An important objective of naming and classifying virus strains is to provide a meaningful identification to a distinct virus isolate. Relevant biologic characteristics of virus isolates such as serotype and pathotype assist in proper identification. In the case of infectious bursal disease virus (IBDV) serotyping is associated with protection and pathogenicity (Serotype 2 viruses are not pathogenic). Pathotyping of IBDV isolates provides valuable information for field personnel and researchers and should be included in the nomenclature. Unfortunately, pathotyping of IBDV has not been consistent mostly because of the lack of standardized procedures and criteria for designation of pathotypes. In this editorial, we attempt to provide standardized procedures and criteria for pathotyping. It was proposed to use genotyping in the nomenclature, but genotyping is not associated with biologic characteristics of the virus and viruses of the same genotype could differ in biologic characteristics. This renders the use of the genotype identity...
