Objective To characterise Newcastle disease virus isolates obtained in Victoria from 1976 to 1999 and identify the diversity of F0 cleavage signal. Design RT‐PCR using viral RNA extracted from positive NDV allantoic fluid was performed to amplify a segment of the NDV F and HN genes. Molecular characterisation of the nucleotide and amino acid sequences within the F0 cleavage site was undertaken. Results All isolates contained 'avirulent' F0 cleavage signal sequence of varied amino acid composition. Conclusions Molecular characterisation of past and present NDV F0 cleavage signal sequences will provide valuable epidemiological information and assist in understanding the genetic origins and relationships of outbreaks.
