Abstract
Complement fixing antibodies could be detected in the sera of cattle vaccinated with combined living blackleg-anthrax vaccine by modified complement fixation tests. Conventional direct complement fixation tests with bovine antibody-antigen systems often caused false negative reactions; however, in the modified test, when guinea pig complement was supplemented with fresh unheated normal rabbit serum, positive reactions were obtained and the sensitivity of the test was increased without loss of specificity.
