Molecular characterization of a virulent canine coronavirus BGF strain

Molecular characterization confirms the presence of a divergent strain of canine coronavirus (UWSMN-1) in Australia.

Canine coronavirus (CCV) UWSMN-1 was originally identified from an outbreak of fatal gastroenteritis in breeding colonies. In this report, we examined whether UWSMN-1 represents a novel divergent strain or is the result of recombination events between canine and feline coronavirus strains. Sequencing of various regions of the spike and polymerase genes confirms that UWSMN-1 is widely divergent ...

Molecular characterization of haemagglutinin-neuraminidase gene among virulent Newcastle disease viruses isolated in Iran

Background: Virulent Newcastle disease virus (vNDV) causes great economic losses to the poultry industry throughout the world. Despite the endemicity of Newcastle disease (ND) and occurrence of recurrent outbreaks, the nature and genetic features of circulating NDV strains in Iran are largely unknown. Aims: This study was conducted to characterize 13 NDV isolat...

Characterization of canine coronavirus spread among domestic dogs in Vietnam

Canine coronavirus (CCoV) is an important pathogen that causes enteritis in dogs, but there is no information on CCoV infection in Vietnam. To examine the prevalence of CCoV infection among Vietnamese dogs, 201 serum samples were analyzed by virus-neutralization (VN) test. The results showed that antibody against CCoV-II was present in 87 dogs (43.3%). To detect genes of CCoV, fecal samples col...
