Brucellosis in cattle, sheep and goats: diagnosis, control and vaccination*

Reports received from forty-eight countries constitute a representative sample which demonstrates the universality of the problems created by brucellosis, and the wide range of control measures which have been adopted. Among the forty-eight countries, thirteen have obtained complete eradication of the disease, seventeen are in the process of more or less advanced clearance, eight have a vaccination programme primarily designed to decrease prevalence of the disease and ten do not yet have well-defined applicable measures.
