Results obtained for samples taken concomitantly from goats tested for the presence of Coxiella burnetii DNA by PCR and for antibodies against Coxiella burnetii by three different serological tests (ELISA, IFA, and CFT). Circles and thin line, vaginal mucus samples; squares and dashed line, fecal samples; triangles and thick line, milk samples. Aborting animals (top) were sampled at D15 and D30 after the abortion peak. Samples from nonaborting animals (bottom) were taken at D15 and D30 after parturition or during the last gestation month, with the date of parturition being calculated from that of covering.
