Molecular epidemiology and phylodynamics of goose haemorrhagic polyomavirus

Goose haemorrhagic polyomavirus (GHPV, or Anser anser polyomavirus 1) is a small dsDNA virus of the Polyomaviridae family. The virus infects the internal organs causing haemorrhagic nephritis and enteritis of geese that may be fatal for goslings. In this study, GHPV positivity was examined in goose and duck samples collected in Hungary between 2005 and 2019. In this period, 384 of the investigated 1,111 specimens were diagnosed as GHPV-positive by PCR assay. Twenty-two GHPV genomes were sequenced and subjected to phylogenetic and evolutionary analysis. Based on the sequence data, the mean evolutionary rates were estimated 6.57 × 10-6 -5.82 × 10-5 s/s/y for both GHPV complete genomes and individual genes, with negative selection acting on each gene. When GHPV VP1 sequences originating from wild birds were also included in the analyses, the nt and aa mutations inflated the substitution rate to 1.54 × 10-4 s/s/y that may imply adaptation of the virus to novel host species. Our data suggested the co-circulation of various GHPV strains in Hungarian goose farms; the source of these may be persistently infected domesticated or migratory wild birds. Detection and characterization of GHPV in wild birds and domestic waterfowls may help to elaborate new strategies for more effective disease control and prevention.
