Bartonella henselae Associated with Parinaud's Oculoglandular Syndrome

Abstract

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