مستخلص: Caliciviruses are ssRNA viruses that can infect a wide range of hosts, including birds. While several avian caliciviruses have been discovered, their taxonomy and host distribution are largely unknown. We molecularly characterized a novel calicivirus (trumpeter swan calicivirus: TruSCV) in trumpeter swans over-wintering in south-west British Columbia, Canada. The positivity rate was 20.3% (14/69) and there were no significant differences in infection rates between males (5/34, 14.7%) and females (9/35, 25.7%) or among considered age groups (juveniles: 4/14, 28.6%; sub-adults: 1/9, 11.1%; adults: 9/46, 19.6%). Twelve infected swans died of lead poisoning, one because of starvation, and one from physical injuries. TruSCV complete genome possessed the typical organization and protein motifs of caliciviruses and a type 2 IRES and its closest relative was a virus circulating in Australian ducks. Phylogenetic analyses showed the existence of 34 different but monophyletic avian caliciviruses. These viruses, while having conserved genomic organization and protein motifs, possess different IRES types and group in several divergent clades, with only two of them corresponding to currently defined genera, highlighting the need for epidemiological investigations and systematic analyses to better define their taxonomy. Follow-up studies are needed to elucidate the diversity, distribution, and pathogenic potential of TruSCV.
