Investigation 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 کاملRole of attached lipid in immunogenicity of Borrelia burgdorferi OspA.
OspA is a protective antigen of the Lyme disease spirochete Borrelia burgdorferi. Expression of the full-length B. burgdorferi B31 OspA gene in Escherichia coli produces a protein that is processed posttranslationally by signal peptidase II and contains an attached lipid moiety. The recombinant OspA lipoprotein has been purified by detergent extraction and ion-exchange chromatography. Priming a...
متن کاملOspC is potent plasminogen receptor on surface of Borrelia burgdorferi.
Host-derived proteases are crucial for the successful infection of vertebrates by several pathogens, including the Lyme disease spirochete bacterium, Borrelia burgdorferi. B. burgdorferi must traverse tissue barriers in the tick vector during transmission to the host and during dissemination within the host, and it must disrupt immune challenges to successfully complete its infectious cycle. It...
متن کاملospC diversity in Borrelia burgdorferi: different hosts are different niches.
The outer surface protein C (ospC) locus of the Lyme disease bacterium, Borrelia burgdorferi, is at least an order of magnitude more variable than other genes in the species. This variation is classified into 22 ospC major groups, 15 of which are found in the northeastern United States. The frequency distributions of ospC within populations suggest that this locus is under balancing selection. ...
متن کاملEvolution of the Borrelia burgdorferi outer surface protein OspC.
The genes coding for outer surface protein OspC from 22 Borrelia burgdorferi strains isolated from patients with Lyme borreliosis were cloned and sequenced. For reference purposes, the 16S rRNA genes from 17 of these strains were sequenced after being cloned. The deduced OspC amino acid sequences were aligned with 12 published OspC sequences and revealed the presence of 48 conserved amino acids...
