Phylogenetic tree of the complete nucleotide sequence of the F gene for two representative isolates. ML Phylogenetic tree of complete nucleotide sequence of Class II Newcastle diseases viruses. Ethiopian isolates included in this analysis (KJ958913_13VIR3936-1 and KJ958914_13VIR3936-27) are labeled in red. The Nomenclature system used in the phylogenetic tree is based on (Diel et al.2012). The numbers at branch points represent bootstrap values.
