Summary
The study tested a panel of 1,562 Australian sheep sera and found that the percentage of samples testing positive in the ELISA was 0.3% and 3.7% at two separate laboratories. The percentage of samples testing positive in the CFT at 1 in 4 at the two laboratories was 17% and 11% respectively. There is a statistically significant difference between the results obtained with the Institut Pourquier Chlamydophila abortus antibody ELISA and the complement fixation test (P < 0.001). The ELISA gave repeatable results within a laboratory and reproducible results between laboratories.
