Overview

Cross-species transmission revealed a novel canine coronavirus infecting an Amur tiger, suggesting evolution insights among carnivores.

Key Points

  • To investigate the presence and evolutionary implications of canine coronavirus in an Amur tiger.
  • Detected canine coronavirus RNA in a captive Amur tiger using metagenomic next-generation sequencing.
  • Conducted phylogenetic analysis to assess evolutionary relationships with other coronaviruses.
  • Performed recombination analysis to evaluate the genetic merge of different coronavirus strains.
  • Identified a novel canine coronavirus strain in the Amur tiger, linking it to known canine coronavirus lineages.
  • Found evidence of recombination with strains from various carnivores, indicating complex evolutionary interactions.
  • Expanded the accepted host range of canine coronavirus to include Amur tigers.
