Recebido em 4 de fevereiro de Aceito em 1 de agosto de Twenty-two fecal coromavirus were collected from dogs with ages ranging from 1 to 6 months, all of them non-vaccinated against CCoV.

The incubation period is one to three days.

Two genotypes of canine coronavirus simultaneously detected in the fecal samples of dogs with diarrhea. Development of a nested PCR assay for the detection of canine coronavirus. The authors are grateful to all dog owners and veterinarians who allowed the collection of the samples. Canine coronavirus antigen in canine lung tissue. Proceedings of the North American Veterinary Conference. Recent Advances in Canine Infectious Diseases. No mixed CCoV Types I and II and no geographic or chronological clustering in found amongst the 22 studied strains, what might mean that the CCoV detected lineages are continually perpetuated in Brazilian dogs.

It was discovered in in Germany during an outbreak in sentry dogs.

Regarding the Type II cluster, it can be noticed in Fig. CCoV is a member of the genus Alphacoronaviru s, family Coronaviridae, Order Nidovirales, with a single-stranded, positive-sense linear non-segmented RNA with 27kb and a helical nucleocapsid formed by the nucleocapsid N protein Masters, The virus is destroyed by most available disinfectants.

Dog diseases Alphacoronaviruses Animal virology. Identification of canine coronavirus strains from feces by S gene nested PCR and molecular characterization of a new Australian isolate. QI07AD11 WHOand it is usually given to puppies, who are more susceptible to canine coronavirus, and to dogs that have a high risk of exposure, foronavirus as show dogs. Canine coronavirus highly pathogenic for dogs. Phylogeny of canine coronavirus CCoV from brazilian dogs based on membrane protein partial sequences.

Although Types I and II co-infection were not detected in the present study, this must be interpreted with caution as such information could only be confirmed or discarded by the use of type-specific conventional or real-time PCRs Pratelli et al.

How can we approach emerging diseases? Characterization of divergent and atypical canine coronaviruses from Sweden. Recently, a second type of canine coronavirus Group II has been caniino to cause respiratory disease in dogs. Articles with ‘species’ microformats. This causes a much more severe disease than either virus can separately. Retrieved from ” https: Sequences were assembled with Cap-Contig in Bioedit cornoavirus.

In other projects Wikimedia Commons. Treatment usually only requires medication for diarrhea, but more severely affected dogs may require intravenous fluids for dehydration. Coronavirus infection of the intestinal villi makes the cells more susceptible to parvovirus infection.

Views Read Edit View history. There is a vaccine available ATCvet code: Intestinal disease may be related to virus-induced apoptosis programmed cell death of cells of the epithelial mucosa of coronavrius small intestine. As a conclusion, this study demonstrates that both Types I and II CCoV occur in Brazil, and a supposed Brazilian sub-lineage in Type II will be investigated in further detail by sequencing of other parts of the genome.


Mean amino acids identities between Type II sub-lineages 01 and 02 were Exclusive coronavirhs were used for sample preparation and RNA extraction, reverse transcription and amplification reactions as well as for electrophoresis in order to avoid amplicon carry-over.

The virus invades and replicates coronavirks the villi of the small intestine. From Wikipedia, the free encyclopedia. Textbook of Veterinary Internal Medicine 4th ed.
