*Results are expressed as optical density (OD), and interpretation (positive/negative) was made by using the following cut-offs: in sheep: 0.369 (0.1718 + 3 × 0.066); goats: 0.406 (0.211 + 3 × 0.065); human 0.32 (0.17 + 3 × 0.049); dogs: 0.493 (0.37 + 3 × 0.041).
†One sample of positive and negative control samples was added to each plate. Sheep and goat sera from animals with a known history of O. ovis exposure were used. When positive sera were not available (human and dogs), we used only negative sera, and the cut-off was estimated as the mean OD of the negative sera plus 3 SDs (7).
