The goal of the experiment was to evaluate the Boviseptivac vaccine against cattle pasteurellosis manufactured from local isolates of P. multocida serotype B:2 with the addition of an oil adjuvant (Emulsigen). Field examinations were performed on 645 cows in the Ostroleka province. The vaccine effectively protected against the disease; however, 6 (93%) of examined cows revealed shock signs which were lessened with anti-shock preparations. The immunogenicity of the vaccine was determined by the agar gel diffusion precipitin test and ELISA. Examined blood was sampled from 10 cows before vaccination and 2, 4 and 8 months thereafter. The vaccine stimulated the production of specific precipitins to serotype 2 and increased levels of the IgG anti-P. multocida.
