The cryptic ospC gene of Borrelia burgdorferi B31 is located on a circular plasmid.

چکیده
Borrelia burgdorferi B31 cells lacking all linear plasmids or all but the 49-kb linear plasmid expressed the otherwise silent gene for the outer membrane protein OspC. In the first demonstration of a function for a circular plasmid of Borrelia spp., ospC was located on a 27-kb circular plasmid of B31.

A second allele of eppA in Borrelia burgdorferi strain B31 is located on the previously undetected circular plasmid cp9-2.
Although sequence analysis of Borrelia burgdorferi isolate 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 putativ...
متن کاملInvestigation of ospC Expression Variation among Borrelia burgdorferi Strains
Outer surface protein C (OspC) is the most studied major virulence factor of Borrelia burgdorferi, the causative agent of Lyme disease. The level of OspC varies dramatically among B. burgdorferi strains when cultured in vitro, but little is known about what causes such variation. It has been proposed that the difference in endogenous plasmid contents among strains contribute to variation in Osp...
متن کاملIdentification of a protein in several Borrelia species which is related to OspC of the Lyme disease spirochetes.
Using oligonucleotide probes which have previously been shown to be specific for the ospC gene found in the Lyme disease spirochete species Borrelia burgdorferi, B. garinii, and group VS461, we detected an ospC homolog in other Borrelia species including B. coriaceae, B. hermsii, B. anserina, B. turicatae, and B. parkeri. In contrast to the Lyme disease spirochetes, which carry the ospC gene on...
متن کاملTranscriptional analyses and mapping of the ospC gene in Lyme disease spirochetes.
In Lyme disease spirochetes, the ospC gene encodes a 22.7-kDa protein referred to as either the pC or the OspC protein. Using a variety of electrophoretic approaches followed by Southern blotting and probing with oligonucleotide probes, we mapped the ospC gene to a circular 26-kb plasmid. The ospC gene represents the first gene to be mapped to a circular plasmid in Lyme disease spirochetes. The...
متن کاملDecreased infectivity in Borrelia burgdorferi strain B31 is associated with loss of linear plasmid 25 or 28-1.
Previous reports indicated a correlation between loss of plasmids and decreased infectivity of Borrelia burgdorferi strain B31, suggesting that plasmids may encode proteins that are required for pathogenesis. In this study, we expand on this correlation. Using the B. burgdorferi genomic sequence, we designed primers specific for each plasmid, and by using PCR we catalogued 11 linear and 2 circu...
