title: [Contagious bovine pleuropneumonia: immunoenzymatic test and kinetics of antibody formation in experimental infection. Relation of complement fixation, excretion and the study of circulating antigen].
abstract: An experimental reproduction of CBPP was implemented and the animals were surveyed for serology during 4 months. The ELISA/IgG test detects the antibodies few days after the CF test but is more precise for detection on the longer term. The early antibody detection can be done with the ELISA/IgM test. Circulating antigen (galactan) has been detected in a cow that died of an acute form of CBPP. Excretion of mycoplasmas starts 1 to 2 weeks before the seroconversion: the ELISA/IgG test remains positive during the excretion phase and even longer.
