Safety of vaccination against brucellosis with the rough strain in pregnant cattle

Autor: João Henrique Moreira Viana, Carlos Antônio de Carvalho Fernandes, Adriana Agostini Barbosa, M. P. Palhão, A. C. S. Figueiredo

Publikováno v: Tropical Animal Health and Production. 49:1779-1781

Brucellosis is an infectious and contagious disease that profoundly impacts public health. However, in many countries, disease prevention is restricted to the vaccination of calves, and there is no prophylactic strategy for pregnant heifers and cows.
