Bartonella henselae, formerly Rochalimæa, is a proteobacterium that is the causative agent of cat-scratch disease[1] (bartonellosis).

B. henselae is a member of the genus Bartonella, one of the most common types of bacteria in the world. It infects the host cell by sticking to it using trimeric autotransporter adhesins.

Diagnosis[edit]

B. henselae is a Gram-negative rod.[2] It can be cultured in a lysis-centrifugation blood culture.[3] The presence of bacteria can be detected by Warthin-Starry stain, or by a similar silver stain technique performed on infected tissue.

The specific name henselae honors Diane Marie Hensel (b. 1953), a clinical microbiology technologist at University of Oklahoma Health Sciences Center, who collected numerous strains and samples of the infective agent during an outbreak in Oklahoma in 1985.[4]
