Decorin binding protein essential peptides and methods of use

Abstract

Borrelia burgdorferi, the causative agent of Lyme disease, expresses on its surface a decorin binding protein, DbpA and DbpB. Lysine residues necessary for DbpA binding to decorin and DbpA peptides containing these critical residues essential for decorin binding are disclosed. It is further disclosed that vaccination using peptides incorporating these critical binding domains of DbpA can confer a delayed-type hypersensitivity response to DbpA and reduce the number of B. burgdorferi organisms present in infected animals.
