“…Porcine NoVs are classified in distinct genotypes within GII, bovine and ovine viruses belong uniquely to GIII, and murine NoVs are grouped in GV. Recently, several research groups have reported NoVs in domestic carnivores with diarrhea [10,11]. Canine NoVs (CaNoVs) genetically related to GIV have been reported in Italy, Greece and Japan [10-13], whereas viruses belonging to a proposed new genogroup (GVI) were found in fecal samples from dogs with diarrhea in Portugal and Italy [9,14-16].…”

BackgroundNoroviruses are important enteric pathogens in humans and animals. Recently, we reported a novel canine norovirus (CaNoV) in dogs with diarrhea belonging to a new genogroup (GVI). No data are available on exposure of humans to this virus.MethodsSera from 373 small animal veterinarians and 120 age-matched population controls were tested for IgG antibodies to CaNoV by a recombinant virus like particle based enzyme-linked immunosorbent assay.ResultsAntibodies to CaNoV were found in 22.3% of the veterinarians and 5.8% of the control group (p < 0.001). Mean corrected OD450 values for CaNoV antibodies were significantly higher in small animal veterinarians compared to the control group.ConclusionsThese findings suggest that CaNoV may infect humans and small animal veterinarians are at an increased risk for exposure to this virus. Additional studies are needed to assess if this virus is able to cause disease in humans.

“…NoV is classified into at least five genogroups (GI, GII, GIII, GIV and GV) based on their VP1 sequences . Additional genogroups (GVI and GVII) have recently been proposed . GI, GII, GIV and GVI are known to infect humans; of these, GII is the most prevalent .…”

Norovirus (NoV) and sapovirus (SaV) are important causes of human diarrhea. In this study, between 2007 and 2014 fecal samples were collected from 97 dogs and 83 cats with diarrhea and examined to determine the prevalence of NoV and SaV infections in Japan. To detect caliciviruses, approximately 300 bases targeting the polymerase gene were amplified using RT-PCR and subjected to phylogenetic and homology analyses. Specific PCR products were obtained from four canine and nine feline samples: two canine and one feline isolate were classified as NoV, two canine isolates as SaV and the remaining eight feline isolates as vesivirus (VeV). The three NoV isolates were classified into the same clade as that of known canine and feline NoVs; their homologies (75.9-92.3%) were higher than those with human genogroup IV (GIV) NoVs (59.1-65.9%). The homology of the feline NoV isolate with previously reported feline NoV isolates was particularly high (91.7-92.3%). Regarding SaV, the two canine isolates were classified into the same clade as known canine SaVs and their homologies (72.5-86.5%) were higher than those with other mammal SaVs (20.7-58.0%). The eight feline VeV isolates were assumed to be feline calicivirus. The present study is the first report of the presence of NoV-and SaV-infected dogs and cats in Japan. The findings suggest there are species-specific circulations of NoV and SaV among dogs and cats, in Japan.

“…Specifically, bovine NoVs are found in GIII, swine NoVs in GII (clusters GII.11, GII.18, and GII.19), and murine NoVs in GV. Canine NoVs were first reported in Italy in 2008 (5) and have since been found in other European countries (4,(6)(7)(8)(9). So far, all canine NoVs belong to GIV and the tentative new GVI (7).…”

We report the complete genome sequences of two novel isolates of norovirus isolated from the fecal swab specimens of dogs in Hong Kong. The complete viral genome is approximately 7.6 kb in length and consists of 3 overlapping open reading frames encoding the ORF1 polyprotein, VP1, and VP2, respectively. Analysis of the VP1 sequence suggested that these noroviruses are divergent from known noroviruses and may represent a novel phylogenetic clade within the genus.
