Designing vaccines against cattle brucellosis. | LitMetric

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. abortus culture. The vaccines passed the farm-scale testing and were accepted in veterinary practice.
