Immunization against leptospirosis: vaccine trials with heat-killed whole cell and outer envelope antigens in
Bulletin of the Pan American Health Organization
|January 1, 1976
Abstract:
Heat-killed whole cell and outer envelope antigens prepared from homologous virulent and avirulent strains of Leptospira serotypes canicola and pomona were evaluated for protecting hamsters against experimental leptospirosis. The heat-killed bacterins proved at least as effective as the outer envelope antigens, or more so, in providing protection against death and infection, and they are easier and more economical to prepare.
