Abstract
AbstractWhite-tailed deer are susceptible to SARS-CoV-2 and represent a relevant species for surveillance. We investigated SARS-CoV-2 infection in white-tailed deer in Québec, Canada. In November 2021, 251 nasal swabs and 104 retropharyngeal lymph nodes from 258 deer were analyzed for SARS-CoV-2 RNA, whole genome sequencing and virus isolation and 251 thoracic cavity fluid samples were tested for neutralizing antibodies. We detected SARS-CoV-2 RNA in three nasal swabs from the Estrie region and virus was isolated from two samples; evidence of past exposure was detected among deer from the same region. Viral sequences were assigned to lineage AY.44, a sublineage of B.1.617.2. All deer sequences clustered with human GISAID sequences collected in October 2021 from Vermont USA, which borders the Estrie region. Mutations in the S-gene and a deletion in ORF8 encoding a truncated protein were detected. These findings underscore the importance of ongoing surveillance of key wildlife species for SARS-CoV-2.
