ABSTRACT.- Abreu S.R.O., Castro R.S., Nascimento S.A. & Souza M.G. 1998. [CAEV nucleoproteic antigen production and comparison with Maedi-Visna antigen in the immunodiffusion test.] Produção de antígeno nucleoprotéico do vírus da artrite-encefalite caprina e comparação com o do vírus Maedi-Visna para utilização em teste de imunodifusão em ágar gel. Pesquisa Veterinária Brasileira 18(2):57-60. Depto Med. Veterinária, Universidade Federal Rural de Pernambuco, Rua D. Manoel de Medeiros s/n, Dois Irmãos, Recife, PE 52171-030, Brazil.
A comparison of Maedi-Visna virus (MW) and Caprine Arthritis-encephalitis virus (CAEV) antigens for detection of antibodies to CAEV was performed using sera from 120 goats. The sensitivity and specificity of the immunodiffusion test using MW antigen compared to that of CAEV antigen was 77.3% and 100%, respectively (X2, p < 0.01). These results suggested that only CAEV antigen should be used in immunodiffusion tests for CAEV diagnosis. |
