Maedi-visna Virus (MVV) / Caprine Arthritis Encephalitis Virus (CAEV)

ID Screen® MVV / CAEV Indirect


Indirect ELISA kit for the detection of antibodies against Maedi Visna (MVV)/CAEV viruses in sheep and goats serum, plasma or milk samples

The use of a mix of peptide antigens results in superior test performance (sensitivity, specificity, and differentiation between positive and negative results).






  • Reliable and accurate : clearly separates positive and negative results, with high sensitivity – detection of all genotypes (including A; B and E) – and high specificity
  • No non-specific reactions due to BTV-vaccination, thanks to the use of peptide antigens. Other ELISAs based on recombinant or purified viral antigens have given nonspecific reactions in BTV-vaccinated populations (1)
  • Easy-to-use, with results in 90 minutes
