WORTHINGTON, R. W., MOLDERS MARIA, S. G., McFARLANE, I. S. & BECKER, DAPHNE. A serological investigation on adult cattle vaccinated with Brucella abortus strain 19. Onderstepoort ] . vet. Res. 40(1), 7-12 (1973) Serum antibody titres were followed for a period of two years in 99 beef and 29 dairy cows which had been vaccinated as adults with B. abortus strain 19. Agglutination titres remained above diagnostic levels throughout but complement fixation, mercaptoethanol agglutioation and rivanol agglutination titres generally returned to negative levels within 6 months. Coombs tests and agglutination at 56° proved to be of limited value for recognising antibody titres caused by vaccination.

Serologic responses in diagnostic tests for brucellosis in cattle vaccinated with Brucella abortus 19 or RB51.

Serologic responses in the particle concentration fluorescence immunoassay and the card, complement fixation, and tube agglutination tests were measured for 10 weeks after vaccination of cattle with either Brucella abortus 19 or the lipopolysaccharide O-antigen-deficient mutant, strain RB51. The responses of strain 19-vaccinated cattle were positive, whereas those of strain RB51-vaccinated catt...

Serological response to the outer membrane lipoprotein in animal brucellosis.

The presence of antibodies to Brucella outer membrane lipoprotein was investigated in cattle and rams. Low but significant amounts of antibody were detected in sera from B. abortus-infected cattle and from B. ovis-infected rams which had developed epididymitis. Strain-19-vaccinated cattle also showed a weak albeit transient antibody response.

Serological differentiation of Brucella-vaccinated and -infected domesticated animals by the agar gel immunodiffusion test using Brucella polysaccharide in mongolia.

To investigate Brucella infection in cattle, sheep, goat, reindeer and yak in Mongolia, serological reactions of Brucella-infected and -vaccinated domestic animals were compared by the agar gel immunodiffusion (AGID) test with a polysaccharide (poly-B) of the B. Abortus strain S-19. The sensitivity and specificity were compared with conventional serological tests that are commonly used in Mongo...

Detection of serum antibody to Brucella abortus in cattle by use of a quantitative fluorometric immunoassay.

A quantitative fluorometric immunoassay (FIAX) was adapted for the detection of serum antibodies to Brucella abortus in cattle. Results are expressed in nanograms of immunoglobulin binding the antigen carrier. The FIAX was compared with the standard tube agglutination, Rivanol precipitation, and complement fixation tests, using 285 serum samples from vaccinated, challenged, or control cattle. L...
