Abstract
We report on a young patient with chronic cervical lymphadenopathy and serological and histological evidence for infection with Bartonella henselae and Toxoplasma gondii. Serological follow-up studies, including testing for avidity of Toxoplasma-specific immunoglobulin G antibodies, assisted in the determination of the cause of the acute lymphadenitis. Our results suggest that the clinical symptoms were most likely due to cat scratch disease rather than to acute toxoplasmosis.
