Figure 1From: Spatial distribution and risk factors of Brucellosis in Iberian wild ungulates Example of the typical distribution of optical density (% OD) results obtained by iELISA when testing the gold standard populations (from domestic goats) and its phylogenetically related Iberian wild goat ( Capra pyrenaica ) counterpart. The horizontal line represents the cut off selected for assessing the apparent prevalence of brucellosis.Back to article page
