Preferential Presence of Decorin-Binding Protein B (BBA25) and BBA50 Antibodies in Cerebrospinal Fluid of Patients with Neurologic Lyme Disease

摘要

Borrelia burgdorferi antibodies preferentially present in cerebrospinal fluid (CSF) were examined by differentially probing a B. burgdorferi expression library with CSF and sera from patients with neurologic Lyme disease. Several phage clones selectively reacted with CSF, and these genes were then expressed in recombinant form and used to detect specific antibody in an enzyme-linked immunosorbent assay. Decorin-binding protein B (BBA25) and BBA50 (hypothetical protein) elicited immunoglobulin G (IgG) or IgM detectable in CSF—but not sera—of patients, demonstrating preferential antibody production during neuroborreliosis.
