Cerebral abscess caused by Capnocytophaga spp in an immunocompetent subject: case report.
Capnocytophaga spp are Gram-negative bacteria commonly identified as oral saprophytes of humans, dogs and cats; they rarely cause invasive infections in immunocompetent subjects. This case report is about a rare case of cerebral abscess caused by Capnocytophaga spp in an immunocompetent subject who had no risk factors for Capnocytophaga invasive infections (oral alterations, traumatic or iatrogenic lesions of pharynx and/or oesophagus, recent dog bite). We also report Capnocytophaga spp naturally resistant to metronidazole, this being the cause of inefficacy of this drug usually included in empiric chemotherapy of cerebral abscess.
