Capnocytophaga canimorsus is a slow-growing gram-negative rod found in the normal oral flora of 20% to 25% of dogs. It is usually transmitted to humans by dog bite or exposure, causing symptoms ranging from local wound irritation to sepsis, meningitis, and death. Asplenia, alcohol abuse, and steroid use are risk factors for invasive disease, but this infection also occurs in the normal host.
