This report describes Newcastle disease in peacock and the isolation and characterization of the virus. The virus had an intracerbral pathogenicity index of 1.71 and mean death time of 47 h. The isolate had multiple basic amino acids at the fusion protein cleavage site sequence ((110)GGRRQRRFIG(119)) with a phenylalanine at residue 117. Biological and molecular characterization revealed that the virus is velogenic. Phylogenetic analysis placed the isolate in genotype II.
