Designing vaccines against cattle brucellosis.

The article presents the results from a study of two new vaccines against cattle brucellosis from Brucella abortus cultures. One of these is a live dry vaccine prepared from a weakly agglutinogenic strain in the SR form and the second, an inactivated adjuvant vaccine from an non-agglutinogenic strain in the R form. The immunogenic properties of the vaccines were studied in three tests on heifers with infection by a virulent B.

Targeted prevention of brucellosis in cattle, sheep, and goats in the Russian Federation.

The article presents a brief history of the brucellosis prevention in animals in the world and in the Russian Federation. Data are taken from studies on the immunogenic activity and epizootic efficacy of vaccines against brucellosis in animals, which made it possible, in the final analysis, to regard these preparations as highly important for brucellosis prevention. The relationship between the epizootic brucellosis situation in Russia and the employment of specific agents in targeted prevention of brucellosis in cattle, sheep, and goats, and the sequence of their use, are presented briefly, substantiating the feasibility of their use and improvement.
