Isolation of Bartonella schoenbuchensis from Lipoptena cervi, a blood-sucking arthropod causing deer ked dermatitis.

Bartonella schoenbuchensis, which commonly causes bacteremia in ruminants, was isolated from the deer ked Lipoptena cervi and was shown to localize to the midgut of this blood-sucking arthropod, causing deer ked dermatitis in humans. The role of B. schoenbuchensis in the etiology of deer ked dermatitis should be further investigated.
