A Second Allele of eppA in Borrelia burgdorferi Strain B31 Is Located on the Previously Undetected Circular Plasmid cp9-2

ABSTRACT Although sequence analysis of Borrelia burgdorferiisolate B31 was recently declared “complete,” we found that cultures of this strain can contain a novel 9-kb circular plasmid, cp9-2. The newly described plasmid contains both sequence similarities with and differences from the previously identified B31 plasmid cp9-1 (formerly cp9). cp9-1 and cp9-2 each encode a unique allele of EppA, a putative membrane protein synthesized by B. burgdorferiduring mammalian infection.
