The flagellin gene from the P/Gau strain of Borrelia burgdorferi was cloned and sequenced. The translated P/Gau flagellin protein differed from the flagellin of the B31 strain at 13 of 336 amino acids. This includes seven differences between amino acids 190-234, an immunodominant and specific region for B. burgdorferi. The entire flagellin molecule, as well as peptides of the internal portion of the protein which is more specific for B. burgdorferi, has been expressed in Escherichia coli using a pET7HIs.2 expression system. These peptides may be of great value for the development of sensitive and specific recombinant-based serological assays. © 1992.
