ABSTRACT

Avian paramyxoviruses (APMV), now classified as, avian avulaviruses according to the new classification, are part of the Avulavirinae subfamily within the Paramyxoviridae family. They are divided into twenty-two species based on a hemagglutination inhibition assay and molecular analyses. Furthermore, they are grouped into three genera Avian metaavulavirus (AMAV), Avian orthoavulavirus (AOAV) and Avian paraavulavirus (APAV) based on clustering into three distinct phylogenetical clades (ICTV, 2023). The recent taxonomical classification of the Paramyxoviridae family is displayed in Table 1.
