Abstract
We detected infection with aBartonellaspecies (B. henselaeorB. vinsoniisubsp.berkhoffii) in blood samples from six immunocompetent patients who presented with a chronic neurological or neurocognitive syndrome including seizures, ataxia, memory loss, and/or tremors. Each of these patients had substantial animal contact or recent arthropod exposure as a potential risk factor forBartonellainfection. Additional studies should be performed to clarify the potential role ofBartonellaspp. as a cause of chronic neurological and neurocognitive dysfunction.
