Bartonella henselae associated with Parinaud's oculoglandular syndrome

Bartonella henselae was recovered from the conjunctival scraping of a 38-ye ar-old woman who presented with a 2-week history of tender preauricular lym phadenopathy and a 1-day history of a red left eye. Dry adherent colonies w ere observed on agar plates at 21 days of incubation, and the isolate was i dentified through conventional and molecular tests. Polymerase chain reacti on (PCR) amplification of a specific region of the 16S rRNA gene and confir mation by a separate PCR reaction with hybridization of the product with a B. henselae-specific probe confirmed the isolate as B. henselae. This is th e first reported isolation of the causative agent of cat scratch disease fr om ocular tissue in a patient with Parinaud's oculoglandular syndrome.
