The administration of foot and mouth disease vaccine with oil adjuvant and its influence on the diagnosis of bovine tuberculosis.

The possible influence of vaccination with oil adjuvanted foot and mouth disease vaccines on the tuberculin response was investigated in 32 normal guinea pigs and 190 non-tuberculous bovines. Circulating anti-Mycobacterium bovis IgG antibodies were analysed by an enzyme-linked immunosorbent assay (ELISA), in order to determine the effect of the vaccination on the humoral response against mycobacteria in cattle. Control animals were either nonvaccinated or injected with aluminium hydroxide adjuvanted vaccine. Administration of foot and mouth disease vaccine had no apparent influence on the tuberculin responses of either guinea pigs or cattle, nor did it influence the level of anti-M. bovis antibodies in cattle.
