Circulation and Genetic Characterizations of Coronaviruses From Companion Animals in Chengdu, Southwest China: One-Year Postpandemic.

ABSTRACT: Coronaviruses (CoVs) can cross species barriers and endanger public health. Despite reports on their circulation and evolution in companion animals during the pandemic, postpandemic surveillance remains crucial. Therefore, during the first postpandemic year, 309 samples from 263 companion animals (cats and dogs) in Chengdu, China, were detected for CoVs using a universal assay based on Rdrp genes combined with one-generation sequencing. Four kinds of CoVs, including feline CoV (FCoV), canine CoV (CCoV), CRCoV, and SARS-CoV-2 (the first reported case of SARS-CoV-2 in a dog in mainland China, confirmed by viral nucleic acid detection and analysis), were detected with an overall positive rate of 21.7% (57/263); FCoV-I and CCoV-IIa were the dominant genotypes, and of these 57 positive cases, 7
