Coronaviruses have a single-stranded positive RNA genome, corresponding to the largest known RNA genome, with about 27kb for AvCoV. The first 5’ two thirds of this genome, correspondent to a wide ORF1 (also called replicase gene), code for non-structural proteins (nsps) that are enrolled in viral transcription, replication a...

While, CPV is considered the most important cause of diarrhea, studies have shown an increasing prevalence and importance of CCoV around the world. Fatal CCoV infections have been described, however, there is limited information on the molecular diversity of CCoV in many parts of the world. In this study, canine fecal samples from diverse States of Brazil were screened by PCRs for CCoV an...
