Immunization against Erysipelothrix rhusiopathiæ with Killed Vaccine

Oral immunization of mice with killed Salmonella typhimurium vaccine.

A study was undertaken to assess the efficacy of oral, parenteral, and intraperitoneal immunization methods of administering killed Salmonella typhimurium vaccine to mice and to evaluate the effectiveness of single and multiple doses of the vaccine containing varied numbers of the killed bacteria. A further objective of this study was to evaluate the effect of adding substances to the vaccine t...

Immunization against leptospirosis: vaccine trials with heat-killed whole cell and outer envelope antigens in hamsters.

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...

Use of Sodium Alginate Adjuvant in Preparation of a Formalin Killed Vaccine Against Infectious Bovine Rhinotracheitis

Subcutaneous immunization against Leishmania major - infection in mice: efficacy of formalin-killed promastigotes combined with adjuvants.

Formalin-killed promastigotes (FKP) of Leishmania major, in combination with Montanide ISA 720 (MISA), BCG or alum were used in vaccination of an inbred murine model against cutaneous leishmaniasis (CL). Significant and specific increases in anti-FKP IgG responses were detected for both alum-FKP and BCG-FKP compared to MISA-FKP (p < 0.001). Significant increases in splenic lymphocyte recall pro...

Immunization against Egyptian Schistosoma mansoni infection by multivalent DNA vaccine.

The development of multivalent vaccines consisting of several antigens is a novel approach to creating broad-range protection against different parasite strains and parasite life cycle stages. We have previously confirmed that the schistosome Sm21.7 and SmFimbrin (SmFim) proteins could induce protection in mice. Therefore, this study aimed to construct the multivalent DNA vaccine Sm21.7-SmFim/p...
