Tartalmi leírás:
Poxvirus infections have been found in 230 species of wild and domestic birds worldwide in both terrestrial and marine environments.
This ubiquity raises the question of how infection has been transmitted and globally dispersed. We present a comprehensive
global phylogeny of 111 novel poxvirus isolates in addition to all available sequences from GenBank. Phylogenetic analysis
of the Avipoxvirus genus has traditionally relied on one gene region (4b core protein). In this study we expanded the analyses to
include a second locus (DNA polymerase gene), allowing for a more robust phylogenetic framework, finer genetic resolution
within specific groups, and the detection of potential recombination. Our phylogenetic results reveal several major features of
avipoxvirus evolution and ecology and propose an updated avipoxvirus taxonomy, including three novel subclades. The characterization
of poxviruses from 57 species of birds in this study extends the current knowledge of their host range and provides the
first evidence of the phylogenetic effect of genetic recombination of avipoxviruses. The repeated occurrence of avian family or
order-specific grouping within certain clades (e.g., starling poxvirus, falcon poxvirus, raptor poxvirus, etc.) indicates a marked
role of host adaptation, while the sharing of poxvirus species within prey-predator systems emphasizes the capacity for crossspecies
infection and limited host adaptation. Our study provides a broad and comprehensive phylogenetic analysis of the Avipoxvirus
genus, an ecologically and environmentally important viral group, to formulate a genome sequencing strategy that will
clarify avipoxvirus taxonomy.
