Genome Organization of Canada Goose Coronavirus, A Novel Species Identified in a Mass Die-off of Canada Geese.

ABSTRACT: The complete genome of a novel coronavirus was sequenced directly from the cloacal swab of a Canada goose that perished in a die-off of Canada and Snow geese in Cambridge Bay, Nunavut, Canada. Comparative genomics and phylogenetic analysis indicate it is a new species of Gammacoronavirus, as it falls below the threshold of 90% amino acid similarity in the protein domains used to demarcate Coronaviridae. Additional features that distinguish the genome of Canada goose coronavirus include 6 novel ORFs, a partial duplication of the 4 gene and a presumptive change in the proteolytic processing of polyproteins 1a and 1ab.
