Gaps in brucellosis eradication campaign in sheep and goats in Republic of Macedonia: lessons learned.

Aim: To identify why "test and slaughter policy" for eradication of brucellosis did not significantly reduce the prevalence in sheep and goats in Macedonia.

Method: Coverage of sampled vs expected number of sheep and goats, absolute number of positive animals, prevalence, frequency distribution, and classes of disease prevalence were retrospectively analyzed at the village level for 2004-2006. A comparative analysis of the disease prevalence in the investigated villages was also performed.
