RESUMO
Cattle vaccinated with Brucella abortus rough strain RB51 (SRB51) produced small amounts of serum immunoglobulin G (IgG) but no IgM antibody to smooth strain 2308 (S2308) bacteria and produced no IgG or IgM antibody to S2308 lipopolysaccharide (LPS). Western immunoblot analysis revealed that antiserum from SRB51-vaccinated cattle contained IgG antibody that reacted with S2308 proteins of 84 to <20 kDa. However, antiserum from the vaccinated cattle did not contain agglutinating B. abortus antibody in the tube agglutination test for brucellosis. These results suggest that SRB51-vaccinated cattle produced no antibody to S2308 LPS, although they did produce nonagglutinating IgG antibody that reacted with S2308 bacteria and bacterial proteins of 84 to <20 kDa.
