The outer surface proteins (Osps) of Borrelia burgdorferi, the etiologic agent of Lyme disease, are principle targets of protective immune responses against this organism. Whereas most North American strains of B. burgdorferi in culture express an abundant amount of Osp A, antibodies to this protein are either absent or only weakly detected in the sera of(More)
Transfer of immune serum from immunocompetent mice infected with B. burgdorferi protects mice against syringe challenge, and transfer of immune serum after infection is established induces arthritis resolution but does not clear infection or spirochetemia or resolve carditis. Immune serum had very-high-titer passive protective activity against syringe(More)
Listeria monocytogenes is an intracellular pathogen that secretes proteins into host cell cytosol. One such protein, the murein hydrolase p60, is processed by the host cell into the nonamer peptide p60 217-225 and presented to cytotoxic T lymphocytes by the H-2Kd MHC class I molecule. Using strains of L. monocytogenes that secrete different amounts of p60,(More)
