Protection of C3H/HeN mice from challenge with Borrelia burgdorferi through active immunization with OspA, OspB, or OspC, but not with OspD or the 83-kilodalton antigen.
Recent advances in the development of animal models for Lyme borreliosis have provided means of identifying potential targets for the design of a subunit vaccine to prevent this disease. The C3H/HeN mouse model was used to study several Borrelia burgdorferi antigens from a single isolate for their ability to elicit borreliacidal and protective antibodies. The ospA, ospB, ospC, ospD, and 83-kDa ...
متن کاملResolution of experimental and tick-borne Borrelia burgdorferi infection in mice by passive, but not active immunization using recombinant OspC.
Vaccination with outer surface protein A (OspA) of Borrelia burgdorferi prevents subsequent infection and disease in both laboratory animals and humans with high efficacy. OspA-based immunity, however, does not affect established infection due to the loss of OspA expression in the vertebrate host. We show here that repeated passive transfer of mouse and/or rabbit immune sera to recombinant GST-...
متن کاملBorrelia burgdorferi sigma54 is required for mammalian infection and vector transmission but not for tick colonization.
Previous studies have shown that a sigma54-sigma(S) cascade regulates the expression of a few key lipoproteins in Borrelia burgdorferi, the agent of Lyme disease. Here, we demonstrate that these sigma factors, both together and independently, regulate a much more extensive number of genes and cellular processes. Microarray analyses of sigma54 and sigma(S) mutant strains identified 305 genes reg...
متن کاملEnhancement of OspC expression by Borrelia burgdorferi in the presence of tick hemolymph.
Borrelia burgdorferi B31 cultured at 28 degrees C was used to assay the effects of tick hemolymph on outer surface protein C (OspC) surface expression. Using immunofluorescence, OspC surface expression was shown to increase in cultures treated with hemolymph from both Ixodes scapularis and Dermacentor variabilis, while control samples (non-hemolymph treated) showed no increase in the levels of ...
متن کاملOral Immunization with OspC Does Not Prevent Tick-Borne Borrelia burgdorferi Infection
Oral vaccination strategies are of interest to prevent transmission of Lyme disease as they can be used to deliver vaccines to humans, pets, and to natural wildlife reservoir hosts of Borrelia burgdorferi. We developed a number of oral vaccines based in E. coli expressing recombinant OspC type K, OspB, BBK32 from B. burgdorferi, and Salp25, Salp15 from Ixodes scapularis. Of the five immunogenic...
