Relativity Between Antigenic Variation and Epidemiologic Characters of Newcastle Disease Virus Strains Detected.by Monoclonal Antibodies
Abstract: Nineteen monoelonal antibodies (McAb) specific for Newcastle Disease Virus (NDV)was produced and used for the reactivity detection to 14 international reference NDV strains and 16 domestic NDV isolates by indirect immunofluorescent assay (IIF) . According to the results, the 30 NDV strains was divided into 8 groups from a to h. The antigenic variation of the strains which are different in epidemiology could be estimated by IIP test using the 19 MeAbs. It was showed tl, at there is relativity between antigen...
