ospa sequence comparison and protection against borrelia burgdorferi infection in gerbils by recombinant ospa protein
lyme borreliosis is a tick-born disease caused by the spirochete borrelia burgdorferi. the aim of this research was molecular typing of different strains of b. burgdorferi and protective efficacy of outer surface protein in animal model. seven strains of b. burgdorferi isolated from skin and csf of lyme disease patients were compared using pcr- rflp as well as dna and amino acid sequences. the ...
متن کاملHost-adapted Borrelia burgdorferi in mice expresses OspA during inflammation.
Antibody responses to outer surface protein A (OspA) of Borrelia burgdorferi may occur during periods of arthritis late in the clinical course of untreated Lyme disease. These antibody responses are paradoxical, given the conclusive evidence demonstrating that B. burgdorferi transmitted to the mammalian host expresses little or no OspA. The parallel occurrence of OspA antibodies and arthritic e...
متن کاملBorrelia burgdorferi OspA is an arthropod-specific transmission- blocking Lyme disease vaccine
Borrelia burgdorferi, the spirochetal agent of Lyme disease, is transmitted by Ixodes ticks. A vaccine based on B. burgdorferi outer surface protein (Osp) A protects mice from spirochete infection. Here we report on the expression of OspA on spirochetes inside engorging ticks and relate OspA expression to antispirochetal immunity. Spirochetes in the gut of unfed nymphal ticks were stained by an...
متن کاملBlocking pathogen transmission at the source: reservoir targeted OspA-based vaccines against Borrelia burgdorferi
Control strategies are especially challenging for microbial diseases caused by pathogens that persist in wildlife reservoirs and use arthropod vectors to cycle amongst those species. One of the most relevant illnesses that pose a direct human health risk is Lyme disease; in the US, the Centers for Disease Control and Prevention recently revised the probable number of cases by 10-fold, to 300,00...
متن کاملExperimental Borrelia burgdorferi infection of outbred mice.
Infectivity of Borrelia burgdorferi strain 297 in normal outbred ddY mice was examined. Strain 297 was inoculated intraperitoneally in 3-week-old outbred ddY mice. B. burgdorferi was routinely cultured from the heart and urinary bladder 5 to 84 days postinoculation. The combined isolation rate from both heart and urinary bladder was significantly higher than the rate from spleen, kidney, liver,...
