Abstract
Miller, James N. (University of California School of Medicine, Los Angeles). Immunity in experimental syphilis. III. Attenuation of virulent Treponema pallidum by gamma-irradiation. J. Bacteriol. 90:297-301. 1965.-Virulent, freshly isolated cells of Treponema pallidum strain Nichols suspended in a 50% rabbit serum-saline solution and exposed to a gamma-irradiation dosage of 652,800 r were rendered noninfectious without apparent loss of motility or change in observable morphological and staining characteristics. Although 5 x 10(7) gamma-irradiated organisms failed to elicit an immobilizing antibody response in rabbits, the same organisms retained their capacity to react with classical T. pallidum-immobilizing antibody.Entities:
