An immunocompetent patient developed severe septic shock and meningitis following a dog bite, presenting with rapid deterioration. The causative agent was identified as Capnocytophaga canimorsus (serovar B), a Gram-negative rod typically found in canine oral microflora. Diagnosis was confirmed through microbiological methods. This case highlights that while severe C. canimorsus infections are rare in immunocompetent individuals, they can still lead to life-threatening conditions like septic shock and meningitis, emphasizing the importance of considering this pathogen even in patients without typical risk factors. Prompt diagnosis and aggressive treatment are crucial for favorable outcomes.
Key note: Capnocytophaga canimorsus can cause severe, life-threatening infections in immunocompetent individuals following dog bites, necessitating vigilance.
