Distribution and reactivity of the IDvet screening ELISA–positive goats.

	Positive multispecies farms (sheep + goats)	Positive monospecies farms (only goats)	All farms
Positive farms	70	101	171
Farms with only 1 positive goat	55 (78.6%)	85 (84.2%)	140 (81.9%)
Positive goats	119	121	240
S/P ratio (median)	1.18	0.79	0.94

Positive farms = farms with at least one positive goat by IDvet screening ELISA. Most positive farms had only one positive goat. The S/P ratio of positive goats on multispecies farms (median = 1.18, IQR = 1.45) was statistically higher (p < 0.001) than that of goats on monospecies farms (median = 0.79, IQR = 0.50).
