Cat-scratch disease results from infection with Bartonella henselae. The organism is transmitted to humans typically from a scratch or bite from an infected cat in the 2 weeks preceding symptom onset. Most infections are characterized by localized lymphadenopathy and low-grade systemic features that clear spontaneously. On rare occasion, encephalopathy, seizures, and other neurologic manifestations may accompany cat-scratch disease.
