Popis: Serological examination of 4 Border disease affected flocks of sheep using the neutralization test showed antibody prevalences between 14 and 96 %. Prevalence in yearlings in 3 of the 4 flocks was 37 %, it increased with age to 72 % in 5-year-old sheep. Possible reason for low prevalence (2 %) in yearlings in one of the flocks is discussed.
