“…CCoV was detected by selectively amplifying a 409bp fragment of M gene as previously described [26]. All the positive samples were subjected to screen for other canine enteric virus by the methods previously described, including CPV [27], CaAstV [28], CaKV [29], TTCaV [30]. In addition, primer pairs EL1F/EL1R, CEPol-1/TGSP-2 and S5F/S6R, which amplify CCoV-I, CCoV-IIb and CCoV-IIa genes, respectively, were used to differentiate gene types of CCoV, as previously described [31][32][33].…”

A B S T R A C TAs the outbreaks of COVID-19 in worldwide, coronavirus has once again caught the attention of people. Canine coronavirus is widespread among dog population, and sometimes causes even fatal cases. Here, to characterize the prevalence and evolution of current circulating canine coronavirus (CCoV) strains in China, we collected 213 fecal samples from diarrheic pet dogs between 2018 and 2019. Of the 213 samples, we found 51 (23.94%) were positive for CCoV. Co-infection with canine parvovirus (CPV), canine astrovirus (CaAstV), canine kobuvirus (CaKV), Torque teno canis virus (TTCaV) were ubiquitous existed. Mixed infection of different CCoV subtypes exists extensively. Considering the limited sequences data in recent years, we sequenced 7 nearly complete genomes and 10 complete spike gene. Phylogenetic analysis of spike gene revealed a new subtype CCoV-II Variant and CCoV-IIa was the most prevalent subtype currently circulating. Moreover, we identified strain B906_ZJ_2019 shared 93.24% nucleotide identifies with previous strain A76, and both of them clustered with CCoV-II Variant, which were not well clustered with the known subtypes. Recombination analysis of B906_ZJ_2019 indicated that strain B906_ZJ_2019 may a recombinant variant between CCoV-I and CCoV-II, which is consistent with strain A76. Furthermore, amino acid variations widely existed among current CCoV-IIa strains circulating in China and the classic CCoV-IIa strains, in spite of the unknown functions.In a word, we report a useful information as to the etiology and evolution of canine coronavirus in China based on the available sequences, which is urgent for the devise of future effective disease prevention and control strategies.

“…GeneBank accession numbers for each complete kobuvirus ORF used in this analysis are quoted on their respective branches. described in domestic dogs in a larger geographical area, including the USA (Kapoor et al, 2011;Li et al, 2011), Europe (CarmonaVicente et al, 2013Di Martino et al, 2013) and Asia (Oem et al, 2014). CaKV infection is often associated with diarrhea and other clinical signs (Carmona-Vicente et al, 2013;Li et al, 2011), even though asymptomatic infections also occur (Kapoor et al, 2011).…”

Molecular characterization of canine kobuvirus in wild carnivores and the domestic dog in Africa

Knowledge of Kobuvirus (Family Picornaviridae) infection in carnivores is limited and has not been described in domestic or wild carnivores in Africa. To fill this gap in knowledge we used RT-PCR to screen fresh feces from several African carnivores. We detected kobuvirus RNA in samples from domestic dog, golden jackal, side-striped jackal and spotted hyena. Using next generation sequencing we obtained one complete Kobuvirus genome sequence from each of these species. Our phylogenetic analyses revealed canine kobuvirus (CaKV) infection in all four species and placed CaKVs from Africa together and separately from CaKVs from elsewhere. Wild carnivore strains were more closely related to each other than to those from domestic dogs. We found that the secondary structure model of the IRES was similar to the Aichivirus-like IRES subclass and was conserved among African strains. We describe the first CaKVs from Africa and extend the known host range of CaKV.

“…The aa identity between CaKoVs and feline kobuvirus (FeKoV) in the full-length genome ranged from 82.0% to 86.0%, while aa identity to human AiV was 79.0% (Cho et al, 2014). Molecular investigations worldwide have revealed that CaKoVs are common in both symptomatic and asymptomatic dogs (Kapoor et al, 2011;Li et al, 2011;Carmona-Vicente et al, 2013;Di Martino et al, 2013;Oem et al, 2014). By converse, there is no information on the epidemiology of the newly described FeKoVs after their initial description in Asia (Chung et al, 2013;Cho et al, 2014).…”

Kobuviruses have been identified in the enteric tract of several mammalian species but their role as enteric pathogens is still not defined. In this study, feline kobuviruses were found in 13.5% of cats with diarrhoea, but not in asymptomatic animals. In the full-length genome, one such strains, TE/52/13/ITA, displayed the highest nucleotide identity (96.0%) to the prototype strain FK-13. These results provide firm evidence that kobuviruses are common constituents of feline enteric viroma and that they are not geographically restricted to the Asian continent, where they were first signalled.
