dogs and cats.
- Infection can occur through bites, scratches, or even casual contact with infected animals.
- Meningitis is a severe inflammation of the membranes surrounding the brain and spinal cord.
Observation:
- A previously healthy elderly male presented with altered mental status and new-onset seizures.
- The patient had an open wound, serving as the entry point for Capnocytophaga canimorsus.
- The patient required intensive care for the C. canimorsus meningitis.
Findings:
- The patient was treated with meropenem for 25 days.
- Recovery was achieved, but with persistent functional limitations.
- This case highlights the potential severity of C. canimorsus infections.
Implications:
- Clinicians should inquire about animal exposure in patients presenting with meningitis symptoms.
- Early diagnosis and appropriate antibiotic treatment are critical for favorable outcomes.
- Raising awareness about zoonotic diseases like C. canimorsus meningitis is important for public health.
