Table 4 Mean CFT titers (mean titer ± SEM; CFT) and number of goats and ibexes positive in Rose Bengal tests (RBT) from 20 to 90 days after conjunctival vaccination with Brucella melitensis Rev.1 strain (all samples were negative at D0 in both tests)

From: Brucella melitensis Rev.1 vaccination generates a higher shedding risk of the vaccine strain in Alpine ibex (Capra ibex) compared to the domestic goat (Capra hircus)
