Table 5.
Side-by-side comparison between the “lineage” system (Aldous et al., 2003), the “genotype” system (Diel et al., 2012a), and the updated classification system for NDV isolates proposed in this study. The names in bold font represent the sub/genotypes names based on the new classification and nomenclature systems
