Outer Surface Protein B Is Critical for Borrelia burgdorferi Adherence and Survival within Ixodes Ticks
Survival of Borrelia burgdorferi in ticks and mammals is facilitated, at least in part, by the selective expression of lipoproteins. Outer surface protein (Osp) A participates in spirochete adherence to the tick gut. As ospB is expressed on a bicistronic operon with ospA, we have now investigated the role of OspB by generating an OspB-deficient B. burgdorferi and examining its phenotype through...
متن کاملExpression and Purification of Recombinant Outer Surface Protein D of Borrelia burgdorferi
To carry out the immunological experiments on the serum of Multiple Sclerosis (MS) patients, based on a correlation between Borrelia burgdorferi infection and contracting MS autoimmune disease the outer surface protein D (OspD) of the bacterium was expressed and purified. A clone containing the OspD gene in pET11a expression vector under the control of T7 promoter was transformed to the bacteri...
متن کاملIdentification of Two Epitopes on the Outer Surface Protein A of the Lyme Disease Spirochete Borrelia burgdorferi
A murine IgM monoclonal antibody (MA-2C6) with κ-light chains directed against an antigenic determinant of outer surface protein A (OspA) of the Lyme disease spirochete, Borreliaburgdorferi, is produced. This antibody could bind specifically to OspA antigen of several isolates of B. burgdorferi, but not to the non-Lyme disease bacteria such as T. pallidum and B. hermsii. Antibody MA-2C6 was pur...
متن کاملNatural antibody affects survival of the spirochete Borrelia burgdorferi within feeding ticks.
Natural antibodies are those immunoglobulin molecules found in mammalian serum that arise in the absence of exposure to environmental pathogens and may comprise an early host defense against invading pathogens. The spirochete Borrelia burgdorferi first encounters natural antibodies when its arthropod vector, Ixodes scapularis, begins feeding on a mammalian host. Natural antibodies may therefore...
متن کاملInhibition of Borrelia burgdorferi-tick interactions in vivo by outer surface protein A antibody.
Borrelia burgdorferi outer surface protein (Osp) A is preferentially expressed by spirochetes in the Ixodes scapularis gut and facilitates pathogen-vector adherence in vitro. Here we examined B. burgdorferi-tick interactions in vivo by using Abs directed against OspA from each of the three major B. burgdorferi sensu lato genospecies: B. burgdorferi sensu stricto, Borrelia afzelii, and Borrelia ...
