Brucella melitensisB115-based complement fixation test to detect antibodies induced byBrucellarough strains

Antigenic relationship of Brucella ovis to Brucella abortus and Brucella melitensis using the complement fixation test.

WORTHINGTON, R. W. & MULDERS, MARIAS. G. Antigenic relationship of Brucellaovis to Brucella abortus and Brucella melitensis using the complement fixation test. Onderstepoort J. vet. Res., 36 (2) , 191-1 98, 1969. The CF test was used to investigate the serological relationship of Br. avis to Br. abortus and Br. melitensis. A definite antigenic relationship between Br. avis and Br. abortus could...

Microcomplement-fixation inhibition: a rapid and economical test to detect non-complement-fixing antibodies.

Complement-fixation inhibition test was adapted to the microtiter system. When cat and monkey non-complement-fixing antibody were used, the microtest was shown to be as sensitive as the conventional tube complement-fixation inhibition test.

Brucella abortus RB51 and hot saline extract from Brucella ovis as antigens in a complement fixation test used To detect sheep vaccinated with Brucella abortus RB51.

The efficacy of Brucella abortus RB51 and hot saline extract (HSE) from Brucella ovis as antigens in complement fixation (CF) tests was comparatively evaluated in detecting immune responses of sheep vaccinated with B. abortus strain RB51. For this study, four 5-month-old sheep were vaccinated subcutaneously with 5 x 10(9) CFU of RB51, and two sheep received saline. Serum samples collected at di...

Complement fixation test to assess humoral immunity in cattle and sheep vaccinated with Brucella abortus RB51.

The live attenuated Brucella abortus strain RB51 is a rifampin-resistant, lipopolysaccharide (LPS) O-chain-deficient mutant of virulent B. abortus 2308. The reduced O-chain content in RB51 prevents this bacterium from inducing antibodies detectable by the conventional serologic tests for bovine brucellosis diagnosis that mainly identify antibodies to LPS. The absence of available serologic test...
