Absence of neutralising antibodies to duck plague virus in the commercial duck and goose populations in West Germany (1980-1985).
Commercial duck and goose serum samples were examined in a viral neutralisation test in chicken embryo fibroblast cultures for the presence of specific antibodies against duck plague virus. All 2256 serum samples tested, which originated from different locations in West Germany from 1980 to Spring 1985, showed neutralising titres of less than 1.0 (log2 ) and were considered to be negative.
