Abstract
Two technical variations of enzyme-linked immunosorbent assay for the detection of antibodies to Coxiella burnetii were compared in this serosurvey on 20 Ontario dairy goat herds. Both a trichloracetic acid extract and a coctoantigen of purified coxiellas were used to sensitize the microtitration plates. Technical differences related to coating pH, serum dilutions tested and interpretation of results. Results agreed in 98.6% of sera examined, the differing sera were in the low titer borderline range. Only 20% of the herds had seroreactors.
