Antibody responses to p66, a candidate integrin ligand of
Borrelia burgdorferi, were studied in 79 patients with
early or late manifestations of Lyme disease. The central portion of
p66 was previously shown to contain all of the information required for
specific recognition of

Recognition of Multiple Antibody Epitopes
throughout Borrelia burgdorferi p66, a Candidate Adhesin, in
Patients with Early or Late Manifestations of Lyme Disease
3-chain integrins, but work by
others had suggested that the C-terminal portion of the protein
contains a single surface-exposed, immunodominant loop. In examining
antibody responses to full-length p66 and to three overlapping
fragments of the protein, we found that the majority of Lyme disease
patients had immunoglobulin M (IgM) and/or IgG responses to p66 and
that, particularly early in the disease, epitopes throughout p66 were recognized. Among patients with later manifestations of the illness, antibody responses to the C-terminal portion of the protein were more
prominent. These results demonstrate that Lyme disease patient sera
recognize epitopes throughout p66.
