Figure 1. Phylogenetic analysis of the 1232–1560 nt sequence of the N protein gene of sequenced peste des petits ruminant (PPR) virus strains. The phylogram was generated by analyzing 1,000 bootstrap replicates; clusters were supported by bootstrap values >70%. Strains from Sudan are represented by prefixes: cam, camel; cap, caprine; ov, ovine. The Kabete 0 strain of rinderpest (RBOK) vaccine strain of rinderpest virus retrieved in GenBank (accession no. Z30697) was used as an outgroup. Scale bar indicates nucleotide substitutions per site.
