AbstractThe Avulavirus within the family Paramyxoviridae includes at least 22 different species, and is known to cause different types of infections and even be fatal in multiple avian species. There is limited knowledge of the genetic and biological information of Avulavirus species -2 to 22 in domestic and wild birds and the disease significance of these viruses in birds is not fully determined, although as many as 10 new distinct species have been identified from wild birds and domestic poultry around the world in the last decade. This study aimed to use PCR, virus isolation, and sequencing to genetically and biologically characterize Avian Orthoavulavirus 16 (AOAV-16) in wild birds and domestic poultry collected from different locations in China between 2014 and 2022. Of five isolated AOAV-16 strains (Y1 to Y5), only the Y4 strain had a hemagglutination (HA)-negative result. All of these isolates were low virulent viruses for chickens, except Y3 which was detected simultaneously with avian influenza virus (AIV) of H9N2 subtype. Furthermore, at least four different types of intergenic sequences (IGS) between the HN and L genes junction, and the recombination event as well as interspecific transmission by wild migratory birds, existed within the species AOAV-16. These findings and results of other reported AOAV-16 strains recommend strict control measures to limit contact between wild migratory birds and domestic poultry and imply potential threats to commercial poultry and even public health challenges worldwide.
