Abstract

The detection limits for purified bovine IgM, IgG1 and IgG2 antibody to Brucella abortus in the haemolysis in gel test and in an enzyme-linked immunosorbent assay (ELISA) were established. The limits for IgM, IgG1 and IgG2, respectively, were: 5500, 60 and 4850 ng of antibody in the lytic test and 2750, 3.5 and 16 ng in the ELISA test. Bovine IgG2 produced lysis only in the presence of fresh, whole bovine serum.

Brucellosis

Brucellosis is a bacterial infection caused by members of the genus brucella and remains one of the world's major zoonotic diseases. Discover the latest research on Brucellosis here.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
